YR2(IP44 IP54) ac motor

YR2 Series (IP54) motor is a closed wound rotor three-phase asynchronous motor is the latest design of replacement products. The power level and mounting dimensions conform to IEC international standards.
The series motor rotor can be changed by external resistor to obtain good starting performance (in smaller starting current, to provide a larger starting torque) and a small speed requirements. It is widely used in the squirrel cage rotor motors require more than the starting torque; insufficient grid capacity squirrel cage rotor motor starter, the starter and the starter more frequent and longer linked into electrical axis for synchronous drive and other occasions. Such as: metal cutting machine, crusher, ball mill, rubber machines, compressors. Sugar Mill. Rolling mill. Roberts, hoist, conveyor belts, etc. need to re-load starting of mechanical equipment.
This series motors with high efficiency, strong overload capacity, low noise, small vibration, reliable structure, beautiful appearance and other characteristics, especially for stand-alone or supporting exports, and with imported equipment supporting interchangeable.

Electrical parameters
1 Rated voltage 380V, rated frequency 50HZ. According to user needs can also be made 400V, 415V, 420V 440V 690V 1140V and 60HZ etc.
2 Delta connection rotor stator is Y connection
3 motor with 155 (F) class insulation; cooling method is IC411; continuous duty (S1).
4 motor housing protection class IP54. Including H355-450 collector ring protection class IP23.H160-450 rotor all with separate top outlet connection more secure, reliable, and convenient.
