3-Phase Inverter Duty Motor 110kW 150Hp

The 3-Phase Inverter Duty Motor 110kW 150Hp is an electric motor integrated with modern inverter technology to precisely control voltage and frequency. Therefore, the rotation speed and torque are always flexibly adjusted to suit each working mode. Below, Thanh Thai Motor will introduce this inverter duty motor in more detail!

Overall design of the 3-Phase Inverter Duty Motor 110kW 150Hp

The inverter duty motor is made of a monolithic cast iron housing, creating rigidity and minimizing deformation when working continuously in strong vibration environments. A thick electrostatic paint layer evenly covers the entire surface to resist oxidation, preventing the impact of moisture, dust, and corrosive chemicals.

The motor is also equipped with an independently operating forced cooling fan located at the rear of the body. This strong, stable, and continuous airflow ensures the motor is always cooled.

Detailed structure of the 3-phase inverter duty motor

The 3-Phase Inverter Duty Motor 110kW 150Hp is a 3-phase electric motor synchronously designed with the following main components:

• Stator: Completely wound with pure copper wire, reducing power loss and increasing winding durability.
• Rotor: Composed of tightly pressed electrical steel laminations, enhancing transmission efficiency and load-bearing capacity.
• Terminal box: Divided into 2 separate compartments for the main power supply and the forced cooling fan, making wiring easy and increasing safety.
• Forced cooling fan: Operates independently, maintains stable temperature, and protects the motor in harsh working environments.
• Inverter circuit: Capable of flexibly changing frequency, helping smooth operation.
