With the wire rod, can appear in the use of high-speed step and stall, not up to the requirements, the motor model 85BYGH450A-02 1.8 step force from 2.1 current 3A driver model DL-023MDC adjustable current range 0.45~3.15A is supporting the use of high-speed, now can run there I, for a driver DMD808A can not complete high-speed operation, please help me master the analysis is what causes, thank you very much.
What is the reason that the stepper motor can not operate at high speed?:If this happens the voltage and current under normal circumstances, should problems arise in the driver, because the step phenomenon usually appears in the drive frequency exceeds a set range of the motor itself
Number of pulses can be controlled by controlling the angular displacement, so as to achieve the purpose of accurate positioning; at the same time by controlling the pulse frequency to control the motor rotation speed and acceleration, so as to achieve the purpose of speed. Stepper motor can be used as a special motor for control. It is widely used in all kinds of open-loop control without the accumulation of error (accuracy 100%).Now more commonly used stepper motor, including reactive stepping motor (VR), permanent magnet stepper motor (PM), hybrid stepping motor (HB) and single-phase stepper motor.
In this way, the motor's original step angle has not been completed, so the next action must be done according to the driving force! Stepping motor is an actuator that transforms electric pulse into angular displacement. When the stepper driver receives a pulse signal parameters, it drives stepper motor stepper motor to set the direction of rotation of a fixed angle (called "step"), it is the rotation of the fixed point of the operation step by step.
