Exchange the working principle of stepper motor and split-phase single-phase asynchronous motor, though similar, but the rotor resistance of the former is much larger than the latter, so compared with single asynchronous motor stepper motor, there are three significant characteristics: 1, large starting torque, because of the large rotor resistance compared with ordinary asynchronous motor torque characteristic curve, a significant difference between the two. It can make the critical slip S0 & gt; 1, such not only make torque characteristics (Mechanical properties)Closer to linear, and has a larger starting torque. Therefore, when the stator's a control voltage, rotor rotating immediately, which has the characteristics of starting fast, high sensitivity. 2, 3 with wider range of operation, normal operation of the stepping motor rotation phenomenon, as long as out of control voltage, the motor stop immediately. After losing control of the stepping motor, voltage, it is in single phase operation state, due to the rotor resistance is big, the rotation of the two opposite directions in the stator rotating magnetic field and rotor effect produced by the two torque characteristics (T1 - S1, T2 - S2 curve)As well as the synthesis of torque characteristics (T-s curve)Ac power output of the stepper motor is usually 0. 1 -100W。 When the power supply frequency 50 hz, voltage is 36 v, 110 v, 220, 380 v; When the power supply frequency is 400 hz, the voltage have 20 v, 26 v, 36 v, 115 v, etc. Exchange the smooth operation of the stepping motor, low noise. But control characteristic is nonlinear, and the rotor resistance is big, loss is big, efficiency is low, so compared with dc stepper motor with capacity, big volume, heavy weight, so only applies to 0. 5 -100 w small power control system.
