I came around a stepper motor and I'm trying to figure out how to drive it. Currently I'm driving a smaller uni-polar motor with a PIC18F4520 and it's working ok.
The motors specs are:
0.59N.m holding torque
Rated current/Phase (Amps DC) = 2.0A
Phase resistance (ohms) 1.4Ohms
Voltage current/phase (DC) = 2.8VDC
Phase inductance (mH) = 3.
So does this mean that the motor can operate at a max of 2.8VDC and draw 2.0A (2.8VDC/1.4Ohms) per coil ? I'm going to be using the L298 chip and just want to make sure that I don't apply over voltage to the motor. The motor is Bipolar, 2 phase with a step angle of 1.8 degrees.
