An asynchronous motor (also known as an induction motor) is an AC electric motor that generates torque through the interaction between the stator's rotating magnetic field and the induced current in the rotor. The rotor speed is always slightly lower than the synchronous speed, hence the name "asynchronous." This product line covers mainstream models such as MS and Y2, with frame sizes from 56 to 355 and a power range of 0.06kW to 315kW. It supports dual-frequency (50/60Hz) three-phase power supply and is widely used in water pumps, fans, compressors, mixers, conveyors, light industry, and civil applications.
Simple and Reliable Structure
The squirrel-cage rotor design eliminates commutators and brushes, resulting in fewer moving parts, lower failure rates, and the ability to run continuously for extended periods.
Wide Power Range
Available from 0.06kW micro motors up to 315kW high-power models, covering frame sizes 56 through 355 for easy selection and matching.
Multiple Housing Options
Three housing materials are available: aluminum, cast iron, and stainless steel, catering to lightweight, high-strength, and corrosion-resistant requirements respectively.
Low Operating Cost
No brush maintenance required, minimal routine upkeep, long service life, and lower total cost of ownership compared with DC and synchronous motors.
Stable Starting Performance
Sufficient starting torque under three-phase power for direct driving of constant-torque loads such as fans and pumps; smooth speed regulation is achievable when paired with a VFD.
Strong Environmental Adaptability
Drip-proof enclosure design, support for multiple voltage levels (380V/400V, etc.), and 50/60Hz dual-frequency compatibility make it suitable for different grid standards worldwide.

Q: What is the difference between an asynchronous motor and a synchronous motor?
A: An asynchronous motor's rotor speed is lower than the synchronous speed, generating torque through electromagnetic induction. It has a simple structure and low cost. A synchronous motor runs at exactly the synchronous speed, requires additional excitation, offers higher efficiency but is more complex and expensive. Asynchronous motors are generally preferred for general industrial driving.
Q: How do I choose between aluminum and cast iron housings?
A: Choose aluminum for low-power, weight-sensitive applications; cast iron for high-power industrial environments with vibration or impact; and stainless steel for food, chemical, or other corrosion-prone settings.
Q: What is the warranty period?
A: The standard warranty is 12 months from the date of shipment. Any quality issues not caused by misuse are covered by free repair or replacement.
