Due to ventilation structure of high power high-speed permanent magnet motor is complex and rotor cooling is difficult, the rotor cooling system was designed for a 1020kw 19000r/min high-speed permanent magnet motor and fluid field calculation model was established through the fluid flow CFD simulation software, and then the solving regional and boundary conditions of the 3D fluid field was determined. The numerical calculation and analysis was carried out and 3D fluid field distribution was get within the ventilation system. On the basis of the results of the flow field calculation, the coefficient of wall heat can be got more accurately, which provides a basis for the optimization and count of the MW-level high-speed motor temperature field.

Flux Weakening

Soft ferrite has the characteristics of high permeability, high resistivity, low loss. Based on this, a new flux-weakening structure of high-speed permanent magnet motor was presented. The structure relies on changing the saturation of soft magnetic ferrite to change the equivalent magnetic resistance of permanent magnet magnetic circuit in the motor, so the main flux of the permanent magnet motor can be reduced. By the 3D Finite Element analyses, the magnetic field distribution characters in the air gap can be pointed out. The analysis results prove the flux-weakening method is presented in this paper is correct and feasible. It can provide a practical flux-weakening method of the high-speed PM motor.
