Selecting a gear motor for your mechanism
A gear motor combines a motor and reduction gearbox to provide an output suited to wheels, small mechanisms and robotics projects. Compare the actual output specifications and mounting details; motors with similar housings can have different gear ratios.
- Choose output RPM for the required movement speed.
- Check rated torque, duty cycle and allowable load where specified.
- Verify shaft shape, diameter and coupling compatibility.
- Size the supply and controller for motor current, including starting conditions.
Browse wheels and motor couplings for mechanical connections, motor drivers for control, or mini motors when a gearbox is not required. A listed motor’s ratings should determine the design, not the category name alone.
