Tec 4kW 2 Pole Motor – 5.5HP 3000rpm IEC 112MB5 Flange Motor
This Tec 4kW 2 pole three-phase electric motor is built in IEC 112MB5 format with B5 mounting, making it suitable for fans, blowers, saws, polishing equipment, spindles, and other direct-drive machinery needing higher running speed. This version is aimed at users who need flange motor, dependable IE3 efficiency, and IP55 protection for day-to-day industrial service.
Motor Overview
This version uses a B5 mounting arrangement for large flange direct-coupled installation. In practice, that makes it a practical choice for pumps, gearboxes, mixers, and machines that bolt directly through a full flange. The 2 pole winding gives a nominal speed of 3000rpm, so it is normally selected where higher shaft speed and quicker response are important.
Why Choose This Configuration?
This exact model is best suited to buyers who specifically need an IEC 112MB5 motor in 4kW / 5.5HP. Compared with other mounting options in the same power and pole range, this version is intended for applications where a full-flange IEC motor is needed for direct registration onto the driven machine, while still keeping the same core electrical performance and aluminium IE3 construction.

Frequently Asked Questions
What applications suit this 4kW 2 pole motor?
This depends on the duty, load profile, mounting arrangement, and machine design, but this model is commonly selected for fans, blowers, saws, polishing equipment, spindles, and other direct-drive machinery needing higher running speed where an IEC 112MB5 motor format is required.
What does the IEC 112MB5 code mean?
It identifies the motor frame size and mounting arrangement, helping you match the motor correctly to the machine, gearbox, pump, flange, or base position already in use.
Will this motor work with an inverter drive?
Many industrial AC motors can be run from an inverter drive, but final suitability depends on application duty, speed range, cooling, and the control method being used.
How protected is an IP55 motor in normal industrial use?
IP55 means the motor is protected against harmful dust ingress and low-pressure water jets, which makes it suitable for most indoor industrial environments.
The options above help you move to the same motor in a different mounting style or jump to nearby power sizes while keeping the same pole configuration and mounting type.
