    DC Motors

    Permanent Magnet Direct Current brush type motors are a great option for applications with high starting torque requirements because of their linear speed-torque curve. DC motors and gearmotors have a standard brush life of 2000+ hours, and they are great for applications with easily accessible motors and operations that don’t require a long life. Because speed and voltage are linearly related, it is easy to control the speed of permanent magnet motors.

    AC Motors

    AC motors (alternating current) are a great choice for applications needing relatively low, consistent speed over a wide range of torque. Groschopp offers two and four pole induction motors with single and three phase inputs making it easy to find the right fit. AC induction motors are a great option for low power and low starting torque applications where speed control isn’t important. The lack of common wear parts, such as brushes and commutators, make AC motors extremely reliable, resulting in long life (20,000+ hours) with little maintenance. AC motors and gearmotors can be run with or without a variable frequency drive (VFD), depending on the amount of control needed.

  • Brushless

    Brushless Motors

    Brushless DC Motors combine the life-extending and easy-to-maintain configurations of AC induction motors with and high starting torque and good speed regulation of brush type PM motors. This “best of both” motor allows for superior efficiency and power density at a very quiet noise level. Because BLDC motors use rare earth magnets as opposed to the ceramic magnets of DC brush type motors, they have a higher power density and require a speed control to operate.

    Universal Motors

    Universal motors are great for shorter life applications needing extremely high speeds (20,000+ RPMs), high starting torque and high power density. They have a higher power density than other motor types because the open design and fan allow heat to dissipate better. Universal motors are unique in that they can operate on either AC or DC power. They are the least expensive type of motor, making them an excellent option for intermittent duty applications that allow for higher noise levels, maintenance requirements and a shorter life. Groschopp’s Universal motors are always custom built to fit individual circumstances and environments.

Oil or Grease: Load (Part 3/4)

Factor #4: Load As you might guess, an increased load increases the stress upon your motor, just as a full trailer increases the stress on your truck or a child on your shoulders puts increased pressure on your back. In motors, this stress produces heat, which creates a heightened potential for lubricant evaporation. Spill a […]

Oil or Grease: Operation & Vibration (Part 2/4)

Factors #2 & #3: Hours of Operation and Vibration Weather extremes are hard to miss. Even if you don’t have a thermometer somewhere nearby or an app on your phone (or a degree in meteorology), it doesn’t take much to realize what sweltering hot or blistering cold feels like. As a result, it’s not too much […]

Oil or Grease: Climate (Part 1/4)

Factor #1: Climate Unless a person lives on a space shuttle or in a vacuum-sealed, climate-controlled, sterilized building where no one leaves and nothing enters, people can expect to find the evidence of climate on the surrounding area and its objects—machinery, motors, patio awnings, washing machines or otherwise. Both internal and external wear on outdoor […]

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.
