What are the different applications of two-phase and five phase hybrid stepping motors?
Problem solution:Generally speaking, two-phase motors have large stepping angle and high speed characteristics, but there is a low speed vibration zone. But the five phase motor has a small step angle and a low speed running smoothly. Therefore, higher requirements on the accuracy of the motor running in, and mainly in the low speed (typically below 600 rpm) occasions should be used in five phase motor
Compared with stepper motor, servo motor has the following advantages:1, the closed loop control of position, speed and torque is realized, and the step of stepping motor is overcomeProblems;2, high speed performance, generally rated speed can reach 2000~3000 rpm;3 、 strong overload resistance, can withstand three times the rated torque load, especially for occasions with momentary load fluctuations and rapid start;4, low speed running smoothly, low-speed operation will not produce stepper motor similar step operation. Suitable for occasions where high speed response is required;5, the motor acceleration and deceleration of the corresponding short time, usually within a few milliseconds, 6, heating and noise decreased significantly.
On the other hand, if the pursuit of high speed motor performance, the accuracy and stability of the absence of much demand for occasions, should choose a lower cost two-phase motor. In addition, the torque of the five phase motor is usually more than 2NM, and the two-phase motor is used in the application of the small torque, and the problem of low speed stability can be solved by using a subdivision drive.
