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 DC motors, AC motors do not have a commutator (see the commutation of DC motors), so AC motors are simple in structure, easy to manufacture, firmer, and easy to be made into high-speed, high-voltage, high-current, and large-capacity ones. Motor. The power coverage of AC motors is very large, from a few watts to hundreds of thousands of kilowatts, or even millions of kilowatts. In the early 1980s, the largest steam turbine AC motor reached 1.5 million kilowatts. So what are the types of AC motors? Let's take a look next.

AC motor spindle introduction

AC motor is a very broad classification. The type of AC motor itself is very large. AC motor itself can also be divided into low speed and high speed. Low speed can be called low-speed AC motor and AC low-speed motor. High speed can be called high-speed AC motor and high-speed AC. Electric motors, AC high-speed motors, and high-speed AC motors can be called electric spindles, high-speed electric spindles, and so on.

Classification of AC motors by function

AC motors are usually divided into AC generators, AC motors, and synchronous cameras according to their functions. Due to the reversibility of the motor's working state, the same motor can be used as both an alternator and a motor.

It is not very precise to divide AC motors into AC generators and AC motors, but some AC motors are mainly used as generators, and some Jiaoliu motors are mainly used as electric motors.

AC motors by type

AC motors are divided into two categories: synchronous AC motors and asynchronous AC motors. The speed ns of the rotor of the synchronous AC motor is the same as the speed of the rotating magnetic field, which is called the synchronous speed. There is a strict relationship between ns and the frequency (f) of the connected alternating current and the number of pole pairs (P) of the motor.

In China, the power frequency is 50 Hz, so the synchronous speed of a pair of pole motors in a three-phase AC motor is 3000 rpm, and the synchronous speed of a two pair of pole motors in a three-phase AC motor is 1500 rpm, and so on. The speed of the rotor of an asynchronous AC motor is always lower or higher than the speed of its rotating magnetic field, hence the name of asynchronous. The difference between the rotor speed of the asynchronous AC motor and the rotating magnetic field speed (called slip) is usually within 10%.

Guangzhou Yuexun Electric Appliance Co., Ltd. has already calibrated the connection test of AC motors before leaving the factory and is committed to producing more types of AC motors. If you are in the military AC motor business, you can consider using our cost-effective products. You are also welcome to cooperate with us to produce more types of AC motors.
