Motor Overview

This version is supplied in Foot Mount format so it can be installed on base-mounted machine beds and fabricated steel structures. This 4 pole configuration is widely used where balanced all-round speed and torque are needed.

---

Why This Version?

This 0.25kW 4 pole Tec motor is intended for customers who need an IEC 71B3 motor rather than a generic substitute. The published frame, mounting, and shaft/flange detail (14mm Shaft) make it easier to match to replacement and OEM requirements.

Frequently Asked Questions

What kind of machinery is a 0.25kW 4 pole motor good for?

This depends on the machine duty, mounting style, speed requirement, and mechanical fit, but this product is typically chosen for installations where a 0.25kW 4 pole IEC 71B3 motor is required.

What does the IEC 71B3 mounting arrangement mean?

The IEC mounting code identifies the frame and mounting arrangement of the motor, helping you match it to the correct gearbox, pump, machine flange, or base mounting setup.

Will this motor work on an inverter drive?

Many industrial AC motors can operate with inverter drives, but final suitability depends on the application, duty cycle, and control requirements.

How protected is an IP55 motor in normal industrial use?

IP55 means the motor is protected against dust ingress and low-pressure water jets, making it suitable for most indoor industrial environments.
