This three-phase asynchronous induction motor drives the rotor to rotate through electromagnetic induction. It covers a power range of 0.06kW to 315kW with frame sizes from 56 to 355. It supports dual frequencies of 50/60Hz and multiple voltages such as 380V/400V. Three housing materials are available: aluminum alloy, cast iron and stainless steel. It features a drip-proof protection class and comes with a 12-month warranty. It has a wide range of applications, including water pumps, fans, air compressors, mixers, conveyor belts, washing machines, light industrial equipment, as well as residential and small commercial scenarios.
Slip Self-Adapts to Load
When the load increases, speed automatically drops a little and torque automatically follows. No extra controller is needed for self-regulation, simple and reliable.
Smooth Speed-Torque Curve
Speed changes gradually under load fluctuations, with no sudden stalling or violent shaking, keeping driven equipment running steadily.
Balanced Startup and Operation
Deep-bar or double-cage rotor design delivers high torque at startup and low slip, high efficiency during normal operation.
Shock-Resistant, Equipment-Friendly
Under sudden load spikes (e.g., crusher jams, conveyor overload), speed drops compliantly to absorb impact, protecting gears and couplings from damage.
Handles Short-Term Overload
Maximum torque reaches 2–3x rated torque, allowing it to ride through peak loads without tripping or shutting down.
Simple Structure, Easy Maintenance
No brushes, no excitation device, smooth startup, and virtually no routine maintenance needed - ideal for long continuous operation.

Q:How much does speed fluctuate with load changes?
A:Very little. Within the rated range, speed typically varies by only a few percent - negligible for pumps, fans, conveyors, and most ordinary equipment.
Q:Does high slip waste electricity?
A: During normal operation, slip is designed to be small for good efficiency. High slip at startup is intentional for high starting torque and drops once the motor is up to speed.
Q:Can the speed be adjusted manually?
A: Standard squirrel-cage motors run at a fixed speed - to adjust speed, pair them with a VFD. Wound-rotor motors can adjust speed via rotor resistance. In most industrial settings, VFDs are used for speed control.
