Nema 17 Stepper Motor Wiring Diagram

Tips: What is stepper motor?
Stepper motor is an actuator transforming electric pulse into angular displacement. Popularly, when receiving a pulse signal, the stepper motor will rotate a fixed angle (namely ''stepping angle'') according to the direction set for the stepper motor. The angular displacement volume can be controlled by controlling the pulse number to achieve the purpose of positioning accurately. In the meantime, the rotational velocity and acceleration of motor can be controlled by controlling the pulse frequency to achieve the purpose of speed control.

How to test torque for Nema 17 stepper motor?

I’m inquiring how we may be able to test torque for our Nema 17 stepper motor. We are working through a prototype phase of a motor assembly that uses this frame-size motor and needs initial torque readouts. Also, we’d need a measurement tool/device that would help us validate production units that leave our facility. I was initially thinking of a motor dyno but I wasn’t quite sure of the need, compared to a load sensor.
I found what looks to be one solution:
https://www.ato.com/micro-rotary-torque-sensor-5-nm
https://www.ato.com/digital-load-cell-amplifier-output-4-20ma-0-10v-rs485
But I’m looking for your expertise and recommendation for how we may test the various torque measures (holding, pull in/out).
I look forward to your response.

ATO Responded

We also need to confirm the following information before we can provide advice:
1. What are the ranges of torque and rotational speed required to be measured by the Nema 17 stepper motor?
2. What is the torque sensor output signal?
Is it required to measure torque in forward and reverse directions?
