2. Structure
The motor adopts a box structure. The base is welded by steel plate, which is light in weight and good in rigidity. A protective top cover is installed on the top of the machine base, which is convenient for disassembly and assembly, and is convenient for maintenance and repair of the motor.
The stator adopts an external press-fit structure. The stator winding is made of F-class insulating materials, and the ends are reliably fixed and tied. During the manufacturing process, it has undergone multiple turn-to-turn pulse voltage tests and ground pressure tests, and adopts German advanced vacuum pressure impregnation solvent-free paint equipment and technology (VPI) processing. Therefore, the motor has excellent and reliable insulation performance, good mechanical strength and strong moisture resistance.
The wound rotor adopts Class F insulation material.
There are two types of bearings, rolling bearings and sliding bearings, depending on the power and speed of the motor. The YR series is a basic series, and the protection level is IP23. YRQF series, (IPW24), YRKS series (IP44 or IP54) can also be derived according to order requirements.
The main junction box is generally installed on the right side of the motor (viewed from the shaft extension), and can also be installed on the left side of the motor according to order requirements. There is a separate ground terminal in the main junction box.
Three, use
Electric motors can be used to drive various general machinery such as compressors, water pumps, crushers, cutting machine tools, transportation machinery and other mechanical equipment, and are used as prime movers in various industrial and mining enterprises such as mining, machinery industry, petrochemical industry, and generators. Motors used to drive blowers, coal mills, rolling mills, and hoists should indicate their purpose and technical requirements when ordering, and adopt a special design to ensure reliable operation.
