Schultz Chris Swenski Harry J. Walters Alan W. Yeadon William H. Yeadon 3.1 MOTOR MANUFACTURING PROCESS FLOW The basic manufacturing processes for electric ac and dc motors are shown in this section. Within each process there are significant variables each depending upon the manufacturing equipment size and variety of the parts electrical efficiency requirements and economics. Each one of these process variables is described in the following text. 3.1.1 AC Motor Manufacturing Process Flow Figure 3.1 illustrates a basic ac motor manufacturing process flow. The first step is producing laminations. These laminations are separated into rotors and stators. The stator laminations shown in Fig. 3.2 are then stacked into a core and copper and or aluminum wire is wound into the core producing a wound stator core. An outer housing of some type is produced and that is then wrapped around the wound stator core making a wound stator assembly. The wound stator assembly is then sent to motor assembly. Sections 3.1 to 3.9 contributed by Karl H. Schultz Schultz Associates except as noted. 3.1 3.2 CHAPTER THREE FIGURE 3.1 Ac motor manufacturing process flow. The rotor laminations in Fig. 3.3 are also stacked and then aluminum die cast into a rotor casting shown in Fig. 3.4. A shaft is then produced and this is assembled into the rotor making it a rotor assembly shown in Fig. 3.5.The rotor assembly is sent to motor assembly. Two end frames are produced and sent to motor assembly. At the final operation the wound stator assembly rotor assembly two end frames and miscellaneous parts are assembled into a complete motor. The motor is then tested painted and packed for shipment. FIGURE 3.2 Stator laminations. MECHANICS .
