TEC IE3 3 Phase Motor – 4kW, 4 Pole

The TEC IE3 premium efficiency 3 phase motor is designed for reliable, energy-efficient operation across a wide range of industrial and commercial applications.

With a power rating of 4kW, 4 pole configuration, and 112M IEC frame size, this motor provides consistent performance, reduced energy consumption, and long service life in both light and heavy-duty environments.

This range of motors is available in an aluminium frame (0.75-7.5kW) 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 (7.5-315kW) for more heavy-duty durability.

Key Features

• 4kW output power
• 4 pole configuration
• IE3 premium efficiency motor
• 400V three-phase motor (typical)
• Aluminium frame
• B3 foot mount as standard
• Optional B34 (foot & face) and B35 (foot & flange) mounting configurations
• Designed for continuous duty operation
• Reduced energy consumption and operating costs

Applications

These motors are suitable for a wide range of industrial applications, including:

• Pumps
• Fans and ventilation systems
• Compressors
• Conveyors
• Industrial machinery
• Processing equipment

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 and face mounting
• Ideal for flexible installation setups

B35 – Foot & Flange Mount

• Foot and flange mounting
• Suitable for more rigid or heavy-duty installations

Pole Configuration Explained

The number of poles determines motor speed:

• 2 Pole Motors
  Approx. 3000 RPM
  Ideal for high-speed applications such as fans and blowers
• 4 Pole Motors
  Approx. 1500 RPM
  Most common, suitable for general-purpose applications
• 6 Pole Motors
  Approx. 1000 RPM
  Lower speed with higher torque, suitable for heavier loads
• 8 Pole Motors
  Low speed (Approximately 750 RPM)
  Higher torque output
  Ideal for controlled speed and heavy-duty applications
