Answer to Question 1

A

Answer to Question 2

A stepper motor is used as the drive mechanism for many types of rotary and linear solar panel access control systems. Stepper motors provide a means for precise positioning. The stepper motor has the ability to move its shaft in very small increments so that it can provide movements that are very precise.
