This article briefly introduces the characteristics of various aspects of the AC motor, and briefly introduces the structural design of the AC motor and the manufacturing cost of the AC motor.
Here is the list
Characteristics of AC Motors
AC Motor Structural Design
Stator structure determination of AC motor
1. The manufacturing cost of AC motors is relatively low.
2. With the development of vector frequency conversion technology, it has become possible to simulate DC with frequency conversion motor.
3. Compared with DC motors, it has the advantages of simple structure, convenient maintenance, low environmental protection requirements, energy saving and production increase, etc., so that AC speed regulation is widely used in industrial and agricultural production, transportation, national defense and daily life. .
An AC motor is a machine used to realize the mutual conversion of mechanical energy and AC electrical energy. Due to the tremendous development of AC power systems, AC motors have become the most commonly used motors. Compared with the DC motor, the AC motor has a simple structure, is easy to manufacture, and is relatively firm because there is no commutator. It is easy to make high-speed, high-voltage, high-current, high-capacity motors. The AC motor power supply covers a wide range. AC motors are generally divided into several categories according to their function: alternators, AC motors, and synchronous modulators. Due to the use of a reversible Henglin Seiko AC spindle\n in the working state of the motor, the same motor can be used as both a generator and a motor. It's not very accurate to divide motors into generators and motors, but some motors are mostly used as generators and some are mostly used as motors.
Gathering with friends, BB, who is very good at asking questions, asked a question, what are the steps of motor design? Ms. Sen thinks the question is particularly well-posed. Everything has an entry point for its work, and every work has its main thread and sequence. Of course, there are some ground rules for motor design. Today we will focus on the structural design principles and key points of AC motors.
After the overall structure is initially determined, the design usually starts with the stator. For the stator core, the fastening method in the axial and circumferential directions and the structure of the radial ventilation channel elements should generally be determined (if there is no radial ventilation channel, it will not be carried out); when the fan-shaped sheet is used, the fan-shaped sheet should also be determined. The way the material is divided, the number, size and arrangement of the dovetail grooves. In large motors, the specific structure of the stepped parts at both ends of the iron core should be determined. For the stator winding, the size of the end should be calculated first, and the fixing method should be determined.
