Overview Design of 3-Phase Electric Motor 5.5kW 7.5Hp

The 3-phase electric motor features a robust and sturdy design, suitable for industrial applications requiring high performance. The outer casing of the electric motor is made of cast iron or solid die-cast aluminum, protecting internal components while providing good heat dissipation during operation. With high-quality copper-wound coils, the motor ensures optimal power transmission efficiency and minimizes electrical losses.

Internal Structure of 3-Phase Electric Motor

The 3-phase electric motor 5.5kW 7.5Hp is wound with 100% copper wire, featuring an external aluminum housing design that helps cool the motor and increase product durability.

• Motor Casing: The outer frame protects internal components from environmental impacts. This part is usually made of cast iron or die-cast aluminum, ensuring sturdiness while supporting heat dissipation when the motor operates continuously. Depending on the design, the capacitor can be placed in the terminal box or arranged in a separate position on the motor body.
• Stator (stationary part): A fixed assembly consisting of a magnetic steel core and a copper winding system. When current flows through the windings, the stator generates a rotating magnetic field, playing a crucial role in creating motion for the motor.
• Rotor (moving part): Placed inside the stator, it receives the impact of the magnetic field to create rotational motion. The rotor structure typically uses a squirrel-cage design, helping the motor operate stably, durably, and with minimal maintenance.
• Motor Shaft: Directly connected to the rotor, it functions to transmit torque outward to drive equipment such as gearboxes, pulleys, or industrial machinery.
• Bearings: Located at both ends of the shaft to support the rotation of the rotor, reduce friction between mechanical parts, help the motor run smoothly, reduce noise, and enhance durability.
