Abstract :
This paper investigates the performances of an interior permanent magnet synchronous motor (IPMSM) drive over wide speed range for high precision industrial applications. The scheme incorporates the maximum torque per ampere (MTPA) operation in constant torque region and the flux-weakening operation in constant power region. The power capacities of the motor and the inverter are also considered. The efficacy of the above mentioned drive system is evaluated by both experimental and computer simulation results
