YL4503-12 Three-phase Asynchronous 12 Pole Motor Rpm 495 380V

Brief Introduction

Developed and manufactured by Xi'an SIMO Motor Co., Ltd., the SIMO YL vertical three-phase asynchronous motor constitutes a high-caliber vertical driving apparatus engineered for arduous industrial ancillary equipment. Serving as a sophisticated tailor-made driving alternative for large pumps, heavy-duty blowers, water purification infrastructure and mining auxiliary mechanisms, this product lineup encompasses diverse frame specifications and pole configurations. Its flagship variant, YL4503-12, emerges as a quintessential 12 pole motor rpm solution prevalently deployed in low-velocity, high-torque industrial applications. Rooted in SIMO's decades-long prowess in motor research and development, the product abides rigorously by international fabrication norms, acquiring CE accreditation and comprehensive performance authentication to accommodate worldwide industrial sourcing criteria.

Centered on the designated YL4503-12 motor as the showcased specimen, its elaborate electrical metrics epitomize the series' rigorous design philosophy. The nominal operational frequency registers at 50 hertz; the stator rated voltage stands at 380 volts, paired with a rotor voltage of 539.7 volts and a rated current of 495 amperes. Its nominal output power attains 250 kilowatts, complemented by a power factor of 0.76 and Class 50 energy efficiency, striking an optimal equilibrium between energy expenditure and output efficacy during prolonged operation. Classified under S1 continuous duty cycle, the motor sustains uninterrupted long-duration functioning without performance degradation. Equipped with IP23 ingress protection and IC01 cooling architecture, it accommodates conventional indoor industrial surroundings with a maximal ambient temperature ceiling of 40 degrees Celsius. Internal windings adopt Class F insulation with a thermal threshold of 155 degrees Celsius, substantially elevating resilience against thermal escalation, overload shocks and voltage volatility. Front and rear pivots adopt NU228ECM heavy-duty roller bearings, specially reinforced to withstand formidable axial tension, an indispensable refinement for vertical mounting subject to sustained axial stress induced by gravitational pull and mechanical oscillation.

In respect of mechanical framework and manufacturing craftsmanship, SIMO enforces stringent oversight across all production workflows to secure operational dependability. The motor housing adopts high-tensile cast iron via integral casting, efficiently mitigating mechanical distortion triggered by chronic vibration. Silicon steel laminations for stator and rotor cores employ high-permeability, low-hysteresis materials to curtail iron loss and heat buildup amid rotation. Every rotor undergoes precise dynamic balancing calibration to diminish operational vibration and acoustic emission. Such structural merits are accentuated in low-speed iterations; practitioners monitor operational conditions via real-time rotational velocity, and the calibrated 12 pole motor rpm reading of 495 revolutions per minute aligns impeccably with theoretical computation, precluding speed discrepancies that compromise the efficiency of coupled machinery. All terminal blocks bear distinct delta connection markings, facilitating field wiring, commissioning and periodic maintenance for electrical technicians. Weighing 3480 kilograms, the robust unit withstands rigorous operational environments within chemical complexes, pumping stations and metallurgical plants.

Regarding application compatibility and post-sale safeguards, the SIMO YL series boasts extensive market penetration throughout domestic and international industrial arenas. It functions as the premier driving hardware for vertical water pumps, oversized cooling blowers, industrial circulating water frameworks and agricultural hydraulic machinery. Relative to conventional universal motors, its vertical-oriented structural reinforcement extends service longevity by 20% under vertical installation scenarios, mitigating recurring bearing replacement and upkeep expenses. All finished units endure rigorous factory auditing, encompassing no-load trials, loaded temperature-rise assessments and insulation resistance verification, with exclusive serial codes enabling full lifecycle production traceability. Fabricated per standardized protocols at SIMO's intelligent manufacturing base in Xi'an, the motor delivers perennial stable operation under consistent power supply. For project stakeholders seeking steady low-speed constant torque, this lineup prevails, and the finalized configuration of 12 pole motor rpm guarantees uniform matching precision for bulk equipment assembly. Endowed with complete international certifications, stable parameter homogeneity and enduring robustness, SIMO YL vertical asynchronous motors furnish dependable, economical power backing to fulfill global heavy-industry vertical transmission requisites.
