Amtecs 0.37kW 8 Pole Motor – 0.5HP 750rpm IEC 90SB14 Face Motor

The 0.37kW 8 pole Amtecs motor with IEC 90SB14 mounting is intended for industrial users who need a reliable, easy-to-fit, and energy-efficient 3 phase motor for conveyors, indexing systems, slow-speed drive duties, and geared assemblies.

---

Motor Overview

Its Face Motor arrangement is intended for compact gearbox inputs and machinery where face mounting saves space. 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 90SB14 motor rather than a generic substitute. The published frame, mounting, and shaft/flange detail (24mm Shaft x 140mm 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 face 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 compact direct mounting applications?

Yes, the B14 face mount arrangement is widely used where a compact flange fit is needed and space is more restricted than on full B5 flange-mounted applications.

What should I check before replacing a 0.37kW motor?

When replacing a 0.37kW motor, check the frame size, pole count, B14 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 B14 mounting mean?

B14 is the IEC face-mounted arrangement, commonly used where a compact flange connection is needed on compatible gearboxes, pumps, and OEM machinery.
