Understanding Stepper Motors
Stepper motors are widely used in various applications due to their precision and control capabilities. Let's break down the assertion and reason provided.
Assertion (A): Stepper motors can be used for speed control.
- Stepper motors are designed to move in discrete steps, allowing precise positioning.
- They can be controlled to vary speed by altering the frequency of command pulses sent to the motor.
- Therefore, this assertion is true.
Reason (R): The motor speed is proportional to the rate of command pulses.
- The rotation speed of a stepper motor directly correlates with the frequency of the input pulses.
- Increasing the pulse rate results in higher speed, while decreasing it slows the motor down.
- Hence, this reason is also true.
Relationship Between A and R
- The reason (R) explains why assertion (A) is true.
- By stating that the motor speed is proportional to the rate of command pulses, it clarifies how stepper motors achieve speed control.
- Thus, R is indeed a correct explanation of A.
Conclusion
Given that both statements are true and that R correctly explains A, the correct answer is option 'A': Both A and R are true, and R is a correct explanation of A.
