Product Overview:YVF3 series frequency conversion speed control three-phase asynchronous motor is a special three-phase asynchronous motor with frequency conversion speed control device as the power supply, and the system composed of frequency conversion device can realize the infinitely variable speed control, and achieve the purpose of energy saving and control automation.The YVF3 series motors adopt the squirrel-cage structure, which is reliable in operation and convenient in maintenance. The motors are equipped with independent axial fans to ensure that the motors have a better cooling effect at different speeds. The main performance of this series of motors conforms to the relevant provisions of JB/T11710-2013 and complies with the provisions of the IEC standard.YVF3 series motors can be applied to a variety of transmission devices that require speed regulation, and they are widely used in light industry, textile, chemical industry, metallurgy, lifting, machine tools and other industries.Together with the high-precision sensors, they can realize high-precision closed-loop control.
