In the operation of modern power work, step motor is widely used, so the study of the invention is more also. On its type, according to the different ways, can be divided into different types. This article is mainly to introduce according to the different excitation type two kinds of different step motor, is how to have the same effect. 1, the electric excitation stepper motor, the motor rotor is the salient pole type. Because is in series between the electromagnetic coil, at the time of contact will be alternating contrary model, which requires the two root wire connected to the slip ring. Field coil is to use a small battery for intense work. But the motor does not start automatically, can cause to a certain problems in the production process. 2, permanent magnet stepper motor, the motor rotor excitation effect does not occur, in the use of multiphase power will be able to get a better application. So this is a salient pole rotor, the rotor in the process of running but still able to maintain a certain magnetism. Even the torque of the motor rotate at a certain speed, the salient pole rotor and stator coil can also achieve the result of step by step. Its number and number of the upper pole of the stator is basically consistent, is to maintain balance. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
