3-Phase Inverter Duty Motor 90kW 125Hp

The 3-Phase Inverter Duty Motor 90kW 125Hp is a high-power electric motor equipped with advanced inverter technology, allowing precise voltage and frequency control. As a result, rotational speed and torque are always balanced to suit operating needs, helping to save significant electricity while maintaining stability and durability for the entire system.

Overall design of the 3-Phase Inverter Duty Motor 90kW 125Hp

The inverter duty motor is a 3-Phase Electric Motor made from a single-piece cast iron housing, resistant to deformation. The entire surface is coated with a thick electrostatic paint layer, enhancing corrosion resistance and protecting the motor from moisture, dust, and chemical vapors in harsh environments.

A notable advantage is the separate forced cooling fan located at the rear of the motor. This fan creates a strong, stable, and continuous airflow, helping the motor cool down even when running at low speed or working for a long time under heavy loads.

Detailed structure of the 3-phase inverter duty motor

The inverter duty motor is modernly designed, ensuring high performance and durable operation with main components:

• Stator: Uses pure copper wire, ensuring optimal electrical conductivity and reduced energy loss.
• Rotor: Consists of tightly assembled electrical steel sheets, enhancing transmission efficiency and mechanical durability.
• Terminal box: Arranged into two separate compartments, convenient for connecting the main power supply and the forced cooling fan, while increasing safety levels.
• Forced cooling fan: Operates independently, maintaining efficient heat dissipation and protecting the motor in demanding environments.
• Inverter circuit: Allows flexible frequency changes, smooth startup, and limits inrush current.
