Monophase asynchronous motor is powered by single-phase AC supply. An auxiliary winding creates rotating magnetic field. Its rotor speed is always slightly lower than synchronous magnetic speed. Proven and mature construction for 220V residential and light industrial supply. Widely used for small pumps, ventilation fans, woodworking tools, auxiliary packaging machines and compact agricultural equipment. It is a steady-demand monophase asynchronous motor for export markets.
Asynchronous Slip Working Principle
Rotor runs slower than synchronous magnetic speed and generates torque via induced eddy current. No brushes or commutator for simple and reliable mechanics.
Integrated Main & Auxiliary Double Winding
Built with main winding plus auxiliary starting winding. Matched with capacitor for phase shift. Winding ratio can be adjusted to modify starting performance for different loads.
Standard IEC Frame Size
Frame, output shaft and mounting holes follow IEC standards. Machine builders can easily replace old asynchronous motors from different brands with simple matching.
No Contact Commutation Parts, Minimal Wear
Torque comes from electromagnetic induction without brush friction. It removes regular consumable replacement and lowers long-term failure rate.
Great Compatibility with Single-phase Mains
Three-phase power is not required. It works on regular 220V single-phase power in farms, workshops and shops, ideal for standalone small machinery.
Customizable Torque Profile
We can tune winding parameters and capacitor specifications to balance starting torque and operating efficiency for fans, pumps and light transmission loads.

Q: Why is it called monophase asynchronous motor?
A: It is asynchronous because rotor rotating speed is slower than the rotating magnetic field speed. It is powered by single-phase alternating current.
Q: Can monophase asynchronous motor run continuously at full rated load?
A: S1 duty models support continuous operation under rated load. For heavy fluctuating load, built-in thermal protector is recommended to prevent overheating.
Q: What will happen if the auxiliary winding fails on monophase asynchronous motor?
A: The motor will produce buzzing sound and fail to start, even if the main winding remains intact.
Q: What is the core difference between monophase asynchronous motor and three-phase asynchronous motor?
A: Monophase asynchronous motor needs auxiliary winding and capacitor to form rotating magnetic field. Three-phase asynchronous motor generates rotating magnetic field directly once connected to 3-phase supply and delivers higher starting torque.
Q: Can monophase asynchronous motor be customized for 110V power grid?
A: Yes, we can redesign windings for 110V 60Hz, mainly for North and South American markets.
