Micro Stepper Motors

ATO provides Nema 4, Nema 6, Nema 8, Nema 10, Nema 14 and Nema 17 micro stepper motors for sale. Micro stepper motor is a miniature bipolar stepper motor, which is different from a unipolar motor. Stepping angles are 7.5 degree, 15 degree and 18 degree. You can buy 2-phase or 4-phase micro stepper motor online, high quality, miniature size, high torque and affordable price.

Difference between 2 phase and 4 phase micro stepper motor

• Phase. The Phase means that the number of coils inside the motor. The 4 phase stepper motor is composed of two coils, while the 4 phase stepper motor is composed of three coils.
• Steping angle. Stepping angle refers to the angle of each step of the stepper motor. Generally, the step angle of the 2 phase motor is 0.9°or 1.8°, and the 4 phase motor is 0.75° or 1.5°.
• Dimensions. 4 phase micro stepper motors are generally large motors, so the size is generally larger than that 2 phase motors. Therefore, 4 phase stepper motors run more smoothly than 2 phase motors.
• Torque. The torque of the two phase stepper motor will be slightly larger than the torque of the three phase motor with the same size.
• Accuracy. The 4 phase stepper motor has high-speed performance, smaller step angle and better accuracy than the 2 phase stepper motor. Since the torque decreases slowly with the increase of speed, it is usually used in occasions where high precision is required.
