In order to solve the existing permanent magnet synchronous motor starting from starting performance and energy target fight between rotor and limited space of conflict. The line-start permanent magnet synchronous motor with the special structure of the disk magnet polyed magnetic type has been proposed. Motor rotor punching trough, size, and cast aluminum material can give full consideration to the requirements of line-start function in the new type of permanent magnet synchronous motor. polymer magnets which is formed from alternating magnetic yokes and permanent magnetic ring is set between the hinge and the rotor part; Interval set on the outer circle of magnetic yoke take the magnetic flux to pole. Air-gap flux density can be achieved highly by utilized to set up the starting winding after the rest of the limited space in the poly magnet structure. By finite electromagnetic field analysis software Ansoft, Three-dimensional magnetic field can be analyzed in Poly-Magnet Line-start Permanent Magnet Synchronous Motor. The result show that poly magnet structure improves the air gap magnetic field strength; Under the premise of better starting capability, it can improve the power index of motor.

Currently, the application of permanent magnet synchronous motor is in a wide range of electric vehicle. Field oriented control algorithm is the main way to control permanent magnet synchronous motor, the magnetic field oriented control must be precise to get the rotational position of the motor. Therefore, the performance of the motor position sensor directly affects the accuracy of the magnetic field oriented control. There are three main kinds of sensors: photoelectric position sensor, magnetic position sensor and magnetic sensor. Due to its superior performance, the application of magnetic position sensors is increasingly widespread. This paper designed permanent magnet synchronous motor position detection circuit for the position of permanent magnet synchronous motor based on TLE5012 used to detect the position and 32-bit micro-controllers Infineon TC1767 used as the main chip.

Periodic Inputs

A permanent magnet synchronous motor (PMSM) model with smooth air gap and an exogenous periodic input is introduced and analyzed in this paper. With a simple mathematical transformation, a new nonautonomous Lorenz-like system is derived from this PMSM model, and this new three-dimensional system can display the complicated dynamics such as the chaotic attractor and the multiperiodic orbits by adjusting the frequency and amplitude of the exogenous periodic inputs. Moreover, this new system shows a double-deck chaotic attractor that is completely different from the four-wing chaotic attractors on topological structures, although the phase portrait shapes of the new attractor and the four-wing chaotic attractors are similar. The exotic phenomenon has been well demonstrated and investigated by numerical simulations, bifurcation analysis, and electronic circuit implementation.
