OEM YE3 Series High Efficiency Three Phase Motor

The YE3 Series High Efficiency Three-Phase Asynchronous Motor embodies our energy-saving design, engineered to exceed the IE3 premium efficiency benchmark and fully aligned with IEC/GB world standards.

1. Design & Build: Robust, Standardized, and Modular

Enclosed, Fan-Cooled Squirrel-Cage Construction

The YE3 employs a totally enclosed, fan-cooled (IC411) squirrel-cage design, ensuring efficient heat dissipation, dust resistance, and continuous operation—key to industrial reliability.

Protection & Insulation

Engineered with IP55 protection, the motor resists dust ingress and low-pressure water jets—suitable for damp manufacturing settings. Insulation is Class F, enabling higher temperature tolerance and long-term durability.

Mounting & Housing Flexibility

Accepting standard IEC installation dimensions, the motor supports popular configurations such as B3 (foot), B5/B35 (flange), and V1 variants, simplifying integration into various setups.

Power & Frame Range

The YE3 family spans 0.55 kW to 315 kW in various frames from H80 to H355, with options for 2-, 4-, or 6-pole configurations, catering to both compact and high-power applications.

Materials & Bearings

Smaller frames often feature aluminum motor bodies, while larger ones shift to cast-iron construction for enhanced robustness. Bearings vary: maintenance-free for compact units and oil-injectable, open bearings for heavier frames.

2. Performance & Efficiency:

IE3 Efficiency Compliance

By design, the YE3 meets or exceeds IE3 / IEC60034-30 Efficiency Class 3 and GB18613-2020 Grade 3, earning the High Efficiency title and delivering long-term energy savings.

Key Operational Traits

These motors deliver high starting torque, low noise, minimal vibration, outstanding thermal dissipation, structural optimization, and stable performance—good for demanding industrial environments.

Efficiency Benchmarks (Select Models)

For example, YE3-132S1-2 (5.5 kW) achieves about 89.2% efficiency, while the 280L frame achieves up to 95.8%, with power factors nearing 0.9—demonstrating real high-efficiency output in large frames.

3. Industrial Applications: Versatile & Ready

The YE3 is a general-purpose powerhouse: ideal for driving compressors, fans, pumps, conveyors, mixers, crushers, and more. Its design suits application in sectors like petrochemical, pharmaceutical, mining, food processing, agriculture, HVAC, metalworking, and firefighting systems.

Its reliability and efficiency make it especially suited for energy-conscious upgrades or new installations across industries.

4. Installation & Operation Conditions

Environmental Range

Designed for continuous S1 duty, these motors function reliably in ambient temperatures from –15 °C to +40 °C (some sources note up to +50 °C), at altitudes up to 1,000 m above sea level.

Cooling

The IC411 fan-cooling ensures consistent thermal management, even under heavy load.

5. Manufacturer's Value Proposition

From our factory's standpoint, the YE3 Series stands out by balancing:

These advantages translate into long lifespan, reduced maintenance, global compatibility, and environmental sustainability—appealing to OEMs and end-users alike.
