#36891 Easydriver stepper driver class

Posted by Marius on 09 October 2012 - 06:36 PM in General Discussion

Raj, It does not work that way. The motor is rated at 5v continues but you are stepping it so it can handle up to 80v in some cases. Just put the 35v that the drivers can handle on that same motor and you will have the speed. To clarify a bit. The stepper drives makes use of a PWM method of driving the coils of the motor. The PWM is modulated with a sine wave that is rotated or phase shifted as you step the drive. This phase shifting causes the motor to turn. The more micro steps you use the smoother the rotation. Hope this makes some sense to you :)



#36833 Easydriver stepper driver class

Raj The micro step settings will influence the speed but more important is the Motor Voltage. The higher the voltage the more speed you will get. Also if you use steppers with a high coil inductance, the speed will be lower. Th motor will alias much quicker under high step rates. So to summarize: Use motors with low inductance Use the highest possible motor voltage that the driver can handle. Look at your micro stepping settings.
