PURPOSE:To enable to freely obtain a heat sink surface of a servo motor by alternately laminating stator laminated core piece layers of different outer dimeters and forming the heat sink surface area with the laminated core pieces themselves. CONSTITUTION:The motor section 1 of a servo motor is formed of two types of laminated stator cores 2, 3, and interposed between brackets 4 and 5. The core 2 is formed by laminating core pieces 6, and the core 3 is formed by laminating core pieces 7 of different outer diameters from that of the pieces 6. Thus, the core pieces of the different outer diameters are alternately laminated to form a stator core, thereby freely obtaining desired heat sink area and eliminating the necessity of a special frame. |
