Selecting a Motor Controller

When choosing a motor controller for your application, several crucial factors need to be taken into consideration. Keep the following points in mind as you make your selection:

Contact us to help you choose

Do you know the full load current of your device?

  • What is Full Load Current?
    The full load current is the amount of current a motor draws at rated load and voltage to produce its rated output horsepower.

  • Why It Matters for AC Drives
    When selecting an AC drive, ensure its full load current rating is equal to or higher than the motor’s full load current. This guarantees performance and safety.

  • Tip for Choosing the Right Drive
    In addition to full load current, consider control methods, protection functions, and heat dissipation. Ensure overload and short-circuit protection and compliance with safety standards.

What Coil Voltage Do You Require?

The coil voltage of your motor control device must match the control circuit's voltage. It can be the same as your line voltage or independent of your motor’s voltage. We offer a variety of coil voltage options for Building Automation and Control systems, including 12VDC, 24VDC, 24VAC, 110VDC, 120VAC, 208-240VAC, and 400-480VAC.

What is Your Motor’s Input Voltage?

Knowing your motor’s input voltage is crucial when selecting the right motor control device. Improper sizing can cause equipment damage and pose safety risks. Always ensure your motor's input voltage matches or is below the rating of the motor control device.

Interrupt Rating

Some motor controls include short-circuit protection, such as manual motor starters. The interrupt rating indicates the maximum current they can safely stop without damage, ensuring reliable operation and system safety.

What Overload (O/L) Range Does Your Application Need?

It’s important to ensure the Full Load Amp (FLA) rating of your motor is within the overload (O/L) range of the motor control.

  • Exceeding the O/L range by drawing too many amps can trip the device, protecting the motor from damage.
  • Selecting an O/L range lower than your motor’s FLA may cause frequent, unnecessary trips.
  • Choosing an O/L range much higher than your FLA may fail to detect overloads properly.

Choosing the correct O/L range ensures optimal protection and performance.

Accessories

We carry a wide variety of accessories to go along with our robust selection of motor controls. Some of these accessories include the following options:
