What is a stepper motor?
A motor that requires feedback sensors for positioning
A brushless DC motor that rotates in steps
A motor that rotates continuously without steps
A motor that uses brushes for operation
What is the main advantage of a stepper motor?
It requires feedback sensors for precise positioning
It is cheaper than other motors
It can be precisely positioned without feedback sensors
It operates at very high speeds
What is the Wave Drive mode?
A mode where all coils are activated simultaneously
A mode where one coil is activated at a time
A mode that uses a sine wave for coil activation
A mode where two coils are activated at a time
Which driving mode provides the highest torque output?
Wave Drive
Microstepping
Full Step Drive
Half Step Drive
How does the Half Step Drive mode increase resolution?
By increasing the number of rotor poles
By using a sine wave for coil activation
By using a combination of one and two active coils
By activating all coils at once
What is Microstepping?
A mode that increases the number of rotor poles
A mode that uses a permanent magnet rotor
A mode that activates all coils simultaneously
A mode that uses a sine wave for coil activation
Which type of stepper motor has a permanent magnet rotor?
Variable Reluctance Stepper
All of the above
Hybrid Synchronous Stepper
Permanent Magnet Stepper
What is unique about the Variable Reluctance Stepper motor?
It uses a sine wave for coil activation

What is a characteristic of the Hybrid Synchronous Stepper motor?
It uses a sine wave for coil activation
It combines features of permanent magnet and variable reluctance steppers
It has a non-magnetized rotor
It has no teeth on the rotor
How many poles does a commonly used hybrid stepper motor have on the stator?
4 poles
6 poles
8 poles
10 poles
What happens when winding A is activated in a hybrid stepper motor?
The rotor stops moving
Four poles are magnetized with alternating polarities
The rotor moves clockwise
All poles are magnetized with the same polarity
What is the result of activating poles in a particular order in a stepper motor?
The rotor moves randomly
The rotor moves continuously
The rotor stops moving
The rotor moves in reverse
Which driving mode is most common for controlling stepper motors today?
Wave Drive
Full Step Drive
Half Step Drive
Microstepping
What is one way to increase the resolution of a stepper motor?
Use a single coil activation
Increase the number of stator poles
Use a permanent magnet rotor
Decrease the number of rotor poles
What is the role of the stator in a stepper motor?
To create electromagnetic poles for propulsion
To rotate the motor continuously
To decrease the motor's resolution
To provide feedback for positioning
