Established in 1992, China Qiangjin Power Co., Ltd. is a professional gearmotor manufacturer and dealer of in the emergency power supply industry. We not only specialize in manufacturing different kinds of generators, but also in motors, engines, diesels, gearmotors and other power supply products. Now, our OEM gearmotors products are exported to North America, Europe(UK, France, Germany, Italy), USA, Japan and Canda. Our company has obtained the certifications of ISO9001-2000, GS/TUV, CE, VL, EPA, QHS, SON, CAP and SRS.

Brushless motor for high torque, smaller size, and no maintenance. Industrial lip type seals on motor and output shafts. Needle bearings on output shaft for increased radial load capacity and long life. Permanently lubricated gearing utilizing semi-fluid grease for long life. Bronze gear for high shock load capability. Hardened and ground worm for high strength and long life. Brushless motors require a control. Performance ratings of 115° C winding, 25° C ambient, and no heat sink. Mounting holes are on gearhousing.
This motor is a metal drive motor which is perfect for a differential drive motor in your project. It is not brand new but is unused surplus. It has an approx. 1/8" (2.5mm) output shaft driven by four stages of metal gears. It also features a convenient mounting plate for ease of mounting the motor to your robot.

These 24VDC Type 02 52mm diameter gear motors are made with steel gears (not plastic or sintered metal). They are real stout motors. They weigh about 2.5lbs each. We sampled many other manufactures and the gears would strip or the windings would burn up, we had no failures with these.
We recommend controlling the motors with one of our motor speed controllers. See our motor controller support page for more information. We also recommend you use our wiring kit to wire your motors to control the electronic noise generated from any DC motor. See our motor wiring support page for more information.
The table below lists its characteristics. The datasheet images below show the current and torque curves and the gear motor's dimensions. These motors have a stall torque of 150 kgf-cm! They utilize a 1:19 gear reduction. The gear motor is 24VDC.
