Gearmotors transmit input torque from a motor to an output shaft through a series of integrated gears, decreasing speed and increasing torque. The reduced speed and increased torque make gearmotors suitable for use in demanding production settings. AC gearmotors are powered by single-phase, or three-phase AC voltage, while DC gearmotors require DC voltage, usually supplied by a battery, or other DC power supply. Universal AC/DC gearmotors feature the flexibility of utilizing battery, or building power supplies. Gearmotor accessories enhance the use, installation, and flexibility of gearmotors. Gearmotor replacement parts repair worn or damaged components in compatible gearmotors.
