Machine Tool Factory

From 2018 to 2022, Shenyang Machine Tool Factory ordered 60 sets of YE3 series, YVFE2 series and YB3 series motors produced by Milestone Motor.

YVFE2 series variable-frequency adjustable speed three-phase asynchronous motors are variable-frequency adjustable speed three-phase asynchronous motors powered by frequency converters. By changing the power frequency, the speed of the motor can be adjusted smoothly to achieve the purpose of energy saving and control automation.

YVFE2 series motors have high efficiency, wide speed regulation range, high accuracy, stable operation, convenient operation and maintenance, their installation dimensions meet the standards of the International Electrotechnical Commission (IEC), and their enclosure protection grade is IP55; The motor is equipped with external fan cooling fan; The motor rating is a continuous rating based on the continuous working system (S1); The rated voltage of motor is 380V; Rated frequency of Class F insulation is 50Hz; The motor can ensure constant torque operation and constant power operation (50Hz to 60Hz for 2-pole motors, 50Hz to 100Hz for 4-pole to 6-pole motors other than 355-4, and 50Hz to 75Hz for 355-4 motors) within the frequency range of 3Hz to 50Hz.

YE3 series ultra-high efficiency three-phase asynchronous motors comply with the GB/T28575 Technical Conditions for YE3 Series (IP55) Three phase Asynchronous Motors (Frame No. 80~355), and the efficiency indicators comply with the level 2 energy efficiency (energy conservation evaluation value) of GB18613 Minimum and Medium sized Three phase Asynchronous Motors Limited Values of Energy Efficiency and Energy Efficiency Grades. 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.

The rated voltage of this series motor is 380V, the rated frequency is 50Hz, the protection grade is IP55, the cooling mode is IC411, the self cooling of the fan adopts class F insulation, the full load temperature rise is assessed according to class B, and it can operate continuously in the environment with 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, 60Hz frequency, altitude higher than 1000m and other special requirements of ultra-high efficiency motors.
