Latest Patents

Among his latest innovations is a cooling structure designed for rotary electric machines. This inventive cooling structure utilizes coolant to effectively cool the coil end portions that extend outward from each end surface of a stator core. The design includes a lead side cover member, which forms a first coolant chamber for the lead side coil end portion connected to a lead wire, and a non-lead side cover member that encompasses the opposite coil end portion, creating a second coolant chamber. A coolant communication path allows for fluid interchange between these chambers, ensuring optimal cooling performance.

Another significant patent involves an electric motor that features a rotor, stator, and protective covers. The construction of the stator coil, which is a pre-wound coil inserted into the stator core, showcases a no-lead-wire side coil end portion protruding radially inward. A secure coolant chamber, defined by the cover and a seal plate on the stator core’s inner side, is an essential aspect of this design, emphasizing the efficient cooling capabilities integral to the motor's operation.
