This paper presents the speed estimation of permanent magnet synchronous motor (PMSM) without sensor.Efforts are kept to eliminate mechanical sensor for speed estimation. Use of speed sensor increases the cost and also themaintenance of PMSM. The technique used for estimation of speed is Model Reference Adaptive System (MRAS). Thespeed estimation is done for constant speed drive. The estimated speed is independent on stator resistance (Rs) and isonly dependent on q-axis stator inductance (Lq) of motor. The reference and adjustable model equations used are simpleand less computation is required. Vector control strategy is used for speed control of PMSM. Online estimation of rotorspeed is possible by implementing the scheme presented in this paper.
