The motor rotor of the part 3 6 g is embedded in the part 3 6 d. To engage the engaging protrusions 4 7 formed on the engaging pieces 4 7 c of the engaging clutch mechanism 4 7 (please read the precautions on the back before installing-this page). Standards are applicable to China National Standard (CNS) A4 specifications (210 X 297 mm) -20- 498122 A7 ___ One B7 V. Invention Description (18) (Please read the precautions on the back before IPk page) 5 4 d is related to The mounting hub 5 4 c is integrally formed on the mounting hub 5 4 c by resin molding. The mounting (use) hub 5 4 c is formed in the same size as the induction motor rotor 4 5 and can be mounted on the motor rotor embedded portion 3 6 d. The inner end side of the clamping end portion exposes the rotor core. 5 4 a, and embed the metal ring 5 4 e on the clamping end of the outer end side. Furthermore, the hub 5 4 c of the rotor can be formed into a short size by using a dedicated inner input shaft insertion shaft portion that is formed into a short size by using a motor rotor embedded portion. The permanent magnet magnetic pole 5 4 b is formed to protrude outside the stator winding 5 2 b, and a magnetic pole detection element 55 is set to oppose the rotation track of the protrusion, so as to detect the rotation position of the rotor 5 4 . The magnetic pole detection element 55 will be mounted on the cover (body) 48.

This paper size applies to Chinese National Standard (CNS) A4 (210 X 297 mm) -21-498122 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economy 4 3 and the inner input shaft portion 3 6 g are used to selectively install induction motors or brushless motors, it is necessary to consider the dimensions of the external shape and fitting part of the stator and rotor. In order to obtain the same output shape, the induction motor is generally larger. For this reason, the stator ^ 4 and rotor 45 of the induction motor need to be reviewed. The driving device 6 is composed of a planetary reduction gear mechanism, a meshing clutch mechanism, and a motor, which are arranged concentrically in series in a vertical direction with the driving rotation (rotation) shaft system 3 4 as the axis. The downward protruding amount of the mounting surface of the bottom surface of the outer groove 5 is within 16 mm. The driving device 6 is supported by the upper end of the driving rotating shaft system 3 4 by forming a washing and dewatering tank 2 and the stirring blade 4. Therefore, it is necessary to support the ball bearings 3 3 a, 3 3 b of the driving rotating shaft system 3 4. It is necessary to set as large a gap as possible. Therefore, the reduction gear housings 3 2 a, 3 2 b ′ to be provided with the ball bearings 3 3 a, 3 3 b will have an axial dimension equivalent to the axial distance of the ball bearings 3 3 a, 3 3 b. As a result of these size allocations, the size of the motor shaft direction, including the engaging clutch mechanism, will be about 90 mm. In order to maintain the output characteristics (about 250 W) of the induction motor, while reducing the size in the axial direction, the diameter of the stator 4 4 and the rotor 45 may be increased. However, when the cores 44a and 45a of the stator 4 4 and the rotor 45 are laminated by punching through the iron plate, the large-diameter cores 44a and 45a become expensive. Therefore, in this embodiment, the stator winding of the induction motor will be used. -------------- (Please read the notice on the back of tt. And then this page)
