Brief Introduction

The 12 pole induction motor, model YJTKS630-12TH, represents a high-capacity variable-frequency asynchronous motor engineered and fabricated by Xi'an AIMIN Motor Co., Ltd. This heavy-duty variable-speed prime mover is designated for uninterrupted S1 continuous duty, meticulously optimized to accommodate sophisticated variable-speed operating regimes prevalent in energy, petrochemical, metallurgical and water infrastructure sectors. Furnished with IC86W air-water cooling architecture and IP55 ingress protection rating, the unit boasts superior thermal dissipation capacity amid prolonged full-load operation. It incorporates Class 155 thermal insulation infrastructure, capable of withstanding voltage transients induced by frequency converters and prolonging operational longevity amid recurrent speed modulation cycles.

Customized to satisfy overseas project specifications, this motor accommodates bespoke electrical parameters encompassing 440V nominal stator voltage and 60Hz base frequency. At the rated 60Hz operational threshold, the motor attains 900kW power output alongside a rated rotational velocity of 595 r/min while sustaining a steady power factor of 0.76. Its design facilitates flexible frequency modulation spanning 5–60Hz, delivering constant torque performance within the low-frequency spectrum and constant power characteristics at elevated frequencies. The robust B3 horizontal mounting configuration, paired with heavy-duty NU238ECM and 6336/C3 bearings, substantially elevates shaft load bearing capacity, rendering it ideal for direct coupling with pumps, compressors and large-scale fans. Rigorous alignment during commissioning mitigates vibration and acoustic emission throughout extended service cycles.

As a resilient 12 pole induction motor solution for international engineering undertakings, the unit adheres rigorously to JB/T 10315.1 industrial specifications. It functions reliably within an ambient temperature bandwidth of -15℃ to 40℃ and maintains stable performance at elevations up to 1000 meters. Bespoke engineering services are available for clients requiring tailored 440V, 60Hz voltage and frequency configurations to align with regional grid criteria across Southeast Asia, North America and other global territories. In contrast to fixed-speed counterparts, this variable-frequency motor achieves substantial energy conservation by modulating rotational speed in accordance with real-time load requirements.

For large-scale low-speed drive applications, this 12 pole induction motor distinguishes itself with sustained low-speed torque delivery, superior operational efficiency and formidable overload endurance. AIMIN furnishes comprehensive technical documentation, factory acceptance testing and full lifecycle aftersales support for all custom-engineered 440V 60Hz variable-frequency motors, delivering premium heavy-duty drive solutions for worldwide industrial variable-speed transmission ecosystems.
