These micro gearmotors are extremely durable and come with full - metal gears. With a 30:1 gear ratio, they can operate up to 12 volts. They offer a stall torque of 9 oz - in. and a maximum speed of 900 RPM. Each motor has a 3mm D - shaft. Note that the enclosures for these micro gearmotors are sold separately. You can find them here. Key features include a voltage range of 6 - 12 volts, a 30:1 gear ratio, a stall torque of 4/9 oz - in. (6/12V), a speed of 450/900 RPM (6/12V), a no - load current of 40/120 mA (6/12V), a stall current of 360/1600 mA (6/12V), and they are DC reversible. Dimensions are as follows: motor size is 26 x 12 x 10mm, shaft size is 3mm in diameter and 10mm in length, and it weighs 17g.
Using this micro gearmotor is quite straightforward. First, make sure to connect it to a power source within the 6 - 12V range. Since it's DC reversible, you can control its rotation direction easily. When using, keep in mind that the enclosures are sold separately, so you may need to purchase and install them if needed. As for maintenance, try to keep the motor clean and free from dust. Avoid over - voltage situations as it can damage the motor. If you notice any abnormal noises or a significant drop in performance, it might be time to check the connections or the gears. And remember, the motor is relatively light, so handle it gently during installation and use.
