The SH1421-5211 is a low-cost stepper motor manufactured by Sanyo Denki. It is a typical bipolar winding, 4-lead wire type stepper motor. The driver/controller is compatible with a wide range of input voltages (between 3 and 24 V DC), and it can deliver up to 25W of continuous power. This motor is designed to make precise, fast, and silent low-speed rotations. It is ideal for applications that require precise, low-speed positioning such as robotics, printing systems, and medical equipment. This motor also features high torque at low speeds and minimal vibration and noise. It is rated for operation at temperatures up to 50°C (122°F).
