.The SM2862-5221 is a stepper motor manufactured by Sanyo Denki. This motor has a bipolar winding and a CE/UL Lead wire type. It is controlled by the patented Sanyo Denki Drive Method, which allows precise speed and location control over the motor's angle of rotation. This motor has a high resolution of 0.9° per step and is suitable for use in precision positioning control and precision movement control systems. Additionally, it features a low current ripple, low vibrations, and low noise for quieter operation. It has a rated operating voltage of 3.5 V and a rated current of 2.0 A. The maximum holding torque is 1.7 kgf.cm, and the rotor inertia is 0.37 g·cm2. It also features a built-in Hall Sensor and non-recirculation current characteristics, making it ideal for applications such as robotics, machine tools, medical devices, and automated systems.
