This application note describes the design of a 3-phase Permanent Magnet Synchronous Motor (PMSM) vector control drive with 3-shunt current sensing with a position sensor. The design is targeted for automotive applications. This cost-effective solution benefits from a Freescale Semiconductor MPC5604P device dedicated for motor control. The system is designed to drive a 3-phase PM synchronous mo...

Permanent-magnet-synchronous-machine (PMSM) drives have been increasingly applied in a variety of industrial applications which require fast dynamic response and accurate control over wide speed ranges. At the basis of analysis of the mathematical model of the permanent-magnet synchronous motor (PMSM) and the principle of field-orientated vector control, a novel method for modeling and simulink...

Hysteresis motor is self-starting synchronous motor that uses the hysteresis characteristics of magnetic materials to make torque. There are different methods to model this kind of motor and take into account the magnetic hysteresis characteristic of the rotor hysteresis ring. In this investigation the application of complex permeability concept is implemented to model the hysteresis loop and t...

_ Speed control of permanent magnet synchronous motor (PMSM) using Direct Torque Control has rapid response and good static and dynamic performance but less accurate since current, torque and flux linkage wave forms contain big ripples. To overcome these disadvantages stator flux linkage and rotor speed are estimated using Extended Kalman Filter. Therefore, sensorless speed control of surface p...

Motor neuron activity is coordinated by premotor networks into a functional motor pattern by complex patterns of synaptic drive. These patterns combine both the temporal pattern of spikes of the premotor network and the profiles of synaptic strengths (i.e., conductances). Given the complexity of premotor networks in vertebrates, it has been difficult to ascertain the relative contributions of t...

Permanent magnet synchronous motor(PMSM) is a exceedingly efficient motor and is successfully operated in a wide range of speed. Various types of permanent magnet synchronous motors are accessible in the market offering advantages of direct on line starting as induction motor and effectively running on synchronous speed. Major disadvantages of PMSM is uncertainty of successfully synchronization...
