Question

Compare the use of servo motors and stepper motors in mechatronics systems.

Answer 1

Ans) Below are the some of the requirements in mechatronic systems where stepper/servo motor is used

SNo	Stepper Motor	Servo Motor
1	Used in systems where high torque density is needed	Used where highest torque-speed range is required
2	Typically runs in open loop operation	Requires closed loop operation
3	Used where high detent torque is needed	Used in systems where highest acceleration/deceleration is needed
4	used where holding at position without hunting is needed	Used where peak torque availability needed is greater than continous torque needed
5	It is easy to integrate than servo sytems	Highest resolution is possible in servo systems
6	Ideal for fixed loads	Highest efficiency and highest product through-put is possible
5	Lower bandwidth than servo systems	High bandwidth response time
