DC to AC inverters are used for converting direct current (DC) into alternating current (AC).

Power supplies are devices that produce AC or DC power.

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

Gearmotors consist of an AC or DC motor with an integral gearbox or gear head that steps delivered speed up or down.

AC motors include single, multiphase, universal, induction, synchronous, and gear motors.

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

DC power supplies accept an input power and output the desired form of DC power.
