Description
- Pololu MP 12V Motor w/ 48 CPR Encoder for 25D mm Metal Gearmotors (No Gearbox)
- Replacement part for Pololu
- Measures 24.2 mm diameter and 43 mm length
- Features a 48 CPR quadrature encoder
The Pololu MP 12V Motor w/ 48 CPR Encoder for 25D mm Metal Gearmotors (No Gearbox) is a versatile replacement component designed for medium-power applications. This motor features an integrated 48 CPR quadrature encoder, providing precise rotational feedback with 48 counts per revolution. It is compatible with all 25D mm gearmotor gearboxes, though the gearbox itself is not included. Constructed with a durable 24.2 mm diameter and a length of approximately 43 mm, the motor includes a non-removable pinion gear and two M3 threaded mounting holes spaced 17 mm apart. Operating optimally at 12 V, the motor achieves a no-load performance of 8200 RPM at 100 mA and a stall torque of 0.17 kg⋅cm. The encoder utilizes a two-channel Hall effect sensor, requiring an input voltage between 3.5 and 20 V, and offers flexible connectivity with six color-coded leads. This component is ideal for those seeking to replace a damaged motor or add encoder functionality to existing gearmotor assemblies.
