As useful as stepper motors are, they have a number of clear disadvantages, not the least of which is their constant current draw. As there is no mechanical mechanism to hold the stator in place ...

Stepper motors typically run hot because there is multiple ... there are drivers that will reduce the current draw during periods of inactivity. The Geckodrive GM215 driver at left has this ...

However, a stepper motor is limited by heat generation ... A larger mismatch will cause the motor to lose pulses, miss position, draw excessive current, or even stall. Tips 7 and 8 courtesy ...
