Publication number: 20240039434Abstract: A dual motor system includes a first motor providing a lower speed range and a second motor providing a higher speed range, wherein the motors are coaxially arranged and aligned on and drive a common shaft, and a motor control system controlling the speed of the first motor and engaging the second motor as needed. The first motor provides a lower two-thirds of a full speed range, and the second motor provides the upper one-third in the form of one or more discrete fixed speeds. The system may also include a flow control system for automatically controlling the speed of the motors for particular applications, such as flow control in a pool.Type: ApplicationFiled: October 9, 2023Publication date: February 1, 2024Applicant: Nidec Motor CorporationInventors: Eric Coupart, James D. Ellis, II, Pranesh Rao, John G. Schrader, Bret S. Clark

Patent number: 11784591Abstract: A dual motor system includes a first motor providing a lower speed range and a second motor providing a higher speed range, wherein the motors are coaxially arranged and aligned on and drive a common shaft, and a motor control system controlling the speed of the first motor and engaging the second motor as needed. The first motor is a variable speed motor providing a lower two-thirds of a full speed range, and the second motor is an induction motor providing the upper one-third in the form of one or more discrete fixed speeds. The system may include a transformer including a first winding tap which provides a first higher speed, and a second winding tap which provides a second higher speed. The system may also include a flow control system for automatically controlling the speed of the motors for particular applications, such as flow control in a pool.Type: GrantFiled: October 23, 2020Date of Patent: October 10, 2023Assignee: Nidec Motor CorporationInventors: Eric Coupart, James D.

Patent number: 8283824Abstract: A fluid deflecting baffle is provided for use on an electric motor to be used in an environment where liquid may otherwise pass through a vent opening in an endshield of the motor. The baffle is secureable to the endshield and extends in a partial covering relationship with the vent opening. The baffle includes a vent passage therethrough and has at least one liquid flow obstructing louver that extends across the vent opening to deflect liquid away from the vent passage while allowing venting air to flow through the vent passage. The louver includes a generally flat liquid deflection surface that is disposed at an oblique angle relative to the axis of the motor and at least partially faces a venting direction of incoming air and fluid.Type: GrantFiled: September 23, 2011Date of Patent: October 9, 2012Assignee: Nidec Motor CorporationInventors: Jose L. Vadillo, Raymond D. Heilman, John G. Schrader, James D. Ellis, II, Patrick M. Jones
