Product Description

        YVF series variable frequency speed regulation high voltage three-phase asynchronous motors (frame size 315~630) (hereinafter referred to as motors) are new products developed by our company according to market demand. When used with a frequency converter, they can achieve smooth stepless speed regulation in a wide range, of which the frequency range of 5-50Hz is constant torque speed regulation, and the frequency range of 50-100Hz is constant power speed regulation. It is an ideal drive product to meet the needs of speed regulation equipment.

        This series of motors are made of carefully selected materials and well-made. They have the characteristics of wide speed regulation range, high efficiency, low noise, low vibration, safe and reliable operation, convenient use and maintenance, energy saving and environmental protection.

Applications

         This series of motors has the characteristics of lower center height, greater power, higher efficiency, lower noise, safe and reliable operation, and convenient use and maintenance. It is suitable for driving various ventilators, compressors, water pumps, transportation machinery, general machinery and other mechanical equipment with constant torque and quadratic torque characteristics for general purposes, and is used as the original power in various working conditions such as mining, steel, machinery, petroleum, chemical industry, power station, etc.

        When the working speed is adjusted below the rated speed, the energy saving effect is very obvious. Whether indoors or outdoors, in plateau climate or humid and hot climate, this series of high-voltage three-phase asynchronous motors can always provide outstanding driving force and has won the trust and praise of users.
