Roll no

1. Name the factor determines the step angle of a stepper motor

• Motor voltage
• Number of windings
• Rotor inertia
• Number of rotor teeth and stator poles

2. Identify the application would a stepper motor be most suitable

• High-speed continuous rotation
• Variable-speed operation
• High-torque lifting
• Continuous linear motion

3. identify the type of feedback mechanism is commonly used in servo motor control systems

• Voltage feedback
