Whats the diference between Induction motor and servo motor
Answer Posted / narayan jaiswal
Servomotor is ac/dc motor controlled using servo-mechanism. It is negative feed-back controlled (closed loop) using position sensor. It does not rotate continuously but mostly upto 180 degrees. Its speed is reduced (torque increased) by gear mechanism. It is used when precise positioning is needed. General purpose DC servomotors are controlled by PWM signal. Pulse is repeated for every 20ms.
Induction motors rotate continuously as open loop system. There is no feed-back control.The speed may be varied but position cannot be controlled precisely.
