DESCRIPTION
This tiny, sub-micro plastic planetary gearmotor consists of a coreless brushed DC motor and a 700:1 plastic planetary gearbox. The entire assembly has a diameter of just 6 mm (0.24″) and is extremely lightweight at 1.3 g (0.046 oz), making it a great actuator for miniature robots and very small mechanisms. It can achieve 90 RPM at 6V.
These tiny brushed DC gearmotors have a diameter of just 6 mm and weigh just over a gram, which makes them great actuators for miniature robots and very small mechanisms. They consist of a coreless motor fastened to a planetary gearbox by a small clip. The gears are made from liquid crystal polymers (LCPs).
The intended nominal operating voltage for these motors is 3 V to 6 V, though in general, these kinds of motors can be used at voltages outside this range (rotation typically starts between 0.2 V and 0.3 V). Lower voltages might not be practical, and higher voltages could start negatively affecting the life of the motor. When operating at 3 V, the free-run speed, stall torque, and stall current will all be approximately half of what they are at 6 V as these specifications scale roughly linearly with voltage.
Please 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 3.5 oz-in (250 g-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; a general recommendation for brushed DC motor operation is 25% or less of the stall current.
- Since the gearmotors output shaft is nylon, there can be small variances in the diameter from unit to unit.
