Motor Overview

The Tec 0.75kW 4 Pole Electric Motor in 80B5 flange mount format is intended for applications where concentric flange alignment matters more than base mounting. The 200mm spigot and IEC flange arrangement help the motor locate accurately onto compatible equipment, which is particularly useful for direct-coupled pump sets, geared drives, and compact machine assemblies.

Its aluminium construction keeps the motor practical to handle during installation while still offering the protection and rigidity needed for industrial service. This makes the 80B5 version especially valuable in OEM builds and service replacements where a flange motor is the required pattern.

Mounting & Installation Benefits

The 80B5 flange mounting is designed for equipment that relies on direct face registration rather than foot positioning. This can improve concentricity and save installation space in compact machinery layouts, particularly where the motor is bolted straight onto a gearbox or pump housing.

With a 19mm shaft and 200mm flange spigot, the motor follows established IEC dimensions for easier replacement and compatibility.

Frequently Asked Questions

What speed does a 4 pole motor run at?

A 4 pole electric motor operating on a 50Hz supply typically runs at around 1500rpm, with the actual full-load speed usually around 1400rpm due to motor slip.

Is B5 mounting suitable for direct gearbox connection?

Yes, B5 flange motors are commonly selected for direct mounting to IEC gearboxes and similar equipment because the flange and spigot help provide accurate concentric positioning.

What does IP55 protection mean?

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

Can this motor run on an inverter drive?

Many industrial AC motors can operate with inverter drives (VFDs), but suitability depends on the exact application, duty cycle, and motor specification.

What does B5 mounting mean?

B5 describes this motor’s IEC mounting arrangement and identifies how the motor is designed to be installed on compatible industrial equipment.
