Amtecs 0.37kW 8 Pole Motor – 0.5HP 750rpm IEC 90SB5 Flange Motor

This Amtecs 0.37kW electric motor uses a 8 pole winding and IEC 90SB5 mounting arrangement, making it a strong option for conveyors, indexing systems, slow-speed drive duties, and geared assemblies. It is designed for continuous industrial service with IE2 efficiency and IP55 protection.

Motor Overview

Because this product uses Flange Motor, it is especially well suited to direct mounting to pumps, gearboxes, and flange-driven machinery. This 8 pole configuration is suited to applications that need very low motor speed and smooth running.

Why This Version?

This 0.37kW 8 pole Amtecs motor is intended for customers who need an IEC 90SB5 motor rather than a generic substitute. The published frame, mounting, and shaft/flange detail (24mm Shaft x 200mm Spigot) make it easier to match to replacement and OEM requirements.

Typical Applications

• Replacement motor duties where IEC interchangeability matters
• OEM installations requiring a standard flange motor 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 0.37kW 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 direct flange mounting?

Yes, the B5 flange mount arrangement is intended for direct mounting onto compatible driven equipment where a full flange connection is required.

What should I check before replacing a 0.37kW motor?

When replacing a 0.37kW motor, check the frame size, pole count, B5 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 B5 mounting mean?

B5 is the standard IEC flange-mounted arrangement, designed for motors that mount directly to compatible gearboxes, pumps, fan housings, and other flanged industrial equipment.
