3-Phase Inverter Duty Motor 7.5kW 10Hp

The 3-Phase Inverter Duty Motor 7.5kW 10Hp is a modern electric motor combined with an inverter, capable of changing frequency and input current to control rotational speed according to practical needs. Thanks to its fast load adaptability, this inverter duty motor is becoming the preferred choice in many industries, especially systems requiring high precision, stability, and high performance.

Design Overview of the 3-Phase Inverter Duty Motor 7.5kW 10Hp

The inverter duty motor is manufactured on advanced technical lines, using a thick and sturdy cast iron housing. The anti-rust powder coating helps the motor withstand dusty, humid environments and mechanical impacts well.

The highlight of this motor series is the independent forced cooling fan located at the rear. As a result, the motor is always continuously cooled even when running at low speeds or operating for long periods under heavy loads.

Detailed Structure of the 3-Phase Inverter Duty Motor

The 3-Phase Inverter Duty Motor 7.5kW 10Hp belongs to the 3-phase electric motor series with the following main structures:

• Stator: Pure copper windings help conduct electricity well, maintain a stable magnetic field, and limit heat generation.
• Rotor: Made of cold-stamped and tightly pressed electrical steel sheets (silicon steel). The rotor shaft undergoes dynamic balancing via digital CNC technology to eliminate centrifugal force, ensuring ultra-smooth operation without vibration even at high-frequency ranges.
• Terminal box: Consists of two parts, the front for connecting the main power source and the rear for supplying power to the forced cooling fan.
• Forced cooling fan: Operates independently, providing a strong airflow to help dissipate heat evenly and extend motor life.
• Inverter circuit: Converts alternating current into a variable-frequency power source, precisely controlling speed and torque.

Classification of the 3-Phase Inverter Duty Motor 7.5kW 10Hp

The 3-Phase Inverter Duty Motor 7.5kW 10Hp has different classification types. Choosing the correct number of poles will help optimize performance and increase the lifespan of the entire system.

Technical Standard Wiring Guide for 3-Phase Electric Motors

Wiring an inverter duty motor requires technicians to be extremely careful in separating the two distinct power source assemblies. Below is a detailed guide on how to set up the power supply for industrial inverter motors, helping technicians and users operate safely, quickly, and accurately.

Stage 1: Handling the motor terminal box

• Prepare a screwdriver of a suitable size.
• Unscrew the 4 bolts/screws fixing the four corners of the connection assembly protective box cover.
• Open the box cover to access the internal electrical connection terminal studs.

Stage 2: Installing the 380V power transmission line

• Separate the 3 power cables carrying the 380V current.
• Directly connect these 3 cables to the 3 terminal stud locations marked with symbols: U1, V1, and W1, respectively.
• Use pliers or specialized tools to tighten the connections securely, preventing looseness that causes short circuits during machine vibration.

Stage 3: Powering up and inspection

• After closing the protective box cover safely, turn on the circuit breaker (CB) to supply 380V power.
• Evaluate the operating quality by observing the movement of the shaft to see if the motor starts smoothly and in the correct direction.

The 3-Phase Inverter Duty Motor 7.5kW 10Hp with a pure copper winding core combined with the Class F insulation standard helps the device completely resist the risks of overheating or magnetic field breakdown.
