Latest Patents

Yamanaka holds a patent for a stator for an electric motor. This invention features insulating members formed on laminated iron cores divided for each pole-tooth unit. The windings are applied perpendicularly to the pole-tooth portions in a high-density alignment. By combining a predetermined number of laminated iron cores into a cylindrical configuration, Yamanaka's design constructs an integral structure stator with rigidity. This innovation allows for a conductor space factor of 70%, promoting high densification of the windings and saving space in the winding end portions. Additionally, the design prevents a reduction in motor efficiency due to joint portions and eliminates the need for integrally forming by resinous members, thus avoiding inter-winding short-circuiting. Welding may be replaced by adhesive bonding, and an annular member can be used to form an integral structure of the divided iron core lamination.
