Stepper Motors Operate in Full Steps, Half Steps, and Modified

Multiple Choice

Stepper motors operate in full steps, half steps, and modified half step sequences like the wave drive sequence shown in table 10- 1. The wave drive sequence:

A) has equal torque at all speeds but higher speeds achievable.
B) has more torque than full step sequences.
C) operates stepper motors much more smoothly but consumes up to three times the current.
D) has less torque but operates more smoothly than full step at moderate steps.
