Descrição

156:1 Metal Gearmotor 20Dx44L mm 6V

These cylindrical brushed DC gearmotors are available in a wide range of gear ratios, from 25:1 up to 488:1, and they are optionally available with an additional 2 mm-diameter output shaft that protrudes 6 mm from the rear of the motor. This optional rear shaft rotates at the same speed as the input to the gearbox and offers a way to add an encoder, such as our magnetic encoder for 20D mm metal gearmotors, to provide motor speed or position feedback.

20D mm metal gearmotor (without extended motor shaft).

20D mm metal gearmotor with extended motor shaft.

The gearmotors all have 20 mm-diameter gearboxes and 4 mm-diameter gearbox output shafts, so it is generally easy to swap one version for another if your design requirements change (though the length of the gearbox tends to increase with the gear ratio). Please see the 20D mm metal gearmotor comparison table for detailed specifications of all our 20D mm metal gearmotors. This dynamically-sortable table can help you find the gearmotor that offers the best blend of speed, torque, and current-draw for your particular application.

Note: Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. For these gearboxes, the recommended upper limit for instantaneous torque is 125 oz-in (9 kg-cm); we strongly advise keeping applied loads well under this limit. Stalls can also result in rapid (potentially on the order of seconds) thermal damage to the motor windings and brushes, especially for the versions that use high-power (HP) motors; a general recommendation for brushed DC motor operation is 25% or less of the stall current.

These motors are intended for operation at around 6 V. In general, these kinds of motors can run at voltages above and below their nominal voltages; lower voltages might not be practical, and higher voltages could start negatively affecting the life of the motor.
