Amtecs 0.25kW 4 Pole Motor – 0.33HP 1500rpm IEC 71B14 Face Motor
The Amtecs 0.25kW 4 pole IE2 motor in IEC 71B14 format is built for industrial reliability where conveyors, pumps, fans, gearboxes, and general plant machinery. This face-mounted aluminium motor combines standard IEC mounting dimensions with efficient 3 phase performance.
Motor Overview
Because this product uses Face Motor, it is especially well suited to compact gearbox inputs and machinery where face mounting saves space. This 4 pole configuration is widely used where balanced all-round speed and torque are needed.
Why This Version?
This 0.25kW 4 pole Amtecs motor is intended for customers who need an IEC 71B14 motor rather than a generic substitute. The published frame, mounting, and shaft/flange detail (14mm Shaft x 105mm Spigot) 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 0.25kW 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 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 0.25kW motor?
When replacing a 0.25kW 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.
