2022-9-6
The industrial application of high-speed motors with good quality and low price has attracted more and more attention. Compared with ordinary motors, professional high-speed motors are designed with smaller size, higher power density and faster response. These characteristics of high-speed motors are due to the unique structural design of atoms, the most important of which are the unique designs of high-speed motor rotors and stators.
1. Design features of high-speed motor rotors
The rotor of the high-speed motor will generate a strong centrifugal force at high speed. Under the large centrifugal force of the rotor, the rotor itself needs to have higher mechanical strength. At the same time, the greater friction force generated by high-speed rotation will lead to the friction loss and temperature rise of the rotor. This requires the rotor of the high-speed motor to have higher hardness and wear resistance and better high temperature resistance. High-speed motors have special requirements for material properties, and these special requirements mainly come from the above-mentioned more special use environment than ordinary motors. The material itself needs to have higher tensile and flexural strength. In addition, the material needs to be better structurally designed to achieve higher tensile strength. In addition, the high temperature resistance and hardness of the material are also required.
2. Design characteristics of high-speed motor stator
The stator in the high-speed motor is the most important heat dissipation medium. The heat generated during the high-speed rotation needs to be diffused through the stator. In the structural design, the stator of the stator high-speed motor adopts a ring winding structure. The winding in this structure is located in the yoke of the motor. Reduced rotor length and increased rotor stiffness. In addition, there are many outer grooves and inner grooves in this structure, and these inner and outer grooves can be used as heat dissipation channels to help the nails dissipate heat. Soft magnetic composite materials are receiving a certain degree of attention as a material for stators.
In summary, the material selection and structural design of the rotor and stator of high-speed motors have certain particularities compared with ordinary electrodes. At present, certain progress has been made in the material and structural design of rotors and stators of high-speed motors. The particularity of the structure also makes it possible to achieve high speed, high power density and more sensitive response of the high-speed motor. With the advancement of material science, the selection of related materials for high-speed motors will also be further improved, so as to solve some of the existing problems of high-speed motors and make the application of high-speed motors more widely
