robotics - How stepper motor torque will behave for two different supply, 24v/5A and 36v/5A

Question

How stepper motor torque will behave for two different supply, 24v/5A and 36v/5A. I am using three Nema 23 , 10kg-cm stepper motors. Using TB6600 Driver which will limit my current to rated current from the supply. It accepts 12-36v and 2.8 is the rated current.

I want to achieve max torque. I went through T depends on Current. What is my motor torque behavior, when 24v/5A, 36v/5A. Speed will be very less in my use case - kind of robitics arm.

Answer 1

如果 TB6600 将电机电流限制为 2.8A，那么任何能够提供超过 2.8A 电流的电源的扭矩都是相同的。

在内部，我希望 TB6600 使用斩波器驱动器来限制总平均电流 -来自https://www.linearmotiontips.com/what-is-a-chopper-drive-for-a-stepper-motor/的斩波器驱动器波形

因此，如果您增加提供给驱动器的电压，您可能会看到转矩脉动频率增加，但平均转矩仍将相同。
