Buy DC Drives: 5 Helpful Hints

Whether you’re a distributor in the industrial controls market needing to buy DC drives direct or have need of a particular type of drive for your plant or facility, determining what type of drive to purchase can be a little confusing. There are various types of drives depending on your application, motor horsepower ratings, drives designed to work with certain types of motors, etc. DC drives can be regenerative or non-regenerative as well, so it’s important to take your time and get to know what’s available so you can compare drives, pricing, and other important factors. No matter what reason you need to buy DC drives, we’ve put together a few helpful hints to simplify the process:

1. Type of DC Drive to Purchase – Non-Regen or Regenerative

Do you have a new application or need to replace an older DC drive? Either way, you’ll need to understand what type of drive to purchase? Does your application require a non-regenerative drive, which is a basic Quadrant I or Quadrant III drive that controls the motor’s speed and torque in just one direction? Or perhaps you need a Quadrant II or Quadrant IV regenerative DC drive, which can control the speed and direction of the motor’s rotation as well as the torque direction of the motor. Regenerative drives are often preferred for more complex applications because these also enable the motor to work similar to a generator, converting mechanical energy to electrical energy to enhance energy efficiency.

2. Variable Speed Drives – Benefits

Before you buy DC drives, also learn more about the benefits of a variable speed drive (VSD). These adjust the voltage of the motor in order to vary the speed. Both AC and DC drives can be variable speed drives. VSDs can be adjusted to fit the application so that production is greatly improved. By varying the speed either less than or more than the base speed of the motor, the VSD helps to achieve maximum output for the machinery or equipment without putting unecessary strain on the motor.

3. Horsepower and Torque Requirements

With any application, the DC drive must be the right fit for the horsepower rating and torque requirements of the motor. When replacing a drive on a wound rotor motor, it’s important the the drive match or exceed the motor’s starting torque. Horsepower can be selected based on the torque requirements of the motor and the machine that’s being driven. You might see a horsepower rating of 250, 300, 400 or 500, with various speeds (RPM) of operation. These two factors are used to determine the torque requirement throughout a particular speed range. If you have multiple DC drives to replace or install, the calculations can vary from one to the next. Determining horsepower/torqe requirements is easier with the help of an expert. You can call Carotron directly to speak with an engineer or technician if you need assistance before purchasing DC drives- 1-888-286-8614.

4. DC to AC Drive Conversions

If you’re thinking of converting to an AC drive, there are several considerations. Determine which option will be more cost effective. An older DC motor that still runs well may be upgraded to work more smoothly by simply installing a new DC drive with all the latest features. However, if the motor is beyond repair, you might save time and money for the long haul by converting to an AC motor and AC drive/inverter control system. A new DC drive chassis can often replace the existing one by simply removing the old drive but re-using the existing contactors, fuses, etc. On the other hand, converting everything to an AC motor and drive will require the replacement of the complete control cabinet, re-wiring of the motor, and other conversion needs. We provide a more in-depth article on this subject in the article titled, “Helping Your Customers Decide whether to Keep the DC Drive or Replace with an AC Drive.”

5. Where to Buy DC Drives?

As an end-user of the product, you can buy DC drives from distributors that offer industrial control products. Carotron, for instance, has a number of distributors around the world that carry our DC drives and other products. Elite ® Pro Series is our latest DC drive release, but we also offer a variety of other DC drives including Edge Guider, Blazer ® IV, Choice® Series, Trooper® IV, etc.

Single Phase vs Three Phase Transformers

Candice — Mon, 23 Jan 2012 21:19:08 +0000

Single Phase vs. Three Phase Transformers

With a single phase power system, power lines are used as an input source, but there is only one primary and one secondary winding that’s required to achieve the voltage transformation. The single phase transformer, therefore, uses these two windings to transform the voltage.

Single phase transformers come in various models, which differ based on horsepower range, taps, mounting type (such as wall mount), dimensions, KVA and shipping weight. You might see these labeled as ’240/480 VAC Primary and 120/240 VAC Secondary, 1 PH, 60 Hz” when ordering, and a listing of models available for this type of transformer.

Three phase power works differently in that power is generated by rotating three windings or coils through a magnetic field within the generator. The three windings are spaced apart by 120 degrees, and generate power as they rotate through the magnetic field. The generated power is then sent out on three different lines, which is why it’s called “three phase” power.

For a three phase transformer to work, it must have three windings or coils connected in the proper order to match the incoming voltage. It then transforms the incoming voltage to the voltage level needed while maintaining proper polarity and phasing.

Three Phase Power for Industrial Applications

Industrial loads are best powered by three phase electricity for efficiency purposes. Three phase power helps heavy duty equipment to operate more smoothly because the voltage can be transmitted for long distances using a smaller conductor. If single phase power is needed, it can be harnessed between any two phases within a three phase system. Single phase power can be implemented between the ground and just one of the phases in some applications.

Using three conductors in a three phase system can provide approximately 170 percent more power than a single phase system, which only has two conductors.

How Three Phase Transformers Work

Three phase transformers have a three-section iron core, with each section having a primary and secondary coil or winding. At the plant, the three primary coils are connected to provide the proper polarity or sequence. The configuration of the primary three windings is called “Delta.” The three secondary windings are also connected at the plant but these will be configured as either “Delta” or “Wye” depending on the voltage requirements.

Like single phase transformers, three phase transformers come in various models and can be differentiated by KVA, Taps, horsepower range, mounting (such as wall or floor mount), dimensions and weight. These may be labeled similar to the following when ordering, “460 VAC Primary, 230 VAC Secondary, 3 Ph., 60 Hz.”

Loads and Transformers

The type of transformer being used depends on the load. For three phased loads, there must be a three phase supply and transformer. The supply can be either single or three phase with a single phase load; however, the transformer must be single phase and have a connection between the primary and two lines on the three phase circuit.

Comparison of Air-Cooled and Liquid Cooled Eddy-Current Brakes

Comparison of Air-Cooled and Liquid-Cooled Eddy Current Brakes

Eddy-Current brakes provide fast, reliable load control for a variety of industrial applications. Eddy-Current brakes also offer moderate inertia and have a particularly high load capacity. These work well for the lower RPM range that’s typical of most industrial motors. Two main types of Eddy-Current brakes are air-cooled and liquid-cooled brakes. Let’s compare how these work as well as their similarities.Air-Cooled Eddy-Current Brakes

Air-cooled type brakes feature a rotating member or rotor and are keyed to a straight-through double extension shaft and a stationary brake coil. These are usually the most cost effective brakes in applications that do not require stall-speed loading. Air-cooled brakes usually cost less than liquid-cooled because there’s no need for an external water supply or resistor banks. Air-cooled Eddy-Current brakes also usually allow for more flexibility than hydraulic pumps.

Liquid-Cooled Eddy Current Brakes

Liquid-cooled brakes are used in more demanding applications, such as those requiring a higher RPM limit, temperature independence (continuous duty), and lower system inertia. These offer quick load control and work well with industrial motors that do not require motoring or stall speed loading. Same as air-cooled brakes, liquid-cooled brakes feature a rotor and are keyed to a straight-through double extension shaft and a stationary brake coil. But unlike air-cooled brakes, these are also keyed to an automatic water piping system for flow-through liquid cooling.

Similarities

Both types of Eddy-Current brakes provide controlled deceleration of the motor at variable speeds. They offer smooth response because the rotating and stationary parts have no physical contact. Having no contact also eliminates shock loading and extends the equipment life.

Both types of brakes may have an optional tachometer generator that provides feedback to the controller (using feedback signal). This tachometer generator is mounted externally for the air-cooled brakes and internally for the liquid-cooled brakes. Its signal is compared against a reference signal inside the controller, resulting in smooth, accurate and controlled braking. Constant speed and torque may be achieved as well.

Common industrial applications for Eddy-Current brakes include load braking, centrifuges, overhead cranes and dynamometer testing.

Carotron now offers Air-Cooled and Liquid Cooled Eddy-Current brakes from DSI Dynamatic, rating from .25 to 4000 horsepower. There’s also a wide selection of Dynamatic drives to meet control demands of today in many industrial settings.

Rock Crusher / Pick Breaker Feeder Conveyor Drive

by John N. McMurray
Sales Engineer
Carotron, Inc.

Functional Description

A self-contained feeder conveyor drive that senses current on the Rock Crusher / Pick Breaker Motor, compares this with a desired, preset level (typically around 95 percent of full load), and modulates the rate of the feed conveyor to maintain this load. The unloaded pick motor draws a low current that causes the controller to call for a maximum conveyor speed.

As product is delivered to the conveyor inlet and up to the breaker section, pick/crusher motor current increases, reaching a trigger point at which the feeder conveyor drive begins to reduce conveyor speed. A balance is established that keeps the feeder conveyor at a speed that maintains the pick motor current at the preset level. If the incoming material mix changes, the corresponding change in motor current causes the conveyor speed to move up or down.

Drive Compatibility

Versatile output will interface with most standard industrial variable speed drives (typically, ±10 VDC):

1 – DC Drives 2 – AC Inverter Drives 3 – Eddy-Current Drives 4 – Hydraulic/Hydrostatic Drives

Packaging

The following components are mounted on a rolled-edge steel sub-panel for mounting in customer’s enclosure:

– AC Line circuit breaker (operator handle and shaft are included for customer mounting on front panel)
– Mercury contactors for Pick Motor and Conveyor Motor/VS Inverter
– Electronic motor overload relays
– Pick motor current sensing transducer
– PLC Industrial Controller provides supervision of these functions:
       – Operational sequencing
       – Safety interlocks, limit switches, and operational sensors
       – Conveyor zero-speed and belt breakage through customer-supplied inductive prox sensor
– HMI Touch Screen shipped loose for customer mounting on front panel of enclosure

Optional Features for Feeder Conveyor Drive

– Sub-panel mounted and wired in a welded steel enclosure w/ HMI on enclosure cover
– Data monitoring and recording in real-time with extended storage capability
– Remote Process and Data monitoring through local plant network and Internet
– Remote troubleshooting and programming with plant-controlled limited access
– Automatic notification of system malfunctions through e-mail, text, cell phone, etc. (with Internet connection)

Applications

*Automotive: Test stands for measuring and controlling torque, speed and horsepower (input and output), of a manufacturer’s product.

*Chain Conveyors: Many chain-type conveyors that are utilized automotive and coating plants require adjustable speed for acceleration and deceleration control, product transfer, general production rate control and controlling specific product operations (dyeing, painting, dipping, etc.)

*High Torque: Eddy-current drives are well suited for high-torque applications because they can provide high torque over a wide speed range.

*Tension Control & Winder: The simple, flexible speed adjustment and control qualities of the Dynamatic® Eddy-Current provides an accurate and inexpensive means of tension control and winder applications.
