3-Phase Electric Motor 11kW 15Hp

The 3-Phase Electric Motor 11kW 15Hp is a high-power 3-phase electric motor over 3.7kW, specifically designed for high-load industrial production systems. With powerful, stable operation and long service life, this product is suitable for installation in automated production lines, crushers, industrial presses, or high-capacity pump systems. This is the optimal choice for units requiring motors to run continuously with high efficiency and superior durability.

Overview design of the 3-Phase Electric Motor 11kW 15Hp

The 3-phase electric motor is sturdily designed, suitable for harsh industrial environments. The outer casing of the electric motor is made of solid cast iron or aluminum and coated with electrostatic paint, helping to resist corrosion and dissipate heat effectively. The structure of foot mount (B3 type), flange mount (B5 type), or a combination of both (B35 type) provides installation flexibility. The motor shaft is made of stainless steel, offering good load-bearing capacity. The entire internal winding is wound with 100% copper wire, ensuring high transmission efficiency and long-term stable operation.

Internal structure of the 3-Phase Electric Motor 11kW 15Hp

To handle heavy workloads and operate stably at 15 horsepower, every internal component of the machine must meet rigorous precision and material quality standards:

• Stator: The fixed magnetic core is tightly pressed from magnetically oriented electrical steel sheets. Inside the slots is an electromagnetic winding system made of 100% pure copper wire, impregnated and baked with a high-grade insulating varnish (Class F) to prevent electrical discharge at high temperatures.
• Rotor: The squirrel-cage rotating core is made of cast alloy steel integrated with guide bars. The rotor is CNC-lathed and dynamically balanced using digital technology to completely eliminate vibration and centrifugal eccentricity during high-speed rotation.
• Bearings: Installed at both ends of the shaft (front and rear flanges), using high-friction industrial bearing lines integrated with specialized lubricating grease to help the shaft rotate smoothly and quietly.
• Cooling system: Uses a centrifugal fan made of synthetic plastic or lightweight aluminum, coaxially mounted at the rear of the machine to continuously draw air circulating along the cast iron housing ribs.

Which gearbox does the 3-Phase Electric Motor 11kW 15Hp combine with?

With the characteristic 11kW power and large standard shaft sizes (42mm, 48mm), pairing with a gearbox requires prioritizing heavy-load lines to optimize pulling power without damaging the gears.

• Heavy-duty helical gearbox (R, S, K, F series): This is the safest mechanical drive option. It is recommended to use gearbox sizes such as R77, R87 or K77, K87 for high-intensity conveyor and bucket elevator systems.
• Cast iron worm gearbox: Suitable for combining with WPA, WPS, WPX codes size 135 or size 155, commonly used for winches or traditional mechanical machinery.
• Aluminum housing gearbox (NMRV worm gearbox): Can be flexibly connected with NMRV size 110 or size 130 for assembly spaces that require compactness, aesthetics, and rust resistance.
• Other drive options: Using a V-belt connected via multi-groove B-section or C-section pulley, heavy-duty chain sprockets, or flanged shaft coupling (flexible coupling).

Instructions for wiring the 3-phase electric motor

Before proceeding, you should refer to electric motor videos to clearly understand the structure and location of the terminal posts, ensuring accurate operations and minimizing errors.

Step 1: Remove the terminal box cover of the electric motor

Use a suitable screwdriver to remove the 4 fixing bolts on the terminal box cover. After opening the cover, you will see the terminal wiring ends inside. For common 3-phase motors, this area typically has 6 clearly labeled wire ends.

Step 2: Identify the terminal posts and 380V power supply

The wire ends in the terminal box are arranged in two rows. The bottom row, labeled U1, V1, W1, is where the input power supply is connected.

Step 3: Connect the 3-phase power supply to U1, V1, W1

Prepare 3 phase wires from the 380V power supply and connect them sequentially to the U1, V1, W1 terminal posts. It is necessary to ensure correct positioning for the motor to operate stably.

Important safety note:

Crimp terminals must be tightened to ensure good electrical contact, preventing electrical sparks that cause short circuits and fires. Do not connect the power source to the top terminal row (U2, V2, W2) as this may damage the motor windings.

Step 4: Close the cover and test run

After completing the wiring, close the terminal box cover tightly and tighten the bolts to protect the device from dust and moisture. Power on to check operation. If the motor rotates in the reverse direction of your preference, simply disconnect the power and swap the positions of any two of the three phase wires to reverse the rotation direction.

Proper execution not only helps the system operate stably but also ensures long-term safety. Electric motor videos from Thanh Thai Motor will be a useful reference for users during actual use.
