Brief Introduction

Fabricated by Xi'an SIMO Motor Co., Ltd., the YJTKK portfolio constitutes a sophisticated high-voltage variable-frequency prime mover engineered for arduous industrial sectors encompassing metallurgy, mineral exploitation, chemical processing, thermal power generation and hydraulic engineering. The 3 phase 4 pole squirrel cage induction motor exemplified by the YJTKK355-4 model functions as a flagship high-power variant within this product spectrum, furnishing consistent speed-modulated output for oversized blowers, centrifugal pumps, air compressors and process machinery necessitating recurrent velocity modulation. Conforming to corporate specification Q/XD.510.316, this motor undergoes stringent factory validation and bears CE accreditation, aligning with domestic regulatory codes and cross-border export benchmarks for industrial rotating equipment.

The YJTKK355-4 operates at a nominal high tension of 10000V, boasting a rated power of 450kW, rotational velocity of 1485 revolutions per minute, power factor of 0.86 and peak energy efficiency of 92.9%, attaining premium Class F high-efficiency criteria to curtail long-term operational power overhead for manufacturing conglomerates. It adopts star wiring topology paired with S1 continuous-duty rating, facilitating uninterrupted round-the-clock full-load operation. Its frequency-modulation compatibility spans 5Hz to 50Hz, enabling flexible velocity calibration synchronized with high-voltage frequency inverters. In terms of thermal governance, the motor incorporates an IC66 closed air-to-air cooling architecture, segregating internal heat-exchange airflow from ambient air circulation. This configuration impedes ingress of particulate contaminants, humid vapor and corrosive fumes into the winding cavity, substantially prolonging the service lifespan of electromagnetic coils. A multitude of heavy-industrial stakeholders opt for the 3 phase 4 pole squirrel cage induction motor setup on account of its robust squirrel-cage rotor devoid of slip rings and carbon brushes, delivering minimal recurring maintenance and formidable immunity to repetitive frequency-conversion mechanical shocks. It features IP54 ingress protection to obstruct solid debris infiltration and liquid splashes, alongside 155°C Class F thermal insulation resilient to temperature elevation induced by variable-frequency modulation. The drive terminal is fitted with SKF NU222ECM bearings, whereas the non-drive terminal employs 6222/C3 bearings, endowing the unit with exceptional load-bearing capability, vibration attenuation performance and abrasion resistance. The equipment sustains stable functionality within an ambient temperature bandwidth of -15°C to 40°C and elevations under 1000 meters, accommodating rugged plant premises plagued with thermal volatility and particulate contamination.

In contrast to conventional fixed-speed high-voltage motors, the YJTKK range receives targeted optimization to counteract harmonic perturbation stemming from frequency conversion. The stator windings undergo specialized anti-harmonic insulation refinement to preclude insulation degradation and dielectric breakdown triggered by pulse voltage emanating from inverters. Each motor is allocated a unique production serial number enabling comprehensive full-lifecycle traceability, streamlining aftermarket troubleshooting, spare part interchange and quality auditing protocols. All finished units complete rigorous no-load commissioning, insulation resistance testing and vibration screening prior to shipment to ensure homogeneous operational performance. Amid global energy-conservation retrofits across high-power-consuming industries, international industrial procurement projects consistently designate the 3 phase 4 pole squirrel cage induction motor belonging to the YJTKK roster. Its amalgamation of rugged squirrel-cage mechanics, high-efficiency air-to-air heat dissipation, extensive frequency adaptability and robust mechanical rigidity cements its standing as a premium variable-frequency power solution for high-demand industrial applications operating in austere working conditions worldwide.
