Tips: How to safely operate stepper motors

Whether it is caused by improper operation to damage the stepper motor, or because of improper use, the safety of it is threatened, which will cause huge losses. The stepper motor should be operated safely in the application.

Fully understand the motor: If you want to operate a permanent magnet stepper motor safely, read the instructions and specs carefully before using it, understand all aspects of the motor, clarify how the motor is used, how to switch it on and off.

Operate in accordance with the regulations: maintain the safe operation of the high percision stepper motor, and use the motor in strict accordance with the regulations to ensure the correct operation of all aspects of it, and avoid undesirable consequences and safety problems caused by improper operation or wrong operation.

Safe operation of stepper motors: always pay attention to the condition of the motor, find out and stop the inspection in time when there is an abnormality in the motor, to prevent potential safety hazards due to emergencies, or even accidents.

What is the current required for these stepper motor pulses?

What is usually used to provide the pulse signal for the stepper motor?
I am unsure as to why the Arduino's PWM pins will not work for this application. An Arduino can supply 5V pulses.
What is the current required for these pulses?

ATO Responded

The pulse signal can be sent by a PLC or a single-chip microcomputer.
We have never used the pulse provided by the Arduino you mentioned, so we are not sure whether it can be used.
A pulse is a signal, there is no current required.

Excellent quality.

I used these Nema 34 stepper motors to replace to motors only two of my 3D printers that I have been working to death. They work great now. They’ve been printing non-stop for a few weeks now and have no issues. Excellent quality.

Very satisfied with this stepper motor.

Got this 6.2A Nema 34 stepper motor as a replacement for an old one on my DIY CNC. It has a good torque if provided with appropriate power. I am very satisfied with this closed loop stepping motor and I would buy another as needed.
