This article presents an application of cryogenic impact deformation in effective grain refinement in coarse-grained copper. Ultrafine-grained microstructure was processed by means of cryogenic impact deformation using an air hammer with an initial impact velocity of 7.35ms−1. For strain ε=2.21, TEM observation showed that the initial equiaxed coarse grains (18μm) evolved into a lamellar structure...
The motor of a mini electric vehicle uses dozens of storage batteries as power supply, which has low voltage and large current. Therefore, the loss and temperature raise of the motor is high. In this paper, the loss of different induction motors for mini electric vehicles is calculated and the effects of rotor materials and air gap length on the performance of these motors are studied. The analyses...
A novel method for seawater desalination based on the rotation coupling electromagnetic theory is proposed and the concept of electric mesh grid is given. The desalination function of electric mesh grid is realized by the electric field which is produced by network of high-density with the charge of the contrary sign. The process principle of electric mesh grid is introduced. The field distribution...
To improve the torque performance of wheel motor, a concentrated winding motor with 12-slot-10-pole, embedded magnets rotor structure is presented in this paper. The influence of motorpsilas parameters such as the PMpsilas magnetization orientation length, the winding turns and inner diameter of stator on output torque is discussed by using finite element method. The design method of increasing motor...
