“…The magnetic density is decomposed into radial and tangential magnetic density, as shown in Figure 11. Assuming that both change according to the sinusoidal law, and the peak values of both are calculated in Equation (2). Table 10 shows the core loss of each region obtained by substituting the radial and tangential components of the magnetic density of each measurement point into Equation (2).…”

“…Method 3 uses the Fourier decomposition. The radial and tangential components of the magnetic density are decomposed by the Fourier transform, and then the peak value of each harmonic magnetic density is substituted into Equation (2). Table 11 shows the Fourier decomposition of the radial and tangential components of the magnetic density at each monitoring point.…”

“…Accurate calculation of losses is critical to the safe operation of the motor [1]. Different losses occur during the operation of motors, including core losses of stator and rotor, copper losses of armature winding, eddy current losses of permanent magnet, and mechanical losses [2]. Because the core loss is closely related to the magnetic flux density and frequency of the motor, and the magnetic flux density distribution of the motor is complicated, it is difficult to calculate the core loss accurately in the study of various loss calculations.…”

To reduce the loss of a drive motor and improve the output efficiency of the drive motor, this paper explores the influencing factors of core loss of an embedded combined magnetic pole drive motor (ECMPDM) for new energy vehicles. The mathematical model of the core loss of the drive motor is established. The monitoring points are selected in different areas of the stator to analyze the distribution of magnetic density, and the correctness of the model is preliminarily verified. Taking the motor core loss as the primary objective of optimization, the multi-objective optimization of the stator slot structure size is carried out by the response surface analysis method. The average value of the stator core loss and the radial magnetic density amplitude of the B point is taken as the two optimization objectives, and the optimal solution of the model is selected by the Pareto frontier distribution diagram. The optimal stator structure is analyzed, and the core loss value is calculated by three methods and compared with the simulation value. The prototype experiments of the optimized motor are carried out, and the no-load core loss experiment, rated voltage characteristic experiment, and peak power characteristic experiment are carried out, which verify the rationality of the optimized size and structure of the embedded combined magnetic pole drive motor for new energy vehicles and provide a possibility for the analysis of the temperature field of the embedded combined magnetic pole drive motor for new energy vehicles.

“…Stator and rotor core of a traditional motor is mostly made of silicon steel material, but its inherent characteristics can bring big loss, heat, and other problems. As a new type of soft magnetic material, amorphous alloy material [11][12][13][14][15][16][17] has excellent electromagnetic properties, like high permeability, low coercivity, and low loss [30,31]. Applying amorphous alloy material to the motor core instead of the conventional silicon steel sheet material can significantly reduce the iron consumption of the motor, improve the efficiency of the motor, and achieve remarkable energy saving effect.…”

A bearingless induction motor (BL-IM) is a new type of motor integrating suspension and rotation functions. Higher requirements are put forward for its suspension performance. Due to the material advantages of a new type of amorphous alloy with high magnetic conductivity, low loss, and low coercivity, it is considered to be used in the BL-IM rotor to reduce iron loss and improve the electromagnetic performance of the BL-IM. Finite element analysis software is used to analyze the performance of two different kinds of motors with the rotors made of conventional silicon steel and amorphous alloy, respectively. The magnetic field density distribution, torque, speed, and radial force are compared between the two motors. The results show that the speed of amorphous alloy motor increases faster, and the rotor has better suspension characteristics. Moreover, the amorphous alloy material has a smaller density; the material properties can effectively reduce the weight of the motor; it is beneficial to the operation of the BL-IM in special environments.
