Motor Introduction
YR series IP44 motor is a protected wound rotor three-phase asynchronous motor. The power level and installation size of the motor comply with IEC international standards. The enclosure protection class is IP44 and the cooling method is IC411. Class F insulation is used. Rated voltage is 380V, rated frequency is 50HZ, stator △ connection, rotor Y connection.
This series of motors can provide a large starting torque at a small starting current,and can adjust the speed within a certain range.
Suitable for use in non-flammable, explosive, corrosive gases and clean, natural locations.
Motor Advantages
High efficiency, high overload capacity, low noise, small vibration, reliable structure, beautiful appearance and so on. Especially suitable for export, and can be matched with the imported equipment and exchanged. This series is used to replace the products of JR, JR2, JR3 and other old series wound rotor motors. It is an ideal product for achieving energy saving and consumption reduction,improving the supporting Zhuji technology and operational reliability.
Field of application
Such as ball mills, fans, compressors, water pumps, crushers, cutting machine tools, transport machinery, winches, hoists, wire drawing machines, sugar presses, hoists and other original motor. In addition, it can also be used to drive large-inertia fans, coal mills, rolling mills, winches, shovels and other machinery.
