An induction motor is an electrical device that converts electrical energy into mechanical energy. It is most widely used for industrial applications due to its self-starting attribute. Slip ring induction motor is one of the types of 3-phase induction motor and is a wound rotor motor type. Because of various advantages like low initial current, high starting torque, and improved power factor, it is used in applications that require high torque, cranes, and elevators.
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.

Feature of Induction motors
YR slip ring induction motor has the advantages of high efficiency, strong overload capability, large starting torque, reliable structure and beautiful appearance. The enclosure protection grade is IP44, which has good protection performance, can be used in dusty environment, and is not flammable. General place for explosive or corrosive gases. In environments with relatively humid and slightly corrosive gases, it is also better than a protective structure.
The difference between these two motors is discussed below.
|Slip Ring Motor||Squirrel Cage Motor|
|It has a rotor of wound type||Its rotor is of squirrel cage type|
|Rotor has cylindrical core has parallel slots, in which each slot has a bar||Slots are not parallel to each other|
|Construction is complicated because of slip rings and brushes||Construction is simple|
|External resistance circuit is connected with a motor||No external resistance circuit as bars of the rotor is completely slotted|
|Starting torque is high||Torque is low|
|Efficiency is low||Efficiency is high|
The advantages are
High and excellent starting torque to support high inertia loads.
It has a low starting current due to external resistance
Can take full load current that is 6 to 7 times higher
The disadvantages are
Includes higher maintenance costs due to brushes and slip rings compared to squirrel cage motor
High copper loss
Low efficiency and low power factor
Expensive than 3 phase squirrel cage induction motor
Slip is defined as the difference between the flux speed and the rotor speed. For an induction motor to produce torque, at least some difference should be there between stator field speed and rotor speed. This difference is called ‘slip’. The Slip Ring” is an electromechanical device that aids in transmitting power and electrical signals from a stationary to a rotating component.
Slip rings are also known as rotary electrical interfaces, electric rotary joints, swivels, or collector rings. Sometimes, based on the application, the slip ring requires higher bandwidth to transmit data. Slip rings improve the efficiency and performance of a motor by improving system operation and eliminating wires that are dangling from motor joints.
