3-Phase Electric Motor 18.5kW 25Hp

The 3-Phase Electric Motor 18.5kW 25Hp belongs to the high-power 3-phase electric motor segment above 3.7kW, specifically designed for industrial machinery systems requiring continuous operation and heavy-duty capacity. With the ability to generate high torque, powerful, durable, and stable operation, the product effectively meets the needs of manufacturing plants, processing lines, industrial water pumping stations, etc., helping to optimize productivity and save operating costs.

General Design of the 3-Phase Electric Motor 18.5kW 25Hp

The 3-phase electric motor is solidly designed, meeting high-efficiency standards, suitable for continuous operation and heavy-duty systems. The outer casing of the electric motor is usually made of cast iron or solid aluminum for effective heat dissipation and good corrosion resistance. The machine body is coated with a characteristic dark blue powder coating, increasing oxidation resistance. The motor shaft is sturdy, made of steel or stainless steel, making it easy to connect with drive equipment. At the rear of the motor, a cooling fan is equipped to help the motor operate stably and durably over a long period.

Internal Structure of the 3-Phase Electric Motor 18.5kW 25Hp

The internal structure of the 3-Phase Electric Motor 18.5kW 25Hp consists of the following main components:

• Stator: The outer part of the motor (also known as the motor housing), composed of windings that create alternating current, playing the role of supplying energy to the motor during operation.
• Rotor: The inner part of the motor, made of many thin metal sheets assembled together to form a cylinder, rotating within the magnetic field.
• Motor Shaft: Made of high-strength steel, it is where power and torque are transmitted to external equipment (such as pumps, fans, Gearbox).
• Bearings: Help the shaft rotate smoothly and minimize friction during operation.
• Terminal Box: The place to connect the 3-phase power supply to the motor.
• Cooling Fan and Fan Cover: Located at the rear of the motor, the fan rotates synchronously with the rotor to blow air to cool the motor body, maintaining a stable temperature during continuous operation.
