What is the accuracy of the stepper motor? Is it cumulative?

Generally, the accuracy of the stepper motor is 3 to 5% of the step angle. The single step deviation of the stepper motor will not affect the accuracy of the next step, so the accuracy of the stepper motor is not accumulated.

What is the allowable exterior temperature of the stepper motor?

Too high temperature of the stepper motor will first demagnetize the magnetic material of the motor, resulting in torque decrease or even loss. Therefore, the maximum allowable temperature of the motor exterior should depend on the demagnetization point of different motor magnetic materials. Generally speaking, the demagnetization point of magnetic materials is above 130℃, so it is completely normal for the exterior temperature of the stepper motor to be 80 to 90℃.

Precautions

Note
1. The maximum current set by the driver shall not exceed the maximum current of the motor.
2. The subdivision can only adjust the smoothness of rotation, rather than increase the precision.
3. The stepper motor needs to be used with the stepper driver, and cannot be directly connected to the power supply.
4. It is normal if the surface temperature of the stepper motor is between 80~90℃.
