Overview: 3-Phase Asynchronous AC Motors

A 3-phase asynchronous AC motor—Often called a 3-phase induction motor—is a highly reliable and efficient electric motor that uses 3-phase alternating current to generate mechanical power. They are the workhorses of industry and agriculture, widely used to run equipment like water pumps, conveyors, fans, and elevators.

Long life and robust construction: Cage rotor design and IP55, IP56, IP65 and IP66 protection make the motor durable even in harsh environments.

Low maintenance requirement: Simple mechanical construction, low friction and loss minimize maintenance costs.

High starting torque: Capable of rotating heavy loads without difficulty with the first movement.

Wide product range

Offers special solutions suitable for different industrial processes in terms of power, speed, number of poles and frame sizes.

Full compatibility with three-phase grids

Easy commissioning and system integration as it is compatible with the standard supply structure.

Low vibration and noise level

The balanced electromagnetic design reduces vibration levels, positively affecting equipment life.

Common types

Squirrel Cage Motor

The squirrel cage motor is the most common type of three-phase induction motor, named after its rotor structure, which resembles a "squirrel cage." The rotor is made of copper or aluminum bars, which are connected by short-circuit rings. This type of motor is simple in structure, durable, and easy to maintain, making it ideal for applications requiring constant speed.

Slip Ring Motor

The slip ring motor has a rotor made of windings, which are connected to an external power source via slip rings and brushes, allowing for speed and torque adjustments. Compared to the squirrel cage motor, the slip ring motor can handle higher starting torque and offers more flexible control through external current adjustments.

Variable Frequency Drive (VFD) Motor

The variable frequency drive (VFD) motor combines a variable frequency drive with a three-phase induction motor. The variable frequency drive adjusts the frequency of the input current to the motor, thus controlling the motor's speed, improving energy efficiency, and providing greater flexibility.

Application

Automotive: Electric motors are used in electric vehicles (EVs) for propulsion. They convert electrical energy into mechanical motion to move the vehicle forward.

Manufacturing: Electric motors are used in various industrial applications such as machine tools, industrial robots, conveyors, compressors, pumps and fans.

Home Appliances: Electric motors are found in many home appliances such as refrigerators, washing machines, dryers, vacuum cleaners, blenders, fans and air conditioners.

Consumer Electronics: Electric motors are used in consumer electronics devices such as smartphones (vibrators), drones, remote control toys, cameras and printers.

Medical: Electric motors are used in medical equipment such as imaging scanners, infusion pumps, respiratory support devices and electric wheelchairs.

Marine: Electric motors are used in boats and ships for propulsion, dynamic positioning and operation of onboard equipment.

Aeronautics

Electric motors are used in aircraft and drones for propeller drives, flight control actuators and auxiliary systems.

Renewable Energy

Electric motors are used in wind turbines to convert wind energy into electrical energy. They are also used in solar panel systems to track the sun.

Rail

Electric motors are used in trains and streetcars for propulsion. Electric locomotives use electric motors to drive the axles.

Agricultural sector

Electric motors are used in agricultural equipment such as electric tractors, irrigation systems, harvesting machines and ventilation systems.

FAQ

Q: How does an asynchronous AC motor work?

A: They operate on the principle of electromagnetic induction, where the rotor (rotating part) turns at a slightly slower speed than the synchronous speed of the magnetic field created by the stator (stationary part).

Q: What are the three types of 3-phase motors?

A: The three primary types of three-phase motors are Squirrel-Cage Induction, Wound-Rotor Induction, and Synchronous. They are distinguished by their rotor construction and how they interact with the stator's magnetic field.

Q: How do you maintain an asynchronous motor?

A: Cleaning work: Regularly clean dust, oil and other debris on the motor housing and cooling fan to keep the motor clean for heat dissipation. Be careful to avoid wiping with a wet cloth to prevent electric shock. Tightening inspection: Check whether the motor mounting bolts, anchor bolts, etc.

Q: Do you offer OEM Service?

A: Yes. We offer OEM service.

Q: What is your warranty?

A: Our warranty is One Year. Any parts damaged within warranty. We will provide new one for free and supply the solution within 3 workdays. However, motor damage caused by improper operations such as phase - loss, over - loading, etc. is not covered by the warranty.
