Which type of stepper motor requires a specific sequence of current pulses to move the rotor?
A. Permanent magnet stepper motor
B. Variable reluctance stepper motor
C. Hybrid stepper motor
D. Unipolar stepper motor
Answer:D
Which type of stepper motor requires a specific sequence of current pulses to move the rotor?
A. Permanent magnet stepper motor B. Variable reluctance stepper motor C. Hybrid stepper motor D. Unipolar stepper motor
Explanation: Unipolar stepper motors require a specific sequence of current pulses to energize the motor windings and generate the necessary magnetic fields for rotor movement. This sequence determines the direction and speed of rotation.
