Amtecs 0.25kW 8 Pole Motor – 0.33HP 750rpm IEC 80B3 Foot Mount

For replacement motor duties and new machinery builds, this Amtecs 0.25kW 8 pole motor offers a practical IEC 80B3 mounting solution with IP55 protection, TEFC construction, and IE2 efficiency.

---

Motor Overview

Its Foot Mount arrangement is intended for base-mounted machine beds and fabricated steel structures. This 8 pole configuration is suited to applications that need very low motor speed and smooth running.

---

Why This Version?

This 0.25kW 8 pole Amtecs motor is intended for customers who need an IEC 80B3 motor rather than a generic substitute. The published frame, mounting, and shaft/flange detail (19mm Shaft) make it easier to match to replacement and OEM requirements.

---

Typical Applications

• Replacement motor duties where IEC interchangeability matters
• OEM installations requiring a standard foot mount motor
• Slow-speed industrial applications matched to 8 pole speed characteristics
• General 3 phase machinery including conveyors, indexing systems, slow-speed drive duties, and geared assemblies

Frequently Asked Questions

What speed does a 8 pole motor run at?

A 8 pole electric motor operating on a 50Hz supply typically runs at around 750rpm, with the actual full-load speed usually around 680–720rpm 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 very low running speed, reliable continuous-duty operation, and IEC interchangeability are important.

Is this motor suitable for pulley or coupling drives?

Yes, the B3 foot mount arrangement is commonly used for pulley-driven, chain-driven, and coupling-driven machinery where the motor is mounted directly onto a base or frame and aligned mechanically during installation.

What should I check before replacing a 0.25kW motor?

When replacing a 0.25kW motor, check the frame size, pole count, B3 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 B3 mounting mean?

B3 is the standard IEC foot-mounted arrangement, designed for motors that bolt down to a machine bed, baseplate, skid, or fabricated frame.
