I was just about to ask the same question as well... Sorry everyone if this sounds like a very simple question, but my motor's datasheet states that it is rated at 1A/phase. I did some additional research online and read that this means the max RMS current each phase can take is 1A. Because this is a 2 phase motor, does this mean that my power supply current should be 2 A? Is there a problem with using a power supply with current output which is significantly higher e.g. 2 times higher than the rated current of the motor?
I'm not too sure about the terminology here but is it better to run the motor with a supply current slightly below 2A (to avoid frying them), or to give them 1-2 A above the motor's rated current?
