This three-phase asynchronous induction motor covers frame sizes from 63 to 355 and power output ranging from 0.12kW to 315kW, covering miniature low-power precision drive to large-scale heavy-duty industrial drive scenarios. It adopts high-grade cold-rolled silicon steel sheet for stator lamination and die-cast aluminum rotor structure, featuring high operating efficiency, stable constant torque output and excellent low energy consumption performance. The outer ribbed integrated cast iron housing greatly strengthens forced air heat dissipation capacity, effectively restraining winding temperature rise during long-time continuous full-load operation and extending the service life of internal winding insulation and bearing components. Standard B5 vertical flange mounting structure achieves seamless docking and direct assembly with gear reducers, water pumps, centrifugal fans and general industrial transmission equipment, simplifying on-site installation layout and alignment work to shorten assembly time.
The motor delivers reliable heavy-start performance, smooth operation under no-load and full-load conditions, with low mechanical vibration and low operational noise. Customization options for working voltage (380V/400V/660V), rated frequency, protection grade and terminal box position are available, adapting to indoor closed workshops, open-air outdoor sites, dusty factories and high-humidity chemical workshop working environments. The maximum overload breakdown torque reaches 2.2 times the rated torque, which can fully cope with instantaneous impact load and locked-rotor load during heavy machinery startup, avoiding winding burnout caused by sudden load surge. All rolling bearings adopt high-temperature resistant lithium-based grease for long maintenance cycles, reducing daily upkeep costs for end users. The stator winding adopts vacuum pressure impregnation (VPI) paint dipping technology, which improves moisture-proof, oil-proof and anti-corrosion performance of the coil, suitable for long-term uninterrupted production operation. The terminal box adopts sealed rubber gaskets to prevent dust, water vapor and splashing liquid from entering the electrical cavity, improving operational safety in harsh working conditions. The dynamic balance calibration of the rotor strictly complies with international G2.5 balance grade standards to reduce long-term eccentric wear of the output shaft and bearings.
It serves as the universal prime mover for all kinds of general industrial supporting equipment, including direct drive matching for various gear reducers, clean water pumps, sewage pumps, centrifugal fans, Roots blowers, fixed belt conveyors, small industrial mixing tanks, machine tool auxiliary power units, automatic packaging machinery, food processing production lines, textile spinning and weaving equipment and agricultural irrigation machinery. High-power models over 110kW are specially deployed for mine main ventilation fans, large municipal water supply pumps, cement production auxiliary transmission rollers and metallurgical workshop auxiliary driving equipment. Premium high-efficiency versions are the core selection for energy-saving renovation projects of outdated production lines in chemical, building materials, environmental protection waste treatment and light manufacturing industries, helping enterprises cut long-term electricity consumption and operating costs. In addition, the motor can be matched with frequency converters to realize stepless speed regulation, which is widely used in energy-saving transformation of fan and water pump equipment, bringing remarkable electricity-saving benefits for industrial users. Small frame low-power motors are used for precision conveying equipment, testing instruments and small automation actuators, realizing compact and stable power drive for precision industrial equipment.
