<p>In a rotor assembly process for assembling rotors (50) to a case main body (20) where stators (40) are fixed, lower portions (52A) of the rotor shafts (52) are fitted into two bearings (B1) fixed to the case main body (20) with two lower shafts (70) being fitted into inner circumferential surfaces (52x) of the rotor shafts (52). In a cover assembly process for assembling a rear cover (30) to the case main body (20), two bearings (B2) fixed to the rear cover (30) are fitted into upper portions (52B) of the rotor shafts (52) with the lower shafts (70) being fitted into the inner circumferential surfaces (52x) of the rotor shafts (52). Central axes of the rotor shafts (52) are prevented from inclining, and the rear cover (30) can be easily assembled to the case main body (20) without having to form large chamfers on the two bearings (B2) and the two rotor shafts (52).</p> |
