ALAC Stepper Motor Drive Modes Questions

please answer the rest of the questions:

3. Explain how the following stepper motor drive modes can drive a motor with the help of their state tables and timing diagrams a. Wave drive b. Full step drive c. Half step drive

4. What is torque ripple?

5. Explain how driving a stepper motor in half‐step mode causes torque ripple

6. Explain what micro‐stepping is and what advantage it can provide compared to full step drive?

7. Explain the purpose of a gear reduction system found within a motor encasing.

8. If the resolution of a motor is listed to be 0.9°/step, how many steps would it take the motor to complete a full revolution?

9. What is the main difference between the components of a motor called a stator and a rotor?

10. If an unknown motor has 4 wires then would it likely be a unipolar or bipolar motor?
