Motor manufacturing is an important part of the whole machine manufacturing industry. In addition to the structural parts similar to the general machine, the motor has special conductive, magnetically conductive and insulating parts. Therefore, in the process of motor manufacturing, in addition to In addition to forging, casting, welding, metalworking and assembly, which are common in mechanical manufacturing, there are also processes unique to motor manufacturing, such as core punching and press fitting, commutator manufacturing, and winding manufacturing (winding). , forming, insulation, welt, dipping and drying).

In the motor manufacturing industry, in order to complete these special processes, in addition to metal cutting machine tools, there are also a large number of non-standard equipment (special equipment), such as iron core painting and drying (or oxidation treatment of iron core tablets) Special equipment used; aluminum melting furnace, preheating furnace and die casting machine (or centrifugal aluminum casting machine) for rotor casting aluminum, rotor copper strip (rat dragon structure) medium frequency welding machine; explosion-proof motor housing (ie cavity) Pressure test equipment; winding machine, bulging machine, package insulation machine, impregnation, drying equipment, etc. used in winding manufacturing, the manufacturing quality of these equipments and the working quality of the operation process on the performance of the motor and the reliability of the work Has a big impact.
