What should I pay attention to when using the motor housing?


Dalian motor shell shall first remove the external wiring of the motor and make marks. For example, for asynchronous motor, the marks corresponding to the three-phase power line shall be made. For DC motor, the marks corresponding to the external wiring such as shunt winding and armature winding shall be made respectively. Then loosen the foot screws to separate the motor from the transmission machinery. The special eccentric rotary mould for front and rear position is installed on the fixed workbench. When the mould is turned to the front position (i.e. adding station), the workpiece is in the processing state, and when it is turned to the rear position, the workpiece is in the clamping and disassembly state. Put a steel pipe on one end of the shaft. In order to prevent the steel pipe from scratching the journal, the steel pipe can be lined with a layer of thick cardboard to continue to move the rotor out gradually. When the center of gravity of the rotor has moved outside the stator, a support is placed under the rotor shaft end, and the steel wire rope is put in the middle of the rotor to pull out all the rotors. PBT has weak hygroscopic properties. Generally, the shrinkage of materials is between 1.5% and 2.8%. The shrinkage of the material containing 30% glass additive is between 0.3% and 1.6%. The melting point (225%c) and high temperature deformation temperature are lower than those of pet. Vicat softening temperature is about 170C. The glass transition temperature is between 22c and 43c.


The stator coil is the easiest to be damaged. It has strict requirements for winding, embedding, connection, insulation and inspection. Mold is an important process equipment for modern industrial production. Mold industry is the basic industry of the national economy and a high-tech industry, known as the "mother of industry". Using die forming method to process parts can improve production efficiency, ensure part quality, reduce material consumption and reduce production cost. Considering that the force on the motor shell is relatively single and balanced, and good seismic resistance is required, HT200 is selected as the blank material and machine sand casting is adopted. Milling outer cylindrical surface, base surface and 1140.4mm inner surface. X6040 vertical milling machine is selected as the machine tool. The main motion focuses on the space flexibility of the machine tool. The CNC device is used to control the main transmission system and the feed servo system. The milling and drilling double process processing is completed continuously in one clamping, and the process flexible conversion is completed under the control of the PLC system and the hydraulic system to ensure that the auxiliary working hours are shortened.


Another feature of motor manufacturing is that there are many varieties and specifications; The capacity, voltage, speed and geometric dimension of the motor vary widely, and its uses, installation methods, cooling methods and protection forms are diverse. Therefore, the manufacturing process is also different and each has its own characteristics. The motor is allowed to be driven by coupling, spur gear and belt pulley, but belt drive is not suitable for 2-pole motor above 4kw and 4-pole motor above 30kW. If the small pulley is selected, the transmission range of the V-belt can be expanded. The fan end of the double shaft extension motor can only be driven by the coupling. Clean the internal sundries and dust, and fill with lubricating oil; It is better to use a 500 volt megger to measure the insulation resistance of the winding, which shall not be less than 0.5 megohm under normal conditions. This material is easily hydrolyzed at high temperature, so the drying treatment before processing is very important.
