TEC IE3 Premium Efficiency 3 Phase Electric Motor, 11kW, 8 Pole, 180L IEC Frame (Cast Iron).

TEC 3 Phase Motor – 7.5kW, 8 Pole, IE3

The TEC 3 phase 8 pole motor is a high-quality electric motor designed for low speed, high torque applications in industrial and commercial environments.

With a power rating of 7.5kW, 8 pole configuration, and 160L IEC frame size, this motor operates at 710 RPM, making it ideal for applications requiring controlled speed and increased torque.

TEC 8 pole motors are available in an aluminium frame (0.12-0.55kW) offering excellent heat dissipation and corrosion resistance, making it ideal for applications where weight, efficiency, and reliability are important. This range is also available in a cast iron frame (0.75-132kW) for more heavy-duty durability.

Key Features

• 7.5kW output power
• 8 pole motor (710 RPM)
• IE3 Premium efficiency class
• 400V three-phase motor (typical – adjust if needed)
• Cast iron frame
• B3 foot mount as standard
• Optional B34 (foot & face) and B35 (foot & flange) mounting configurations
• Suitable for continuous duty operation
• Designed for high torque, low speed applications

Applications

8 pole motors are ideal for applications requiring lower speeds and higher torque, including:

• Conveyors
• Gear-driven systems
• Mixers and agitators
• Pumps requiring controlled flow
• Heavy-duty industrial machinery

IEC Frame Sizes Explained

Motor frame sizes are standardised under International Electrotechnical Commission (IEC) guidelines, ensuring compatibility across manufacturers.

The frame size defines key mounting dimensions such as:

• Shaft height
• Mounting hole positions
• Shaft diameter

This allows motors with the same IEC frame size to be interchanged without mechanical modification.

Motor Mounting Configurations

B3 – Foot Mount (Standard)

• Base-mounted motor
• Most common configuration

B34 – Foot & Face Mount

• Foot + front face mounting
• Increased installation flexibility

B35 – Foot & Flange Mount

• Foot + larger flange
• Suitable for rigid/heavy-duty mounting

Motor Efficiency Classes Explained

Electric motors are classified under International Electrotechnical Commission efficiency standards:

• IE2 – High Efficiency
  Improved energy performance for general industrial use
• IE3 – Premium Efficiency
  Lower energy consumption and ideal for continuous operation
• IE4 – Super Premium Efficiency
  Maximum efficiency for energy-critical applications

Pole Configuration Explained

The number of poles in an electric motor determines its operating speed.

Typical speeds at 50Hz supply:

• 2 Pole Motors
  High speed (Approx 3000 RPM)
  Ideal for fans, blowers, and applications requiring high rotational speed
• 4 Pole Motors
  Medium speed (Approx 1500 RPM)
  Most common and widely used for general-purpose applications
• 6 Pole Motors
  Lower speed (Approx 1000 RPM)
  Suitable for applications requiring higher torque at lower speeds
• 8 Pole Motors
  Low speed (Approximately 750 RPM)
  Higher torque output
  Ideal for controlled speed and heavy-duty applications

See Specification tab for speed of this motor.
