Stepper motor has a technical parameters: no-load start frequency, the stepper motor under no-load condition can normal boot pulse frequency, if the pulse frequency is higher than the value, the motor does not start properly, may be lost or blocked. In the load cases, start frequency should be lower. If you want to make the motor to achieve high-speed rotation, the pulse frequency should be to accelerate the process, namely the start frequency is low, and then in a certain high frequency acceleration to want (Motor speed from low speed to high speed)。 Stepper motor is the electrical pulse signal into angular displacement or linear displacement of open loop control stepping motor. 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, when the stepper motor driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed point of view, called & other; Interval Angle & throughout; , its rotation is based on the Angle of the fixed step by step. Can be controlled by controlling the pulse number of angular displacement, so as to achieve the purpose of accurate positioning; As well as by controlling the pulse frequency to control motor rotation speed and acceleration, so as to achieve the purpose of regulating. The acceleration of the acceleration of PLC control for the slope, commonly used time from 100 to 500 milliseconds, the acceleration of single chip microcomputer process can make the curve, the curve speed more smoothly, the same conditions than the slope to reach a higher maximum speed, stepping motor from high-speed to stop also must have a slow process, otherwise it will lead to overshoot stepper motor, and suddenly the wager transfer damage stepper motor drives. In addition, above a certain speed can't start sometimes accompanied by whistlers, producing whistlers may be caused by heavy load and high speed when the motor output torque is reduced, unable to meet the requirements of the load when the motor is blocked in turn, and whistlers will changes with the frequency of high and low, the solution is to reduce speed or replace a bigger torque motor. In addition will be shown after the step motor running at high speed to stop short of whistlers, this is caused by the phase current chopping, just put the drive panel automatically half flow is set to be valid. 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.
