Pmsm And Bldc Sensorless Motor Control Using The 56f8013 Device

   This manual describes the design of a 3-phase Permanent Magnet Synchronous Motor (PMSM)
sensorless vector control drive and a Brushless DC (BLDC) Motor drive without postiion encoder
coupled to the motor shaft. It uses a Freescale 56F8013 with Processor Expert
TM (PE) software support.
A PMSM consists of a magnetic rotor and wound stator construction. Its wound stators CAN rapidly
dissipate heat to the motor housing and environment. In contrast, a brush motor traps the heat under a
non-conductive air gap, resulting in greater efficiency and power density for the PMSM design and
providing high torque-to-inertia ratios. A PMSM motor generates magnetic flux using permanent
magnets in the rotors, which are driven by the stators applying a synchronous rotational field. On the
other hand, the flux that is applied by the stators (the armature-reaction flux) generates torque most
effectively when it is perpendicular to flux generated by the rotors. To maintain near-perpendicularity
between stator flux and rotor flux, two control methods with position-speed feedback loop are popularly
used for controlling a PMSM: Field-Oriented Control and Brushless DC Control.  3.3.1.2   56F8013 BR>The PMSM’s performance and accurate control demands require sophisticated and computationally
complex software, delivered by a powerful DSC like the 56F8013.
