YRKK series (H355~1120) 6KV, 10KV high-voltage three-phase
asynchronous motors are wound rotor asynchronous motors. The
protection level of this series of motors is IP44 or IP54, and the
cooling method is IC611, IC616, IC666 (see GB/T1993).
This series of motors has the advantages of high efficiency, energy
saving, low noise, low vibration, light weight, reliable
performance, convenient installation and maintenance, etc.
The YRKK high-voltage motor stator adopts an external press-fitting
structure, and the stator winding is made of F-class insulating
material, and the ends are reliably fixed and bound. During the
manufacturing process, it has undergone many inter-turn pulse
voltage tests and ground withstand voltage tests, and adopts German
advanced technology. The vacuum pressure impregnation solvent-free
paint equipment and process (VPI) process. Therefore, the motor has
excellent and reliable insulation performance, good mechanical
strength and strong moisture resistance.
YRKK high-voltage motor winding rotor adopts F-class insulation
material. There are two types of bearings: rolling bearings and
sliding bearings, depending on the power and speed of the motor. YR
series is the basic series, and the protection level is IP54. YRQF
series (IPW24) and YRKS series (IP44 or IP54) can also be derived
according to the ordering requirements.
The main junction box is generally installed on the right side of
the motor (viewed from the shaft extension end), and can also be
installed on the left side of the motor according to the ordering
requirements. There is a separate ground terminal in the main
junction box.
YRKK high-voltage motors can be used to drive various general
machinery such as compressors, water pumps, crushers, cutting
machine tools, transportation machinery and other mechanical
equipment, as prime movers in mining, machinery industry,
petrochemical industry, power plants and other industrial and
mining enterprises use. Motors used to drive blowers, coal mills,
rolling mills, and hoists should indicate their use and technical
requirements when ordering, and adopt special designs to ensure
reliable operation.
