we can either use dc series motor or induction machine ,but dc supply is not easily available so we use induction motor ,
ac motor
Ac motor has a low starting torque so that DC series motor used in railways cause DC motor has high starting torque
AC voltage controllers are used for controlling the speed of universal motor or induction motor by changing the firing angle :) -vinodh gav
AC Series motors
DC Motor :- SHUNT MOTOR, Series Motor, Compund Motor, ( mainly used in traction system only. as there performanace is very poor & DC supply is not available easily so there uses is less then AC motors,) AC Motor:- Induction Motor ( Slip ring Type, squrrile cage Induction motor) Syncronous Motor.
ac motor
DC Shunt motor
universal motor
stepper motor :- motor used for controlling direction of movement of robotic arm dc motor :- motor used in cellphones as vibrators ac motor :- motor used in textile machinery

AC current is used in motors.
Escalators typically receive their energy from an electrical power source, such as a motor that drives the movement of the stairs. The motor is powered by electricity and converts it into mechanical energy to move the escalator steps.

single phase induction motor
A synchronous motor is used only with a.c. Its speed is dependent on the frequency of the a.c.
An AC Drive used for a speed control of a motor by using vary frequency.
