3-Phase Electric Motor 2.2kW 3Hp

The 3-Phase Electric Motor 2.2kW 3Hp is an industrial device designed to meet the demands of powerful and continuous operation in modern machinery systems. With a power rating of 2.2kW (equivalent to a 3-Phase Motor 3Hp configuration), this versatile 3-phase electric motor falls under the 3.7kW threshold, making it ideal for various applications such as conveyor drives, woodworking machinery, pumps, air compressors, and more. Manufactured according to German technological standards, this electric motor stands out for its high durability, energy efficiency, and easy integration with other equipment in the production line.

General Design of the 3-Phase Electric Motor 2.2kW 3Hp

The electric motor features an eye-catching design with a characteristic blue color, and its housing is constructed from cast iron or aluminum. Externally, the motor is protected by a fan cover to ensure user safety. At the rear, a cooling fan cools the entire motor body. The motor shaft is made of pure stainless steel, helping to prevent and avoid rust in corrosive environments.

Internal Structure of the 3-Phase Electric Motor 2.2kW 3Hp

The internal structure of the 3-phase electric motor 2.2kW 3Hp consists of the following main components:

• Stator: This is the stationary part of the motor, comprising electrical engineering steel cores and copper winding coils. When energized, the stator generates a rotating magnetic field, which is the primary factor enabling the motor to produce mechanical movement.
• Rotor: The rotor is located inside the stator and rotates around the axis when subjected to the magnetic field. The squirrel-cage rotor design is widely used due to its stable operation, high durability, and low maintenance costs.
• Motor shaft: This is the mechanical component attached to the rotor, responsible for transmitting power and torque from the motor to external devices such as gearboxes, conveyors, pulleys, or other transmission mechanisms.
• Bearings: Installed at both ends of the shaft to support and position the rotor during rotation. This component helps reduce friction, minimize vibration, lower noise, and contribute to extending the motor’s lifespan.

How Many Poles Does the 3-Phase Electric Motor 2.2kW 3Hp Have?

Instructions for Wiring the 3-Phase Electric Motor 2.2kW 3Hp

Step 1: Open the terminal box compartment of the motor

• Use a wrench or screwdriver to remove the retaining bolts of the protective cover on top of the 3Hp motor terminal box.
• Once the cover is lifted, you will access the insulating terminal board containing 6 copper terminals corresponding to the inner coil ends inside the stator, pre-numbered in order.

Step 2: Identify the actual power supply terminal diagram

• At the terminal board position, the connection terminals are arranged in 2 parallel fixed rows.
• To supply power, technicians only operate on the primary load terminal row (usually located in the bottom row, visually labeled as U1 – V1 – W1).

Step 3: Position and secure the phase power cables to the contact terminals

• Route the 3 live phases (L1, L2, L3) of the 380V 3-phase power grid through the rubber wire-routing gasket into the terminal box.
• Securely position each phase wire end to the 3 terminals U1, V1, W1 using nuts.

IMPORTANT SAFETY NOTICE:

• The tightening torque of the nuts at connection points must be adequate-do not leave them loose as this will cause heat generation, motor stalling, and the risk of phase loss burning the copper windings.
• Strictly keep the position unchanged, do not reverse power wires over the upper common terminal row (U2, V2, W2) when not changing the Star or Delta operation scheme.

Step 4: Complete insulation and check the motor shaft rotation direction

• Reinstall the waterproof gasket, close the terminal box lid, and tighten the positioning screws to completely isolate dust from the production environment.
• Turn on the circuit breaker to test no-load operation for the 2.2kW motor. If the cooling fan at the rear of the motor rotates counterclockwise (or opposite to the direction arrow indicated on the motor body), turn off the main switch, swap the positions of 2 power supply wires to reverse the rotation direction of the motor shaft.
