Which of the following is a characteristic feature of a bipolar stepper motor?
A. It requires an H-bridge driver circuit
B. It has a higher torque-to-inertia ratio
C. It operates at higher speeds
D. It offers better heat dissipation
Answer:A
Which of the following is a characteristic feature of a bipolar stepper motor?
A. It requires an H-bridge driver circuit B. It has a higher torque-to-inertia ratio C. It operates at higher speeds D. It offers better heat dissipation
Explanation: Bipolar stepper motors require an H-bridge driver circuit to control the current flow and direction in the motor windings. This adds complexity but provides better control over the motor.
