240V Single Phase Motors — Quick Reference by Type
Single phase 240V motors are specified by starting mechanism — which determines starting torque, running characteristics and suitable load type. AIMS stocks single phase motors from TechTop in 0.18 kW to 3.0 kW across aluminium frame sizes 56 to 100.
| Motor Type | Starting Method | Best For | Starting Torque |
|---|---|---|---|
| Capacitor-Start (CSIR) | Centrifugal switch disconnects start capacitor after ~75% speed | Compressors, pumps, hard-starting loads | High (200-300% FLT) |
| Capacitor-Start Capacitor-Run (CSCR) | Two capacitors — start cap disconnects, run cap stays in | Higher efficiency & higher torque — premium compressors, hard-start applications | Very High (300-400% FLT) |
| Permanent Split Capacitor (PSC) | Single run capacitor stays in continuously | Fans, blowers, light-load continuous duty | Low (50-100% FLT) |
| Split-Phase | Higher-resistance start winding switched out after start | Light loads — fans, small pumps, easy-starting equipment | Low-Moderate (100-200% FLT) |
Synchronous speeds: 2-pole = 3000 RPM, 4-pole = 1500 RPM (most common), 6-pole = 1000 RPM. For the broader three-phase range, see 415V three-phase motors. For motor mounting hardware, see motor mounts and anti-vibration mounts.
Single Phase Electric Motors — 240V Industrial
AIMS Industrial stocks TechTop 240 V single-phase electric motors for applications operating on standard Australian single-phase supply. Single-phase motors are the practical solution for workshops, small machinery, light pumps and any application where three-phase power is not available. Manufactured to AS/NZS 1359 / IEC 60034 standards across the range.

TML aluminium single-phase motors
The TechTop TML series covers general-purpose single-phase applications in aluminium-frame construction. Lightweight, corrosion-resistant and IP55 rated, TML motors suit workshop equipment, small pumps, fans and general machinery drives. The TML Dual Voltage variant provides flexibility between 240 V and 415 V supply by switching internal winding configuration — useful for OEM equipment that may operate across different site power configurations, or for workshops where future three-phase upgrade is anticipated.
TMY series
The TechTop TMY 240 V aluminium motor series provides capacitor-start, capacitor-run (CSCR) performance for applications requiring higher starting torque. The TMY is the correct selection for compressors, pumps and equipment with high inertia or high break-away torque loads where a standard single-phase split-phase motor does not provide sufficient starting capability. CSCR motors deliver up to 3-4× the starting torque of permanent-split-capacitor (PSC) motors at the cost of slightly higher complexity.
Applications & selection
Single-phase 240 V motors are used in workshop equipment, small pumps, fans, bandsaws, grinders and general machinery where three-phase power is unavailable. When specifying:
- Verify starting method — compressors and reciprocating pumps demand a motor with high starting torque (CSCR or CSIR); fans and centrifugal pumps will run on PSC or split-phase
- Check IP rating against environment — IP55 (TechTop standard) suits indoor workshop use; IP56 or higher for outdoor or washdown
- Mounting — B3 (foot mount), B5 (flange) and B14 (face flange) determine how the motor attaches to the driven equipment
- Pole count drives speed — 2-pole runs ~2,850 rpm, 4-pole runs ~1,440 rpm, 6-pole runs ~960 rpm at 50 Hz

People Also Ask — Single Phase Electric Motors
Q: What supply voltage do single-phase motors run on in Australia?
Single-phase motors at AIMS run on standard Australian 240 V single-phase mains at 50 Hz — the supply available in most workshops, sheds and light-commercial sites where three-phase power isn't connected. They're the practical choice for small machinery, light pumps, fans and general workshop equipment. Where three-phase 415 V is available it's usually preferred for motors above about 3 kW, because three-phase motors are simpler, more efficient and have higher starting torque. See our three-phase motors range for the 415 V option.
Q: How do I convert motor power between kW and horsepower?
Australian motors are rated in kilowatts (kW) but many older machines and imported specifications quote horsepower (HP). One HP is about 0.746 kW. The common single-phase motor ratings map as: 0.18 kW is about 0.25 HP, 0.37 kW about 0.5 HP, 0.55 kW about 0.75 HP, 0.75 kW about 1 HP, 1.1 kW about 1.5 HP, 1.5 kW about 2 HP, and 2.2 kW about 3 HP. When replacing a motor, match the kW rating and the frame size rather than converting loosely, and check the RPM and mounting as well.
Q: Which starting method do I need — capacitor-start, PSC or split-phase?
The starting method sets how much torque the motor develops to get the load moving. Capacitor-start (CSIR) and capacitor-start capacitor-run (CSCR) develop high starting torque for hard-starting loads such as compressors and reciprocating pumps. Permanent split capacitor (PSC) and split-phase motors develop lower starting torque and suit easy-starting loads such as fans, blowers and centrifugal pumps. Matching the starting method to the load is the single most important single-phase selection decision — an under-torqued motor stalls or trips on start.
Q: What brand of single-phase motor does AIMS stock?
AIMS stocks TechTop single-phase motors — the TML aluminium-frame general-purpose series and the TMY capacitor-start capacitor-run series for higher starting torque. TechTop is AIMS's motor brand across single-phase and three-phase, built to AS/NZS 1359 / IEC 60034 with IP55 sealing as standard. The working range is 0.18 kW to 3.0 kW across frame sizes 56 to 100 ex-stock, with broader frame sizes, higher IP ratings and non-standard voltages available to order. See the full TechTop range.
Q: What is the difference between foot mount and flange mount motors?
The mounting type sets how the motor attaches to the driven equipment. Foot mount (B3) bolts down through feet on the motor base — the general-purpose choice for belt drives and bolt-down machinery. Flange mount (B5, with a large spigot flange, or B14, with a smaller face flange) bolts the motor face directly to a gearbox, pump or machine housing for a close-coupled drive. Match the mounting to the equipment — many motors are available in a combined foot-and-flange (B35) mounting for flexibility. See electric motors for the wider range.
Q: What IP rating do I need for a single-phase motor?
The IP (Ingress Protection) rating sets how well the motor resists dust and water. IP55 — the TechTop standard — suits general indoor workshop and light-industrial use, resisting dust and low-pressure water jets. For outdoor mounting, washdown areas or wet environments, specify IP56 or higher. For food-processing washdown, a higher-sealed or stainless motor is the correct choice. Match the IP rating to where the motor will actually live, not just the indoor default.
Q: How does pole count affect motor speed?
The number of poles sets the synchronous speed on 50 Hz supply: a 2-pole motor runs near 2,850 rpm, a 4-pole near 1,440 rpm, and a 6-pole near 960 rpm (actual full-load speed sits slightly below synchronous because of slip). Four-pole is the most common general-purpose speed. Choose the pole count to suit the driven equipment's speed — a belt or gear drive can then fine-tune the final output speed. For belt-drive speed matching see our pulley speed ratio guide.
Q: Can I run a single-phase motor where I'd normally use three-phase?
For smaller loads, yes — single-phase 240 V motors cover most applications up to about 3 kW where three-phase isn't available. Above that, three-phase becomes the practical choice because single-phase motors get large, draw high running current and have limited starting torque at higher powers. An alternative is a variable frequency drive, which on some models runs a three-phase motor from a single-phase supply. See variable frequency drives and our electric motor guide.
