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.

Motor starters and contactors are motor-starting devices.

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

Motor coils are used with motors, generators, stators, and armatures

Safety relays and control modules differ from conventional relays in that they have force-guided or positive-driven contacts

Electromechanical relays are devices that complete or interrupt a circuit by physically moving electrical contacts into contact with each other
