Description N20 DC Gear Motor with Hall Encoder - Metal Gearbox
This N20 DC gear motor is a compact 12V DC reduction motor with a metal gearbox and a magnetic Hall encoder. This makes it suitable for projects where you not only want to rotate, but also want to know how far and how fast the motor rotates. Think of small robots, automation, smart devices, and mechanical prototypes.
The motor has a reduction ratio of 1:150. This provides more torque and better control at low speeds. The no-load speed is 200 rpm. The stall torque is ≥ 1.2 kg.cm. This makes it suitable for light drives, valves, slides, and small transmissions. The motor starts at a low voltage (no-load starting voltage max. 3.0V), but is designed for 12V as the nominal voltage.
The built-in encoder is an AB dual-phase (quadrature) Hall encoder. This provides two signals (A and B) with which you can measure direction and speed. The encoder operates on 3.3V or 5V and has pull-up resistors, allowing you to connect it directly to a microcontroller. The base resolution is 7 PPR, and due to the gear ratio, this results in 1050 PPR (7 × 150). This provides finer feedback than motors without an encoder, especially during slow movements.
Connection is neatly made via the L-shaped 6-pin connector (ZH1.5-6PIN). This is convenient if you build the motor into a compact housing. Thanks to the metal gears, the gearbox is stiffer and more durable than plastic variants. This contributes to repeatability and long-term use.
