YE5 Most Efficient Motor Three Phase Asychronous 380V

Title:

YE5  Three Phase Asychronous  Motor

Brief Introduction

YE5-250M-6 W, a three-phase most efficient motor manufactured by Xi'an SIMO Motor Co., Ltd.-a reputable industrial motor specialist with a legacy of engineering reliability.

As a standout model in SIMO's ultra-efficient YE5 series, this unit (produced in November 2025, weight: 416kg) carries the CE mark, underscoring compliance with international quality standards, and is backed by SIMO's dedicated support (tel: 400 029 1177), rooted in strict manufacturing protocols (standard number: Q/XD.510.292).

Rated at 37KW and as a most efficient motor, it operates on a 380V/50Hz power supply, delivering a steady 990r/min rotational speed with a 70.8A rated current and 0.83 power factor (cosφ). Its defining strength lies in its 95.6% energy efficiency (EN.EFL class)-a figure that outperforms most conventional industrial motors (including older YE3/Y2 series models), translating to 10-15% lower annual energy costs for users while aligning with modern sustainability goals.

Built for non-stop S1 duty cycles, the YE5-250M-6 W thrives in harsh industrial environments. Its IP55 protection rating shields internal components from dust ingress and water splashes, while its 155℃ thermal class (F-class insulation) tolerates elevated operating temperatures-reducing winding damage risk versus motors with lower insulation grades. Paired with precision 6314/C3 bearings (for both drive and non-drive ends) and an IC411 self-fan cooling system, it maintains stable temperatures, minimizing mechanical wear and cutting maintenance frequency by up to 20% versus competing units.

Its IM B3 horizontal mounting design enables seamless compatibility with existing setups, allowing direct replacement of outdated motors without modifying infrastructure-a flexibility rare in brand-specific competitor models. This versatility makes it a go-to solution across applications: it delivers consistent torque for water pumps, sustains high-load cycles for air compressors, and supports heavy logistics via conveyors. It also performs reliably for fans, mixers, and general industrial machinery, eliminating the need for multiple specialized motors.

Merging SIMO's rigorous standards with industry-leading efficiency, durability, and adaptability, the YE5-250M-6 W is more than a most efficient motor-it's a cost-effective, low-downtime power core. For operations prioritizing long-term savings and multi-scenario utility, it outperforms one-dimensional competitor offerings.

Main Technical Parameters

Why choose Simo Brand YE5 series of Motor?

Ultimate Energy Efficiency for Drastic Cost Reduction

Boasting an ultra-high efficiency of 95.6% (complying with IE5 premium efficiency standards), this motor cuts power consumption by over 10% compared to conventional models. Tailored for 24/7 continuous industrial operation, it slashes annual electricity bills significantly, delivering substantial long-term savings for your business.

Industrial-Grade Protection for Stable Performance in Harsh Conditions

With an IP55 protection rating, it is fully dust-proof and resistant to low-pressure water jets, adapting seamlessly to outdoor, dusty, or humid working environments. The Class F insulation (155℃ heat resistance) operates with a safety margin under Class B temperature rise limits. Equipped with 6314/C3 bearings and the IC411 self-fan cooling system, it ensures consistent, trouble-free operation and minimizes failure risks.

Low Maintenance & High Reliability for Uninterrupted Production
