1. Stepping planetary gear motor phase number refers to the inside of the motor coil group number, at present there are two phase, three-phase, four commonly used phase, five phase stepper planetary gear motor. Step motor phase number is different, the pitch Angle is different, the general step of the two-phase motor from the Angle of 1. 8 degrees, three phase 1. 5 to 0 degrees, five phase. 72 degrees. When no subdivision driver, user mainly by choose the number of different phase stepping motor to satisfy the requirement of interval Angle. If using subdivision driver, phase number will become meaningless, users only need to change the fine fraction on drives, can change interval Angle.

2. Two phase stepper motor only two on the stator winding, has four stages, the step 1. 8° , half step is 0. 9° 。 As long as in the drive for two phase winding electric current and current direction control.

3. Stepper motor is not like ordinary dc motor, ac motor under normal use. It must be driven by double annular pulse signal and power circuit of control system can use. So good with step motor is not easy, it involves the mechanical, electrical, electronic and computer and many other professional knowledge.

4. Stepper motor is the electrical pulse signal into angular displacement or line open loop control elements of displacement. In the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, which give the motor a pulse signal, a step from the Angle of planetary gear motor is turning. This line sexual relations, and the error of the stepper motor only periodic without cumulative error, etc. Made in the field of speed and position control with stepper motor to control becomes very simple.

5. Stepper motor is applied to low speed situation, RPM is not more than 1000 turn, and in 1000 - best Use between 3000 PPS, can through the reduction gear to make it work here, the motor work with high efficiency, low noise. Step step had better not use the whole state, the whole state of vibration.
