Description
Measuring 37 mm (1.46″) in diameter, these brushed DC gearmotors are the largest and most powerful we carry. They are available in a range of gear ratios from 6.25:1 to 810:1 and with 6 V or 12 V or 24 V motors, and all versions are available with integrated 64 CPR quadrature encoders on the motor shafts. The gearbox is mainly composed of spur gears, these units have a 16 mm-long, 6 mm-diameter D-shaped output shaft.
Specifications
- The first specification: 12V voltage metal DC geared motor, this series of motors are compatible with 6V voltage at the same time;
- The second specification: 24V voltage metal DC geared motor;
- The third specification: 12V voltage metal DC gear motor with encoder, this series of motors are compatible with 6V voltage at the same time;
- The fourth specification: 24V voltage metal DC geared motor with encoder.
Note: The listed stall torques and currents are theoretical extrapolations; units will typically stall well before these points as the motors heat up. Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. The recommended upper limit for continuously applied loads is 10 kg-cm (150 oz-in), and the recommended upper limit for instantaneous torque is 25 kg-cm (350 oz-in). Stalls can also result in rapid (potentially on the order of seconds) thermal damage to the motor windings and brushes; a general recommendation for brushed DC motor operation is 25% or less of the stall current.
