The rotational speed of a given stepper motor is determined solely by the
A. Shaft load
B. Step pulse frequency
C. Polarity of stator current
D. Magnitude of stator current.
Answer:B
The rotational speed of a given stepper motor is determined solely by the
A. Shaft load B. Step pulse frequency C. Polarity of stator current D. Magnitude of stator current.
Explanation: The stator part of a motor is the stationary part of the motor and rotational speed of a given stepper motor is given by the step pulse frequency.
