Abstract
PURPOSE:To contrive to facilitate the attaching work of blades for the fan by a method wherein the blades for the fan are inserted into grooves provided on a rotor and are cast into the grooves for a conducting body of the rotor to form it while the bent part of the blade is burried into the groove of the rotor by aluminum or the like. CONSTITUTION:The blade 26 of the fan is inserted into the groove 22c provided on the rotor 22, thereafter, is cast into a groove 22b for the conducting body of the rotor with aluminum or the like to form the conducting body of the rotor, simultaneously, the fan blade 26 is secured to the rotor 22 by burrying the bent part 26a into the groove 22c with the aluminum or the like. Thus, the fan blade 26 is burried into and secured to the groove 22c provided on the rotor 22 simultaneously with the casting of the conducting body of the rotor without necessitating the calking work thereof, therefore, the work to attach the fan blade 26 to the rotor 22 of the motor may be facilitated remarkably.
