YXKK400-4G T1 Three-phase Asynchronous Motor 400 Kw 1500rpm ip54

Brief Introduction

As a flagship power apparatus crafted by Xi'an SIMO Motor Co., Ltd., the YXKK series motor 400 kw constitutes an elite high-tension three-phase asynchronous prime mover engineered to cater to arduous industrial operating conditions, adhering rigorously to domestic and international authoritative manufacturing benchmarks. This 400 kw motor amalgamates sophisticated heat dissipation, insulation and bearing technologies, furnishing consistent, energy-efficient and long-lasting power propulsion for large-scale industrial installations across diverse verticals.

This motor operates at a nominal voltage of 10,000 V with a rated current of 31.7 A, revolving at a synchronous speed of 1485 r/min under 50 Hz grid frequency. It boasts a power factor of 0.87 and attains an exceptional energy efficiency coefficient of 94.1%, conforming to top-tier energy conservation criteria to substantially curtail enterprises' long-term electrical expenditure. Its stator windings are encapsulated with Class F thermal insulation, sustaining a thermal threshold of 155°C to mitigate degradation and burnout induced by prolonged uninterrupted operation. Configured with star connection and S1 continuous duty rating, it facilitates non-disrupted steady functioning, perfectly aligning with round-the-clock production workflows that demand uninterrupted power conveyance.

In respect of thermal management, the motor 400 kw integrates IC611 air-water compound cooling architecture. The embedded air-water heat exchanger dissipates operational heat via circulating coolant; operators are mandated to channel designated circulating cooling water prior to commissioning, as stipulated on the bilingual caution plaque, to preclude winding overheating and permanent impairment. Boasting an IP54 ingress protection rating, it repels particulate contaminants and splashing moisture, rendering it resilient against abrasive, humid and thermally volatile factory surroundings. Adopting IM B3 horizontal foot-mounted configuration, the universal industrial installation paradigm, it streamlines on-site assembly, coaxial calibration and routine overhaul.

For bearing assembly, the drive terminus is fitted with NU224ECM cylindrical roller bearing, whereas the non-drive terminus adopts a 6224/C3 deep-groove ball bearing. This dual-bearing composite withstands formidable radial and axial load stresses. Units furnished with compound grease-lubricated bearings require external circulating grease supply to be pre-connected prior to activation, forestalling abrasive bearing attrition stemming from inadequate lubrication. The aggregate unit mass reaches 3320 kg, with an ambient operational temperature bandwidth spanning -40°C to 40°C and a permissible altitude ceiling of 2500 meters, enabling seamless deployment in highland and frigid zones without supplementary structural modification.

The motor 400 kw incorporates comprehensive intrinsic safety protocols exhaustively delineated on the bilingual warning plaque. As a 2-pole rotary unit, its rotational trajectory must strictly comply with directional indicator signage. Heavy-load reduced-voltage startup necessitates stringent parametric governance, for starting torque diminishes quadratically alongside voltage, and protracted startup duration incurs irreversible winding thermal degradation. Ground-shorted winding operation is categorically prohibited; perfect coaxial collinearity must be secured during coupling engagement with driven machinery to eradicate resonant vibration and mechanical structural deterioration during operation. All safety protocols are inscribed in both Chinese and English, facilitating standardized manipulation for global multinational operators.

Versatile in deployment, this motor acts as a robust power core for industrial fluid pumps, heavy-duty compressors, mining haulage conveyors, metallurgical smelting apparatus and chemical processing plant machinery. Accredited with CE conformity certification, it satisfies European Union market access prerequisites, enabling seamless exportation to worldwide industrial territories. Backed by SIMO's bespoke after-sales technical ecosystem, every unit undergoes stringent pre-delivery factory validation, with exclusive serial coding granting full production traceability. Synthesizing stellar energy efficiency, formidable environmental adaptability and all-encompassing safeguarding mechanisms, the YXKK series motor 400 kw strikes an optimal equilibrium between premium performance and operational economy, emerging as the preeminent high-voltage motor solution for global industrial clientele pursuing stable, low-carbon power transmission infrastructure.
