Motor Overview

This version is supplied in Foot & Flange Motor format so it can be installed on applications where both flange location and foot support are useful. This 6 pole configuration suits applications where a slower-running motor is preferred.

---

Why This Version?

This 0.25kW 6 pole Amtecs motor is intended for customers who need an IEC 71B35 motor rather than a generic substitute. The published frame, mounting, and shaft/flange detail (14mm Shaft x 160mm Spigot) make it easier to match to replacement and OEM requirements.

---

Frequently Asked Questions

What speed does a 6 pole motor run at?

A 6 pole electric motor operating on a 50Hz supply typically runs at around 1000rpm, with the actual full-load speed usually around 930–970rpm due to motor slip.

What is this 0.25kW motor commonly used for?

This motor is commonly used on small conveyors, fans, pumps, geared assemblies, packaging equipment, and compact OEM machinery where lower running speed, reliable continuous-duty operation, and IEC interchangeability are important.

Why would I choose a B35 motor?

A B35 foot and flange motor is commonly chosen where the motor needs both a secure base-mounted position and a full flange interface to the driven equipment.

What should I check before replacing a 0.25kW motor?

When replacing a 0.25kW motor, check the frame size, pole count, B35 mounting arrangement, shaft dimensions, supply voltage, and the mechanical fit to the existing machine before ordering.

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, cable length, and motor specification.

What does B35 mounting mean?

B35 combines foot mounting with a B5 flange, making it a practical choice where both base fixing and a full flange connection are required.
