The difference between two-phase stepper motor and three-phase stepper motor
1. The number of phases of the motor: It means that the number of coils inside the motor is different. The two-phase stepping motor of the mountain machine is composed of two coils, and the three-phase stepping motor is internally composed of three coils.
2. Step angle of the motor: It refers to the angle of the motor every step. Generally, the step angle of the two-phase motor on the market is 0.9°/1.8°, and the three-phase is 0.75°/1.5°. The step angle is 1.8°, and the three-step step angle is 1.2°. It can be subdivided by the corresponding stepper motor driver during actual operation.
3, the size of the motor: Yamashita motor three-phase motor is generally a large motor, so the size is generally larger than the two-phase motor, which also determines that the three-phase stepper motor is more stable than the two-phase operation.
4. Torque: The same size of the two-phase motor of the Yamashita motor will be slightly larger than the three-phase torque.
5. Accuracy: Due to the increasingly powerful subdivision function of the two-phase motor driver of the mountain, the two-phase can also achieve the accuracy that the three-phase can achieve.
The above is the simplest distinction between the two differences, the specific situation should also be treated specifically, the current two-phase stepper motor can replace the three-phase stepper motor produced by many manufacturers in the industry, without special requirements In the case, we recommend that customers use two phases as much as possible.
