Stepper Nema 17



Product Description

The Mosaic stepper motor (part no. STEPMOT-1) is a four phase, unipolar, permanent magnet stepper motor. It is a standard size, 200-steps-per-revolution, NEMA 17 (1.7 in. square footprint, 5 mm shaft diameter), 12 V motor. This motor, like most stepper motors is a permanent magnet motor. The Mosaic stepper is typical of common high resolution motors – a full revolution requires 200 steps, while each step turns the shaft only 1.8° for a full step, or 0.9° in half-stepping mode. This sized motor is commonly used in household appliances, medical equipment, stage lighting devices, and in various industrial control applications.

The following are the specifications of the motor:
