Application characteristics of permanent magnet synchronous and brushless DC motors for servo drives Abstract: The permanent magnet synchronous motor PMSM and the brushless DC motor BDCM have many similarities; they both have permanent magnets on the rotor and require alternating stator currents to produce constant torque. For application considerations, these two motor drives have to be differentiated on the basis of known engineering criteria.
Par brown donald le vendredi, mai 20 , - Lien permanent. Download eBook. There are basically two types of synchronous motors: self synchronous motor may be called by various names. Apr 14 For more information on TI's complete motor drive and control portfolio visit www. However, recent advances in power control circuitry have given rise to synchronous motor designs optimized for use in such higher power situations as fans, blowers, and to drive axles in off-road vehicles. The classic DC motor design generates an oscillating current in a wound rotor, or armature, with a split ring commutator, and either a wound or permanent magnet stator.
Despite two decades of massive strides in research and development on control strategies and their subsequent implementation, most books on permanent.
Despite two decades of massive strides in research and development on control strategies and their subsequent implementation, most books on permanent magnet motor drives still focus primarily on motor design, providing only elementary coverage of control and converters. Addressing that gap with information that has largely been disseminated only in journals and at conferences, Permanent Magnet Synchronous and Brushless DC Motor Drives is a long-awaited comprehensive overview of power electronic converters for permanent magnet synchronous machines and control strategies for variable-speed operation. It introduces machines, power devices, inverters, and control, and addresses modeling, implementation, control strategies, and flux weakening operations, as well as parameter sensitivity, and rotor position sensorless control.

Permanent magnet brushless DC PMBLDC motors are the latest choice of researchers due to their high efficiency, silent operation, compact size, high reliability and low maintenance requirements. These motors are preferred for numerous applications; however, most of them require sensorless control of these motors. The sensorless control would need estimation of rotor position from the voltage and current signals, which are easily sensed. Download PDF. Article Info. Abstract Permanent magnet brushless DC PMBLDC motors are the latest choice of researchers due to their high efficiency, silent operation, compact size, high reliability and low maintenance requirements.
Documentation Help Center Documentation. This drive features closed-loop speed control through stator current control, using Hall sensors. The speed control loop outputs the reference electromagnetic torque of the machine. The reference stator phase currents corresponding to the commanded torque are derived based on the machine torque constant and the Hall sensor signals.
