Motor Overview
The YE4 series (IP55) ultra-high efficiency three-phase asynchronous motors produced by Xi’an Taifu Simo Motor (Frame Numbers 80～355) (hereinafter referred to as “motor”) are low-voltage, fully enclosed, self-cooling, squirrel-cage type three-phase asynchronous motors with ultra-high efficiency, meeting the IE4 efficiency requirements of the latest version of the international standard IEC 60034-30 “Efficiency classification of single-speed three-phase cage induction motors.” The efficiency values fully meet the energy efficiency grade 1 requirements of the national standard GB18613 “Energy Efficiency Limit Values and Energy Efficiency Grades for Small and Medium-sized Three-phase Asynchronous Motors,” representing the highest standard efficiency globally. Efficiency is determined by the power loss analysis method of measuring input-output power (according to the provisions of 11.3 in GB/T 1032-2012).
The motor’s installation dimensions and power ratings comply with international IEC standards and are consistent with German DIN42673 standards. The motor’s protection level is IP55, cooling method is IC411, and it operates on a continuous duty cycle (S1). It adopts F-class insulation structure, but the entire series is evaluated according to B-class temperature rise; load noise evaluation is also required.
The motor’s rated voltage is 380V, rated frequency is 50Hz, and power range is 0.75 to 375kW, including 2-pole, 4-pole, and 6-pole motors. Motors with a power of 3kW or below use Y connection method, while others use Δ connection method.
Frame numbers H80～160 adopt a fully enclosed bearing structure, while frame numbers H180 and above use an open bearing structure with front and rear bearings equipped with non-stop refueling devices. The motor is equipped with anti-condensation drain holes. The standard motor wiring box exits from the top, but it can be modified for right-side or left-side exit according to user requirements. The junction box can be rotated 90° and 180° to facilitate different user wiring positions.
