Product Description
Description
This is the motor and encoder portion of our 12V 37D mm metal gearmotors with 64 CPR encoders. It does not include a gearbox, but the pinion gear on the output shaft works with all of our helical pinion 37D mm gearmotor gearboxes, so this can be used as a replacement motor or encoder for those gearboxes.
Features
This motor with integrated 64 CPR (counts per revolution) quadrature encoder is intended as a replacement motor and encoder for our 37D mm metal gearmotors with helical pinion gears.
The 2mm output shaft has a non-removable pinion gear that works with all of our “Helical Pinion” 37D mm gearmotor gearboxes. Note that we do not sell the 37D mm gearboxes separately, but if you have a gearmotor with a damaged motor or encoder (or if you want to effectively add an encoder to a version without an encoder), you can transfer the gearbox to this replacement motor.
The motor has a diameter of 34.5 mm (1.36 in) and a length of approximately 44 mm (1.7 in) from the top of the motor can to the bottom of the encoder. The top of the motor has six mounting holes evenly spaced around the outer edge threaded for M2.5 screws. These mounting holes form a regular hexagon, with the center of each hole located 13 mm from the center of the output shaft. The mounting holes have a depth of approximately 3.5 mm.
Key specifications
- voltage: 12 V
- no-load performance: 10,000 RPM, 200 mA
- stall extrapolation:0.5 kg·cm (7 oz·in), 5.5 A
Dimensions
- Size:34.5D × 46.5L mm(Length measurement does not include motor shaft or pinion gear.)
- Weight:110g
General specifications
- Gear ratio: 1:1(This motor does not have a gearbox.)
- No-load speed @ 12V: 10000 rpm
- No-load current @ 12V: 0.2 A
- Stall current @ 12V: 5.5 A
- Stall torque @ 12V: 0.5 kg·cm(Stalling can damage the motor. Stall parameters come from a theoretical extrapolation of performance at loads far from stall. As the motor heats up, as happens as it approaches an actual stall, the stall torque and current decrease.)

- No-load current @ 6V: 0.15 A
- Stall current @ 6V: 3.0 A
- Stall torque @ 6V: 0.3 kg·cm(This motor will run at 6 V but is intended for operation at 12 V.)
- Motor type: 12V
- Lead length: 20 cm(May vary by a few centimeters.)
- Encoders?: Y
- Encoder resolution: 64 CPR
