When the speed of the stepper motor more than it can bear high, locked-rotor phenomenon occurs, for this kind of phenomenon, we can use this way to solve: play a: reduce the highest operating frequency. Blocked in a stepping motor, usually because of excessive speed, so as long as their maximum operation frequency, guarantee the speed within the scope of the motor can withstand, can effectively solve the blocking phenomenon. Method 2: higher deceleration time. Through higher step motor, deceleration time, to avoid the motor in high speed rise suddenly, so as not to appear easily the phenomenon of high speed, which can effectively solve the transfer phenomenon. Three: reduce the starting frequency. When blocked a stepping motor, you start by reducing the frequency, which based on motor speed control, locked-rotor phenomenon. Pattern 4: he scores up a notch. In this way, but also can improve the stepping motor speed more than the maximum of poor performance, after the speed back to normal black achievers, motor stalling phenomenon of nature also disappeared. For stepper motor stalling phenomenon happened, you can use these ways to solve, avoid because appears locked-rotor affect the normal use of the machine. 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.
