Motor contactors are relays with large current capacity for connecting and disconnecting a motor from the power supply.

Motor starters and contactors are motor-starting devices.

DC motors are most commonly used in variable speed and torque applications.

Motor controllers receive supply voltages and provide signals to motor drives that are interfaced to motors.

Electrical contact and electrode materials are soft, high conductivity, oxidation resistant materials used in circuit breakers, relays, and for EDM applications

DC servomotors are generally small and powerful for their size, and easy to control.

Linear motors generate force only in the direction of travel.
