Manually operated production equipment requires the operator’s ability to control the motor when it is turned on or off and when modifying the speed of the motor during operation. A variable speed switch allows machine operators to control various functions, maximizing production efforts and preventing accidents. Discover the power and versatility of variable speed foot switches in various applications.
How Does a Variable Speed Motor Switch Work?Often called “foot potentiometers,” variable speed motor switches provide a viable way to operate equipment while freeing the operator’s hands for other tasks. They are built to ensure precise and efficient control over machine functions. The foot pedal switches control the speed by adjusting the energy flow from the main source. |
Unique Features and Capabilities
Variable speed motor switches come with different types of shields to withstand harsh environments and unique modes to cater to specific applications. Most variable speed foot control companies offer pedals with or without built-in foot guards.
For example, the Hercules foot potentiometer by Linemaster features a strong protective cast aluminum shield and cast iron housing with a NEMA IP56 enclosure for greater durability. It also has a spring-loaded treadle, an option to add an auxiliary switch contact rated at 15 Amps 125-250 VAC and an optional potentiometer with 5,000 or 10,000 Ohm values.
What Are the Common Operational Modes?
Variable speed foot switches offer various modes of operation, such as:
- Momentary mode lets the operator press the foot pedal to start the machine. Lifting the foot off the pedal stops the process, springing the pedal back into its initial position.
- Maintained mode requires pressing the foot pedal once to start the machine and then pressing it once again to stop it.
- Proportional output signifies that while the foot switch is pressed, the output is proportional to the movement of the potentiometer.
- Anti-trip mode means there’s a special lever for additional safety. This only allows the pedal to be activated when the lever is pushed in the forward position.
Typical Applications for Foot Pedal Potentiometers
Foot pedals for variable speed motors are applicable for manually operated equipment. Some common applications include machines needed for:
- Sewing textiles
- Shearing
- Cutting
- Sealing
- Stamping
- Presses
- Punching
- Spot welding
Advantages of Using a Variable Speed Motor With a Foot Pedal
Instead of using their hands, the operator can depend on the variable speed foot pedal to adjust the speed, as well as start and stop these machines. This action offers many benefits, including:
- Improved production efficiency
- Enhanced output
- Safety in operations
- Better operator comfort
- Reduced fatigue due to repetitive tasks
