<p>Through-holes (11, 12, 13,...) are formed at predetermined positions in a stator core (1), reinforcing bars (51, 52, 53,...) are each inserted into holes in fixing structures (81, 82, 83,...) by welding to the stator core, the core is sandwiched from both sides between a front bracket (31) and a rear bracket (32), front and rear threaded bolts (91, 92, 93,...), (61, 62, 63,...) passing through the front and rear brackets, respectively, are provided at either end of the reinforcing bars and engage with threads, thereby fixing together the stator core, the front bracket and the rear bracket. The heat dissipating action of the stator core can be improved by this structure, and the size of the motor reduced. </p> |
