Slip Ring Induction Motor

Slip Ring Induction Motor

Product Description

YR series (IP44) slip ring induction motor is a general-purpose wound rotor three-phase asynchronous motor. It is the latest design and updated product. Its installation size and power level are in line with the International Electrotechnical Commission (IEC) rotating motor standard, installation size and power level. The correspondence between the two is consistent with the West German DIN42679 standard. 
YR (IP44) slip ring induction motor can provide large starting torque at a small starting current and can adjust speed within a certain range 
YR (IP44) winding slip ring motor has a protective degree of IP44, which has good protection performance and can be used in dusty environments and in general places without flammable, explosive or corrosive gases. In environments with relatively humid and slightly corrosive gases, it is also better than a protective structure.

YR slip ring induction motor has the advantages of high efficiency, strong overload capability, large starting torque, reliable structure and beautiful appearance. In particular, the basic structural components such as the base are common to the Y (IP44) basic series of motors, and the parameters of the stator and rotor are relatively uniform, which brings convenience to the user. Anyone who has selected the JR series motor can use the YR series (IP44) motor instead.

YR series (IP44) slip ring induction motor is a general-purpose wound rotor three-phase asynchronous motor. Its power level and installation dimensions are in accordance with IEC standards. The protection grade of YR winding slip ring motor is IP44, which further improves the protection level. Make it more suitable for the use of mechanical equipment in special working conditions. It is widely used in the following situations:

(1) requires a larger starting torque than a squirrel-cage rotor motor;

(2) The capacity of the feeder line is insufficient to start the squirrel-cage rotor motor;

(3) A small range of speed regulation is required;

(4) Synchronized transmission of the "electric shaft". Such as compressors, sugar mills, textile machines, winches, wire drawing machines, conveyors and other machinery.

YR series (IP44) slip ring induction motor has the advantages of high efficiency, energy saving, low noise, low vibration, safe and reliable operation, convenient installation and maintenance. It can be used for various motors used in general purposes, such as ball mills, fans, compressors, water pumps, crushers, cutting machines, transportation machinery and other original motors. In addition, it can also be used to drive large torque inertia fans, coal mills, rolling mills, winches, electric shovel and other machinery, especially for mechanical equipment under special working conditions with high requirements on motor protection.

Product characteristics

YR slip-ring induction motor has the advantages of high efficiency, strong overload capacity, large starting torque, reliable structure and beautiful appearance. The enclosure protection class is IP44, with good protection performance, can be used in dusty environment, and non-flammable. A general place for explosive or corrosive gases. It is also better than the protective structure in environments with relatively wet and corrosive gases.
