The reason why the stepper motor loses step

What are the reasons for stepper motor to lose step? We mainly analyze products from hardware, software, human and external factors.

In order to find the reason for the stepper motor to lose step, we first judge from the stepper motor body, if the motor selection is improper, it will cause insufficient torque, with immobile load and form lost step; In addition, in the initial stage of motor start-up, due to the initial speed is too high (motor characteristics: high speed and low torque), the acceleration is too large, resulting in small torque and lost step; This can also happen if the speed drops too fast. For the motor that is used for a long time, the temperature of the stepper motor is too high, leading to the demagnetization of the magnetic material of the motor, and it may also be out of step

The second reason for the stepper motor to lose step is the software defect of the driver or human setting or dip error; In addition, interference with the drive or motor is also the cause of stepping motor loss;

The main reason why the power supply causes the stepper motor to lose step is that the voltage is unstable, and if the input current does not reach the rated current, the output torque will decrease, resulting in the loss of step.
