This is a quality pack for indoor robots, especially our Home Care Robot platform, and comes with a 12V Low noise DC Motor 146RPM, Encoder and Rubber Wheel 136×24mm (Pair).

12V Low noise DC Motor 146RPM w/Encoder

One of our favourite customized high-quality DC motors. Low noise, high torque output with optical encoder built-in.  The optical encoder gives 663 pulses per rotation which is able to sense 0.54-degree rotation from the shaft.  This resolution meets general PID speed control requirements thus making it a great choice for robotics. The sturdy metal casing, and gears give you a chance at a competition robot or harsh environments where your robot might get hit by objects or people. This motor is widely used in mobile robot areas and some stationary automation devices. The optical encoder is based on a plastic top easily accessible, and with the included cable you can easily get it connected to your device.

Rubber Wheel 136×24mm (Pair)

After testing more than 6 different rubbers on the carpet, wood surface, marble surface, and glass surface, we finally formed this tyre with proper softness and tyre surface design. The dent on the tyre plays a good anti-slip effect and provides a firm grasp over the moving surface. Far better than any other tyres in the market. It has been widely used on our HCR mobile robot platforms.

Note: If the bearing hole is loose during the installation process, adhesive tape can be applied to the motor shaft plane to increase the friction between the motor and the coupling, ensuring a tight lock.
