Brief Introduction
YR series IP44 motor is also called 3 phase slip ring motor. It is a wound rotor three-phase asynchronous motor with slip ring. The power rate and installation dimensions are accord with IEC international standards. The protection class is IP44/IP54 and the cooling method is IC411. Insulation Class is F. Default ated voltage is 380V, rated frequency is 50HZ, △ connection for stator and Y connection for rotor.
This series of motors can provide a large starting torque at a small starting current,and can adjust the speed within a certain range.

YR Motor Introduction
YR series 3 phase slip ring motor is a wound rotor three-phase asynchronous motor with slip ring. The power rate and installation dimensions are accord with IEC international standards. The protection class is IP44/IP54 and the cooling method is IC411. Insulation Class is F. Default ated voltage is 380V, rated frequency is 50HZ, △ connection for stator and Y connection for rotor.
This series of motors can provide a large starting torque at a small starting current,and can adjust the speed within a certain range.
It is suitable for work places that do not contain flammable, explosive and corrosive gases and are relatively clean.
Advantages
The 3 phase slip ring motor has the outstanding advantages of high efficiency, high overload capacity, low noise, small vibration, reliable structure, beautiful outlook 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.
Operation condition
Ambient temperature is -15℃~+40℃; Altitude ≤1KM; and monthly average air humidity ≤90% (If temperature is 25℃). Suitable for use in non-flammable, explosive, corrosive gases and clean, natural locations.
Application
This series of 3 phase slip ring motor is commonly used to drive 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.
