An AC motor is a machine that converts the electrical energy of alternating current into mechanical energy. AC motors are mainly composed of electromagnet windings or distributed stator windings that generate a magnetic field and a rotating armature or rotor. Electric motors are made using the phenomenon of energized coils being forced to rotate in a magnetic field. The AC motor consists of a stator and a rotor. The stator and the rotor use the same power supply, so the direction changes of the current in the stator and the rotor are always synchronized. AC motors work on this principle. Three-phase asynchronous motors are widely used in industrial production due to their good performance and high cost performance.
Here is the list
Advantages of AC Motors
Common parameters of AC motor
Protection level 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 coverage of AC motor power is very large. AC motors are generally divided into several categories according to their function: alternators, AC motors, and synchronous modulators. Due to the reversible Henglin Seiko AC spindle in the working state of the motor, the same motor can be used as both a generator and a motor.
Rated speed: refers to the speed of the motor at rated power. That is, the full load speed of the motor, so it is also called the full load speed. It is represented by the symbol "n" and the unit is "rev/min". The synchronous speed of the motor = 60*frequency/number of pole pairs, 6 poles: 60*50/3=1000 rpm, and the asynchronous speed is slightly reduced by about 980 rpm.
Protection level: IP (INGRESSPROTECTION) protection level system is drafted by IEC, which classifies electrical appliances according to the characteristics of dustproof, prevention of foreign objects (including tools, human fingers, etc.) intrusion, moisture resistance, and waterproof intrusion. The IP degree of protection consists of two numbers. The first number represents the rating of the appliance against the intrusion of dust and foreign objects. The second number represents how airtight the appliance is against moisture and water intrusion. The higher the number, the higher the protection level. higher.
