Ykk Series IP23 IP54 IP55 High Voltage Ac Motor induction motor For Rolling steel

Product overview

Y. The power grade, electrical performance, installation dimension and tolerance of YKS and YKK series medium-sized high-voltage three-phase asynchronous motors (frame No. 355-630) comply with the national standard gb755 rotating motor rating and performance, the International Electrotechnical Commission Standard iec34-1 rotating motor rating and performance, and the machinery industry standards jb/t7593,jb/t10315.1, jb/t10315.2, etc

According to gb4942.1 and iec34-5, the enclosure protection grade of this series of motors includes IP23, ipw24, IP44 and IP54 respectively IP23 motor can be made into IP44 (pipe ventilation) according to user requirements If users need other protection grades, they can be supplied separately

The cooling methods of this series of motors are ic01, ic611 and ic81w according to gb/t1993 and iec34-6 cooling methods for rotating electrical machines If users need other cooling methods, they can be supplied separately

The structure and installation type of this series of motors is IMB3 (horizontal with feet), which conforms to gb997 and iec34-7 < motor structure and installation type code >

1, Organization description

The motor base is welded by steel plate and adopts the overall square box structure, which has the characteristics of light weight and strong rigidity

The stator adopts the external press mounting structure, the stator winding adopts class F insulation, and the ends are firmly bound. The whole stator adopts the vacuum pressure impregnation solvent-free paint (VPI) process, so that the stator becomes a solid whole with good electrical performance and moisture-proof performance

There are two types of rotors: cast aluminum and copper strip. The cast aluminum rotor is cast from pure aluminum. The copper strip rotor is wedged in the groove by copper strip, and the copper strip and the end

The ring adopts reliable welding process

The motor bearing can be rolling bearing or sliding bearing, and the bearing protection grade shall be designed according to IP54 If it is a rolling bearing, it is lubricated with grease and equipped with oiling and oil drainage devices, which can be refueled without stopping the machine In case of sliding bearing, the oil supply system is generally provided by the user, and the efficiency of the motor is slightly lower than that in the technical data sheet according to relevant standards The main outlet box is designed according to the German DIN standard, and the protection grade is IP54. It is generally installed on the right side of the motor (viewed from the shaft extension end) According to the user's requirements, it can also be installed on the left. The outlet hole of the occurrence box can be switched in four directions: up, down, left and right There is a separate grounding device in the main outlet box

The motor is generally single shaft extension, and the shaft extension key is flat key, which can also be made into double shaft extension as required by the user

If users need, they can install stator winding and bearing temperature measuring elements, as well as moisture-proof space heaters for shutdown
