3 phase double speed induction motor is a pole-changing induction motor that delivers two fixed speeds by adjusting pole pairs of windings, different from standard single-speed three-phase asynchronous motors. Our 3 phase double speed induction motor is available in IE1, IE2 and IE3 efficiency classes, compliant with IEC standards and IP55 protection. Widely used for fans, hoists, dust removal units and material conveyors, it fits applications requiring high/low speed switching. Compatible with global 50Hz/60Hz industrial power supply, it is a popular pole-changing induction motor for engineering support.
Custom pole-changing winding design for two fixed speed outputs
The 3 phase double speed induction motor adopts dedicated pole-changing stator windings. It switches pole numbers via connection change to provide two separate rated speeds. This double speed induction motor has fixed speed ratio and the ratio can be preset before delivery. It is a frequently searched pole-changing motor for fans and lifting machinery.
Optional single winding tap or separate dual winding construction
3 phase double speed induction motor supplies two structural options: single winding tap and independent dual winding, to fit different starting torque requirements. Single winding version for light load, dual winding for heavy starting load. IE1, IE2, IE3 efficiency grades are available for both designs.
Built for interlock control logic to avoid winding damage
This 3 phase double speed induction motor supports electrical interlock between high speed and low speed circuits to prevent simultaneous power-on and winding burnout. It works with contactor control circuits and reduces wiring mistakes during on-site commissioning.
One motor replaces two power units to simplify machine layout
A 3 phase double speed induction motor removes the need for two separate motors. It saves installation space inside machines and simplifies assembly, which brings prominent benefits for mobile machines, dust fans and lifting mechanisms.
Constant speed output without slip fluctuation
Compared with VFD variable speed solutions, the 3 phase double speed induction motor maintains stable rated speed once switched. No speed drift occurs under changing load, ideal for processes that require steady high/low speed without speed variation.
Low control cost and easy maintenance for simple automation systems
3 phase double speed induction motor works with normal AC contactors instead of costly VFD drives. It cuts electrical control budget and is easy for field technicians to maintain, suitable for production lines with simple control logic and limited budget.

Q: Can I customize the speed ratio of the 3 phase double speed induction motor?
A: Yes. Common pole combinations for our 3 phase double speed induction motor include 2/4 pole, 4/6 pole and 4/8 pole. Select proper speed ratio according to working conditions, with IE1, IE2, IE3 efficiency optional.
Q: Can high speed and low speed circuits of double speed induction motor be energized at the same time?
A: No. Electrical interlock is mandatory for 3 phase double speed induction motor to avoid simultaneous activation. We provide standard interlock wiring diagrams for your electrical engineers.
Q: Does the double speed induction motor deliver the same torque at both speed settings?
A: No. The high speed and low speed modes of 3 phase double speed induction motor have different rated torque. Please share load requirements for both speeds so we recommend the correct winding design.
Q: Can I add a VFD later to get stepless speed regulation for double speed induction motor?
A: Not recommended. The windings of 3 phase double speed induction motor are designed for pole changing. Running with VFD easily leads to overheating and abnormal noise. Choose standard single speed induction motor if continuous variable speed is needed.
Q: What mounting types are available for your 3 phase double speed induction motor?
A: B3 foot mounted, B5 flange mounted and B14 small flange mounted are available. Standard IP55 cast iron housing, OEM service for nameplate, voltage and power ratio is supported.
