Stepper motor are fixed resonance region, two, four phase induction of resonance type stepping motor area is in commonly 180 -PPS (250Step away from the Angle of 1. 8 degrees)Or around 400 PPS (Step away from the Angle of 0. 9 degrees), the higher the motor driving voltage, electric current, the greater the load is light, the motor volume is smaller, the resonance region upward migration, and vice versa, in order to make the motor output electric moment is big, do not break step and the noise of the whole system is reduced, the general working point shall be offset resonance region. 8, motor and reversing control: when the electric motor winding timing for AB -BC -CD -DA or ()As a forward, timing for DA - current is switched onCA-BC -AB or ()For reversal. Three, drive control system of use, control stepping motor must by annular pulse, power amplifier, etc of the control system, its block diagram is as follows: 1, the generation of the pulse signal. The pulse signal generated by the microcontroller or CPU commonly, general pulse signal of the duty ratio is 0. 3 -0. About 4, motor speed is higher, the duty ratio is bigger. 2, signal distributor,Also known as pulse distributor)Hybrid stepping motor with two, four phase is given priority to, two-phase motor works have two phase two, four taps and two phase eight specific distribution is as follows: four shoot for two phase, step away from the Angle of 1. 8 degrees; Step eight clap for two phase, from the Angle of 0. 9 degrees. Four phase motor works also have two, four shoot for AB - four phaseBC -CD -DA-AB, step pitch Angle of 1. 8 degrees; Take for AB - four phase eightB -BC -C -CD -D -AB,(Step away from the Angle of 0. 9 degrees)。 3, power amplifier, power amplifier is the most important part of the drive system. Stepper motor under a certain speed torque depends on the average current dynamic rather than static current (The samples are on the current static current)。 The bigger the average current of motor torque, to achieve an average current big which requires motor drive system to overcome the potential. Take different drivers and different occasions, so far, drive mode usually has the following kinds: constant pressure and constant pressure series resistance, high and low pressure drive, constant current and fine fraction. As far as possible to improve the dynamic performance of motor, the signal distribution, power amplification of stepper motor driver power supply. Description: stepper motor once finalize the design, its performance depends on the motor drive power supply. The higher the stepper motor speed, torque, the greater the demands of the motor current, the greater the drive power supply voltage is higher. 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.
