Buy Single Phase Motors Online in Australia
Single-phase electric motors run on standard Australian 240V single-phase power — the supply found in almost every workshop, shed, farm building and light-commercial site, whether or not three-phase has been connected. They're the practical choice for smaller pumps, fans, compressors and general workshop machinery where running three-phase supply to a site isn't justified. AIMS Industrial stocks TechTop 240V aluminium-frame single-phase motors across two starting-method series — TMY and TML (including a 240V/480V dual-voltage TML variant) — covering 0.06 kW to 3.7 kW.

How to Choose a Single-Phase Motor
Starting method: PSC or CSCR
The starting method is the main practical difference between AIMS's two single-phase series. The TMY is a Permanent Split Capacitor (PSC) design — a single run capacitor stays in circuit continuously, giving smooth, lightweight running with moderate starting torque. TechTop positions the TMY for fan and pump applications where light weight and running performance matter more than break-away torque, and its multi-mount design lets the feet be repositioned to either side for a side-mounted terminal box. The TML is a Capacitor-Start Capacitor-Run (CSCR) design — using a start capacitor and a separate run capacitor for higher starting torque — suited to general-purpose applications where getting a harder-to-start load moving is the priority, and it pairs well with aluminium gearbox applications. If your load has meaningful break-away torque — a loaded conveyor, a piston compressor, a positive-displacement pump — the CSCR TML is the safer starting point; for fans, centrifugal pumps and other easy-starting loads, the lighter PSC TMY is a good fit.
Sizing the kW rating
Match the motor's kW rating to the absorbed power your driven equipment needs at its duty point — not a rough round-up. If you're replacing an existing single-phase motor, matching the kW, pole count and mounting already on the old nameplate is the simplest and most reliable approach. Australian motors are rated in kilowatts; if you're working from an older or imported spec in horsepower, 1 HP is approximately 0.746 kW.
Poles and running speed
Both the TMY and TML series are available in 2, 4 and 6 pole windings, which set the synchronous speed on 50 Hz supply: 2-pole runs near 2,850 rpm, 4-pole (the most common general-purpose speed) near 1,440 rpm, and 6-pole near 960 rpm, with actual full-load speed sitting slightly below synchronous due to slip.
Mounting
Both series are available in foot mount (B3), flange mount (B5 or the smaller-face B14A/B14B), and combined foot-and-flange configurations. B3 bolts down through feet on the motor base — the general-purpose choice for belt-driven equipment. B5/B14 flange mounting bolts the motor face directly to a pump or gearbox housing for a close-coupled drive. Match the mounting to what the driven equipment expects; the foot-and-flange combinations give you the option to change mounting style later without swapping the motor.
240V or the 240V/480V dual-voltage option
The standard TMY and TML motors run on 240V single-phase. The TML Dual Voltage variant is wired for 240V/480V single-phase operation and is available from 1.5 kW to 3.7 kW — useful where equipment or site wiring is set up for the higher voltage tap rather than standard 240V. It remains a single-phase motor; it does not convert between single-phase and three-phase supply.
Verified Brand
AIMS stocks a single brand of single-phase electric motor: TechTop, across the TMY (PSC) and TML (CSCR, including dual-voltage) series described above. TechTop is also AIMS's brand for three-phase motors, so parts, documentation and support stay consistent whichever supply you're specifying for.

Frequently Asked Questions
What's the difference between the TechTop TMY and TML single-phase motors?
The TMY is a Permanent Split Capacitor (PSC) motor built for fan and pump applications where light weight and smooth running matter most. The TML is a Capacitor-Start Capacitor-Run (CSCR) motor built for higher starting torque in general-purpose applications, including driving aluminium gearboxes. If your load starts under load — a compressor, a loaded conveyor — start with the TML; for easy-starting loads like fans and centrifugal pumps, the TMY is the lighter, simpler option.
What is the TML Dual Voltage motor, and do I need it?
It's a 240V/480V single-phase version of the TML CSCR motor, available from 1.5 kW to 3.7 kW. It suits equipment or sites wired for the higher voltage tap. It's still a single-phase motor — it doesn't switch between single-phase and three-phase operation, so it isn't a substitute for a genuine three-phase supply.
How do I convert horsepower to kW when replacing an older motor?
One horsepower is approximately 0.746 kW. When replacing a motor, match the kW rating, pole count and mounting from the old nameplate rather than converting loosely — the pole count and mounting determine whether the new motor will actually fit and run the driven equipment at the right speed.
What mounting options are available on single-phase motors at AIMS?
Both the TMY and TML series come in B3 foot mount, B5 flange, B14A/B14B face flange, and combined foot-and-flange configurations. B3 suits belt-driven equipment bolted to a base; B5/B14 flange mounting bolts the motor face directly to a pump or gearbox for a close-coupled drive.
What pole counts and running speeds are available?
Both series are available in 2, 4 and 6 pole windings. On 50 Hz supply that gives synchronous speeds of roughly 2,850 rpm (2-pole), 1,440 rpm (4-pole, the most common) and 960 rpm (6-pole), with actual full-load speed slightly below synchronous due to slip.
At what point should I move from single-phase to three-phase power?
Single-phase 240V motors at AIMS cover applications up to 3.7 kW. Beyond that, three-phase becomes the more practical choice — three-phase motors are simpler, draw lower running current for the same output, and don't rely on a starting capacitor. See our three-phase motors range, or a variable frequency drive where you need to run a three-phase motor from a single-phase supply.
What brand of single-phase motor does AIMS stock?
AIMS stocks TechTop single-phase motors — the PSC TMY series and the CSCR TML series, including the 240V/480V dual-voltage TML variant. TechTop is AIMS's motor brand across single-phase and three-phase. See the full TechTop range.
