We ever know the operation principle of three-phase hybrid stepping motor is what? Then, Shanghai four macros below the stepper motor simple introduce you: three-phase hybrid stepping motor is usually the three-phase winding connection into a star may be triangle, according to the circuit base theorem, the sum of three phase current is zero. Therefore usually only need two phase winding of a given signal, the third phase winding of a given signal can be obtained by the other two phase. , only need to the corresponding two internship phase winding current sampling, the third internship phase winding current can be obtained according to the type. The IU + + IV IW = 0. Three-phase hybrid subdivision stepper motor drives, system selects the current tracking and pulse width modulation skills, making the phase current of the motor of the phase difference of 120 ° sine wave, power driver circuit chooses six MOS tube, because the three-phase hybrid stepping motor than two phase stepper motor has very good stability at low speed and output torque, so the three-phase hybrid stepping motor than two phase stepper motor has very good prospects, the traditional three-phase hybrid stepping motor control method is based on the hardware comparison is finished, the hybrid three-phase stepper motor using permanent magnetic silicon steel sheet and Japan NSK original bearing production, low carbon environmental protection, torque, compared with other brands stepping motor has high positioning accuracy, high output torque, care of high frequency, low noise, good dynamic performance and other characteristics and advantages. Operation principle of the three-phase hybrid stepping motor is similar to the ac permanent magnet with step by step motor, the rotor on the permanent magnet is used with high magnetic properties of rare earth permanent magnet materials, therefore on the rotor of induced current in the rotor magnetic field can be ignored, the influence of the planning, it is equivalent to a multipolar logarithmic ac permanent magnet synchronous motor, because the input is three-phase sinusoidal current, thus the onset of space magnetic field assumes the circular distribution, and can use planning analysis of permanent magnet synchronous motor torque characteristics of the three-phase hybrid stepping motor. For convenience of analysis, can make the following assumptions: (1)Motor stator three phase winding is completely symmetrical. (2)Magnetic plump, eddy current and the core loss is neglected. (3)No dynamic excitation current care process. 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.
