I’m using a Nema23 stepper motor (https://www.pololu.com/product/1472 ) with DRV8825 (https://www.pololu.com/product/2133). I adjusted the current limit of the driver to 0.5A which is half of 1A. My power supply is 12V-2A. The motor runs well, but it gets very hot. I almost burnt my fingertips when I touched the motor while running.
According to the data sheet of the motor, the temp of the motor body could go up 80C, but I’m still worried about the heat. I’m using the motor for an installation and the motor needs to run for 2 weeks without break time.
Do you think it’s fine to run the motor regardless of the heat? Or, is there anything that I can do to cool down the motor? Should I decrease the current limit on the driver?
Any advice would be very helpful.
