AC Motor Speed Control

AC Motor Speed Control

Using an AC motor speed control is essential to many applications. AC motor controls allow the gear motor to continually change speeds without changing the performance of the motor. Our AC speed controllers are engineered to compliment our line of AC inverter duty motors; they are programmed to work better with our motors than the other drives on the market.

Brushless Speed Control

Brushless Speed Control

Electronically-commutated Brushless DC motors requires the use use of a brushless speed control to operate. Our speed controllers are available in chassis, NEMA 4X, and digital enclosures. Our brushless motor and control packages are designed to work together to provide optimal performance.

How to use the Motor Search Tool

Narrow your search by selecting motor type, gearbox, voltage, and phase options for your desired motor.

Select a dominant variable: choose one of the three parameters to narrow your search. The selected variable determines which slider bar you will be able to manually move.

Use the slider corresponding to your dominant variable to further narrow your motor selection. The other sliders will automatically move to show available ranges based on the range of your selected variable.

Results will upload as your search criteria changes. If you have any questions regarding your results or how to use the search tool, you can chat with us using the green tab on the left-hand side of your screen.


Note: Groschopp Universal motors are custom built to fit your application so no additional options are available to narrow the search. Selecting the Universal motor type will prompt a message taking you to the Universal product page.
