Geared motor is a commonly used term that designates a hoist that derives its lifting and lowering power from a mechanical setup involving a gear set and pneumatic or electric motor.
As the name implies a gear motor or geared motor is a motor having an attached gear assembly. The gear assembly or gear train enable the gear motor to provide greater torque at a lower RPM than the motor alone would be capable of providing.
That is, gear motor refers to a combination of a motor plus a reduction gear train.These are often conveniently packaged together in one unit. The gear reduction or gear train reduces the speed of the motor, with a corresponding increase in torque. Gear ratios range from just a few to huge. A small ratio can be accomplished with a single gear pair, while a large ratio requires a series of gear reduction steps and thus more gears. There are a lot of different kinds of gear reduction.
