Patent number: 11075552Abstract: A motor is cooled with a coolant. The motor includes a rotor rotatable about an axis, a stator including a stator core and windings wound about the stator core, a housing enclosing at least a portion of the stator, and a resiliently deflectable spray ring extending circumferentially relative to the axis. The spray ring defines at least one orifice configured to direct coolant on the stator. The spray ring presents first and second arcuately spaced apart ends defining a gap therebetween.Type: GrantFiled: September 24, 2019Date of Patent: July 27, 2021Assignee: Nidec Motor CorporationInventors: Raymond D.

Patent number: 9917486Abstract: An electric motor assembly including a stator having a stator core and windings around the stator core is disclosed. The stator core has opposing ends and an outer surface extending between the opposing ends. The electric motor assembly also includes a housing having an inner surface enclosing at least a portion of the stator, and at least one fluid passage between the outer surface of the stator core and the inner surface of the housing. The fluid passage permits a coolant in the fluid passage to contact one or more portions of the outer surface of the stator core to remove heat from the stator core during operation of the electric motor assembly. Additional motor assemblies including stator and/or rotor cooling features are disclosed.Type: GrantFiled: February 23, 2015Date of Patent: March 13, 2018Assignee: Nidec Motor CorporationInventors: Thomas E. Kirkley, Jr., Lawrence J. Wittman, Andrew F. Poag, Steven P. Randall
