Three-phase motors

Three-phase motor ratings

3 kW 4 pole three-phase motors

102 motors are registered for supply in Australia at 3 kW 4 pole, from 40 different brands. A 4 pole motor runs at a synchronous speed of 1,500 rpm on a 50 Hz supply. Registration means the motor may be supplied here. It is not a statement that it fits your application.

7 frame sizes · 15 recorded voltages · 31 mounting arrangements

Frame sizes at this rating

IEC: 100, 100L, 100LC, 112M, 112S, 132S

The number is the shaft centre height in millimetres and the letter is the frame length. It fixes how high the shaft sits and where the foot holes are, so a 132M from one manufacturer mounts like a 132M from another.

Standard unclear: 100AP

Recorded in a form that does not place them confidently against either system — a NEMA-style suffix without the word NEMA, or a dual-frame designation such as 213/5T. Check the standard against the manufacturer's drawing before treating any of these as a centre height in millimetres.

Synchronous speed

1,500 rpm — 1500 rpm at 50 Hz, from 4 poles.

Full-load speed is lower than this by the motor's slip, and slip is not recorded in the register. Read it from the nameplate of the motor you are replacing.

Efficiency spread

Full-load efficiency across these registrations runs from 84.10% to 91.92%.

Over a motor's working life, running cost usually dwarfs purchase price, so this spread is worth more attention than it normally gets.

Every 3 kW 4 pole motor registered for supply in Australia, by brand. Enclosure and mounting are often recorded for a registration family rather than one model — see the note below the table.

What this page establishes, and what it does not

  • Established: every motor listed is registered for supply in Australia at 3 kW 4 pole, and the frame, enclosure and efficiency shown are what its registration states.
  • Established: a 4 pole motor has a synchronous speed of 1,500 rpm at 50 Hz. That is arithmetic, not a measurement.
  • Read carefully: a registration often covers a family of motors rather than one part number. 73 of these registrations list several voltages and 90 list several mounting arrangements — meaning a compliant variant exists in that family, not that the model shown is that variant.
  • Not established: that any motor here bolts into your application. Shaft diameter, shaft length and keyway are not in the register, and neither is terminal box position.
  • Not established: that a motor is currently available, or at what price. The register records permission to supply, not stock.
  • Not in this dataset: full-load speed, starting current, duty rating, and suitability for inverter operation.
