Design of the 3-phase electric motor 0.25kW 0.34Hp

The electric motor features a blue aluminum housing, lightweight and easy to install. The rear is equipped with a cooling fan, helping to dissipate heat effectively and protected by a dust-resistant fan cover. The motor shaft is made of stainless steel, heat-treated at high temperatures to ensure durability and prevent rust and corrosion during use.

Internal structure of the motor

To understand the operating principle and performance of the 3-phase electric motor, it is first necessary to grasp the structure of the main internal components.

• Stator: The outermost part, consisting of windings that generate alternating current, providing energy for the motor to operate. The stator is stationary and typically has a characteristic dark blue color.
• Rotor: The internal part of the motor, constructed from multiple metal plates combined into a cylinder. The rotor rotates within the magnetic field to create motion.
• Motor shaft: The core transmission component, connected to the rotor to convert torque into mechanical energy, driving external machinery.
• Bearings: Installed at both ends of the shaft to minimize friction, ensure the rotor rotates smoothly and quietly, and keep the shaft accurately centered.
• Cooling fan: Attached to the rear of the motor shaft, it rotates automatically when the motor runs to blow air for heat dissipation, keeping the machine’s temperature at a safe level.

Classification of the 3-phase electric motor 0.25kW 0.34Hp
