Power
- At 6V, the stepper will have V=IR=6=I*7.5 - so I=0.8A per phase. Period. Power is IV = 0.8*6V=4.8.
- Note power is double: there are 2 phases. So 9.6Watts.
- Note power is not determined by provided voltage - such as 24V. The formula refers to the voltage that is actually used. By limiting current, we can reduce power use.
