Product Introduction

The YE3 series ultra-high efficiency three-phase asynchronous motor is a totally enclosed, self-fan-cooled (TEFC), squirrel-cage three-phase induction motor manufactured using new materials, advanced processes, and optimized design. It represents a new generation of energy-saving motors.

The YE3 series motors cover frame sizes H80–355, with power ratings from 0.75 to 375 kW, and are available in 2-pole, 4-pole, and 6-pole versions.

The protection class of YE3 series motors is IP55, and the cooling method is IC411. Mounting dimensions comply with IEC standards. Rated voltage is 380 V or 400 V, with a rated frequency of 50 Hz. The allowable ambient temperature range is −15°C to +40°C, and the installation altitude should not exceed 1000 meters. Duty type is continuous operation (S1).

YE3 series ultra-high efficiency three-phase asynchronous motors feature high efficiency, high starting torque, low noise, and a more rational structure. With excellent cooling and heat dissipation performance, this series is designed as a general-purpose three-phase induction motor. It can be used to drive various general mechanical equipment such as compressors, fans, and pumps, and is also suitable for applications in petroleum, chemical, pharmaceutical, mining, and other industries (for special environmental conditions, please consult with the design engineers).

The efficiency values of this series meet or exceed the IE3 efficiency levels specified in IEC 60034-30 and the Grade 3 energy efficiency requirements of GB 18613-2020.

Model Description

The YE3 series ultra-high efficiency three-phase asynchronous motor is a new type of energy-saving motor developed using modern design techniques and optimized engineering.
