Amtecs 0.55kW 2 Pole Motor – 0.75HP 3000rpm IEC 71B5 Flange Motor

The 0.55kW 2 pole Amtecs motor with IEC 71B5 mounting is intended for industrial users who need a reliable, easy-to-fit, and energy-efficient 3 phase motor for fans, blowers, saws, polishing equipment, and direct-drive machinery.

---

Motor Overview

The flange-mounted design makes this motor suitable for direct mounting to pumps, gearboxes, and flange-driven machinery. This 2 pole configuration is typically chosen where higher shaft speed is required.

---

Why This Version?

This 0.55kW 2 pole Amtecs motor is intended for customers who need an IEC 71B5 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.

---

Typical Applications

• Replacement motor duties where IEC interchangeability matters
• OEM installations requiring a standard flange motor motor
• High-speed industrial applications matched to 2 pole speed characteristics
• General 3 phase machinery including fans, blowers, saws, polishing equipment, and direct-drive machinery

Frequently Asked Questions

What speed does a 2 pole motor run at?

A 2 pole electric motor operating on a 50Hz supply typically runs at around 3000rpm, with the actual full-load speed usually around 2800–2900rpm due to motor slip.

What is this 0.55kW motor commonly used for?

This motor is commonly used on small conveyors, fans, pumps, geared assemblies, packaging equipment, and compact OEM machinery where higher 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 0.55kW motor?

When replacing a 0.55kW 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.
