DC
Permanent Magnet Direct Current or DC brush type motors are a great option for applications with high starting torque requirements because of their linear speed-torque curve. DC motors with brushes work well in applications with easily accessible motors and operations that don’t require a long life. DC motors have a standard brush life of 2000+ hours. Because speed and voltage are linearly related, speed control of DC motors is simple.

AC
For applications needing relatively low, consistent speed over a wide range of torque, alternating current or AC induction motors are a great choice. Groschopp offers two and four pole AC motors with single and three phase inputs making it easy to find the right fit. AC 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.

Brushless
Permanent Magnet Brushless DC motors (or Brushless motors) combine the life-extending (20,000+ hours) and easy-to-maintain configurations of AC induction motors with and high starting torque and good speed regulation of DC brush type motors. This “best of both” motor allows for superior efficiency and power density at a very quiet noise level. Because Brushless DC 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 control to operate.

Universal
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. GroschoppR
