The escalator is a moving belt in big shops and other places.Escalator consists of synchronous motor because synchronous motor does not depends on load up to certain limit,that is the load angle.if the load angle is reached above 90 degrees the motor comes out from synchronization due to the loss of sychronism motor stops. Because of synchronism every escalator has some people(load) limit.
