Some users in the use of stepper motor, motor power may be met after such a phenomenon cannot start, this time, the user must be in accordance with the actual conditions of a motor to find out the specific fault reason, and then adopt corresponding method to solve the fault. Specifically, is to ask you to meet this kind of situation, solve the faults of motor like the following: first, for the power supply voltage is too low to stepper motor can't start after the power supply, we should improve the power supply voltage, in order to increase the starting torque of the motor, it can be in the starting torque of motor is large enough, ensure the normal order of the motor can be started. Second, the failure of stepper motor, are also likely to lead to motor can't normal boot after electricity, in the presence of this aspect, we should check the motor of motor stator, rotor winding broken, short, by means of relevant structural part to check, find the cause of the problem, and then determine the appropriate solution. Third, if there is a stepper motor control device failure, caused by the motor power to start, we should examine the output voltage and current of the excitation device is normal, by doing corresponding processing ensure the normal order of the status and function of the control device, and start to make the motor back to normal. 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.
