The Production Process of 3 Phase AC Induction Motor

The production of Yongzhuan 3 phase AC induction motor involves a highly systematic process to ensure efficiency, durability, and optimal performance. Below is our key steps in the manufacturing of 3-phase AC induction motors.


1. Design and Engineering

The production process begins with designing the motor to meet specific performance requirements. 

This involves:

Defining Specifications: Power rating, torque, efficiency, voltage, and speed.

Material Selection: Identifying suitable materials for the stator, rotor, and casing to ensure durability and efficiency.

Computer-Aided Design (CAD): Creating detailed 3D models and simulations to verify design performance.

2. Core Manufacturing

The stator and rotor cores are essential components, as they form the electromagnetic framework of the motor.

Stator Core Manufacturing:Thin sheets of electrical steel are punched or cut into precise shapes. The sheets are laminated and stacked to minimize energy losses due to eddy currents. These laminations are then pressed and assembled into the stator frame.

Rotor Core Manufacturing:Similarly, rotor laminations are created and stacked. For squirrel cage rotors, aluminum or copper bars are inserted into the rotor slots, and the ends are welded or die-cast to form a solid, conductive cage.

3. Winding the Stator

The stator windings are critical for creating the rotating magnetic field.

Copper or Aluminum Wire Coiling: High-precision machines are used to wind the wires into coils.

Insulation Application: Coils are insulated to prevent electrical faults.

Insertion into Stator Core: The windings are carefully placed into the slots of the stator core.

Interconnection: The coils are connected to form the three-phase winding system.


Winding the Stator of 3 phase motor


4. Assembly of Rotor and Stator

The rotor and stator are assembled into the motor housing. This step involves:

Precise Fitting: Ensuring minimal air gap between the rotor and stator to maximize efficiency.

Bearing Installation: Bearings are added to support smooth rotor rotation.

Shaft Alignment: The rotor shaft is aligned and fixed in place.

5. Motor Housing and Cooling System

The external housing and cooling components protect the motor and ensure heat dissipation.

Casing Manufacturing: Cast iron, steel, or aluminum casings are produced through casting or machining.

Cooling Fins or Fans: Attached to the housing to improve heat dissipation during operation.

Sealing: Ensures protection against dust, moisture, and external contaminants.

6. Testing and Quality Control

Rigorous testing is conducted at multiple stages to ensure the motor meets performance standards.

Electrical Testing: Checking insulation resistance, winding integrity, and overall electrical performance.

Mechanical Testing: Verifying rotor balance, shaft alignment, and bearing performance.

Thermal Testing: Monitoring heat generation and dissipation during operation.

Performance Testing: Evaluating efficiency, torque, speed, and noise levels under load conditions.


Testing and Quality Control of 3 phase ac induction motor


7. Surface Finishing

Once the motor passes all tests, it undergoes surface finishing to enhance durability and appearance.

Painting or Coating: Protects the motor from corrosion and environmental damage.

Labeling: Includes the motor's specifications, efficiency class (e.g., IE2, IE3, IE4), and compliance certifications.
