Motor Overview

This version is supplied in Foot Mount format so it can be installed on base-mounted machine beds and fabricated steel structures. This 4 pole configuration is widely used where balanced all-round speed and torque are needed.

---

Why This Version?

This 0.37kW 4 pole Amtecs motor is intended for customers who need an IEC 71B3 motor rather than a generic substitute. The published frame, mounting, and shaft/flange detail (14mm Shaft) make it easier to match to replacement and OEM requirements.

Frequently Asked Questions

What speed does a 4 pole motor run at?

A 4 pole electric motor operating on a 50Hz supply typically runs at around 1500rpm, with the actual full-load speed usually around 1400rpm 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 standard industrial 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 0.37kW motor?

When replacing a 0.37kW 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.
