Select a conveyor gear motor from belt speed and pulley diameter, then check incline holding, accumulation starts, drive mounting and VFD control.

Gear reducer sizing in five steps: output speed, running torque, service factor, ratio and verification, with a complete worked incline conveyor calculation.

A stalled geared motor is usually a supply, brake or load problem, not a gearbox failure. Follow six diagnostic steps and recalculate the torque before replacing it.

Read an electric motor gearbox datasheet in the right order: service factor by duty class, thermal power rating, backlash, lubrication and mounting position.

Choose an AC gear motor by phase, then frequency, then voltage. Compare single-phase and three-phase starting torque, 50/60 Hz speed and torque changes, and duty.

How to size a gear motor for swing doors: hinge torque, closer spring load, wind moment, arm ratio and duty limits for compact right-angle AC gear motors.
