MotorsQuestion 1228 of 1506

Why does full step drive give more torque than wave drive?

  1. Only a single winding carries current at any moment.
  2. The supply voltage is doubled in full step mode.
  3. Both windings carry current together.
  4. The rotor is a different type in full step mode.
Show answer

Correct answer: Both windings carry current together.

In wave drive just one winding is on, so the field is weaker.
