Panzhihua Smelter ordered 50 sets of Y3-355-450 series motors and YKK series in March 2019, and another 20 sets of YB3 series motors and 15sets of YE4 series motors in May 2021.

Y3-355-450 is a fully enclosed low-voltage differential high-power three-phase asynchronous motor. The rated voltages of this series of motors are 380V and 660V (see the voltage column in the performance data for specific models and voltages). The rated frequency of 50HZ can also be made into low-voltage high-power motors with other voltages and frequencies according to customer requirements. The protection grade is IP55, S1 continuous working system, and the cooling mode is C411. The base adopts a heat dissipation rib structure, made of cast iron; The bearing can realize non-stop oil injection and is equipped with a waste oil storage device in the bearing chamber; Two independent cooling air paths take away the heat of the motor and reduce the temperature rise of the motor; All adopt high-quality cold-rolled silicon steel sheet; The stator winding is Class H insulated enamelled wire; Vacuum impregnation ensures the reliability of insulation structure.

YB3 series Flameproof three-phase asynchronous motor is a new generation based on YB2 motor. It is a highly efficient motor popularized by the country. Features of high efficiency, low noise, small vibration, high locked rotor torque, reliable operation, beautiful appearance, etc. It is one of the important electrical products used in the petroleum, chemical and coal industries.

YB3 series flame-proof three-phase asynchronous motor has rated voltages of 380V, 660V, 380/660V, 660/1140V, rated frequency of 50Hz, protection grade of IP55, cooling method of IC411, Class F insulation, and full load temperature rise is assessed according to Class B.

YE4 series three-phase asynchronous motors comply with JB/T 13299-2017 Technical Conditions for YE4 Series (IP55) Three phase Asynchronous Motors (base number 80 〜 450), and their efficiency indicators are consistent with those in IEC60034 (IE4). This series of motors are high efficiency, energy saving, environment-friendly motors with low operating cost, low vibration, low noise, high reliability, and are suitable for driving various mechanical equipment without special requirements.

This series of motors has a rated voltage of 380V, a rated frequency of 50Hz, a protection grade of IP55, a cooling mode of IC411, Class F insulation, and a full load temperature rise of B, which can operate continuously at an altitude of no more than 1000m and a temperature of - 15 ℃~40 ℃. Our company can also design and manufacture motors of various voltages, frequencies and installation methods according to user requirements; Such as 220V, 400V, 415V, 440V, 660V voltage, 60H frequency, altitude higher than 1000m and other special requirements of ultra-high efficiency motors.
