Patent number: 11873820Abstract: A blower has a blower housing of clamshell construction, including two housing members having a scroll back wall molded with radial draft, an impeller and a motor within the housing, and a static tap connected to the housing. The impeller has a backplate with a backplate back surface region of substantially the same radially converging shape as that of a front surface region of the scroll back wall formed by the radial draft, providing a substantially uniform axial gap between the backplate back surface region and the scroll back wall. The impeller has a ring connected by a skirt to the back plate to define a stepped area behind the ring. The impeller includes impeller blades extending forwardly from the impeller backplate and the ring and back fins extending rearwardly from the ring. The blower has a scroll width of about twice an impeller exhaust width.Type: GrantFiled: November 17, 2022Date of Patent: January 16, 2024Assignee: Regal Beloit America, Inc.Inventors: Steven W.

Patent number: 11603851Abstract: A draft inducer blower assembly includes a blower having a fan, a dilution air intake passage, an exhaust gas intake passage, and a discharge passage. The blower is configured to operatively connect to a heater system in a manner to facilitate flow of combustion air into a combustion chamber and to draw dilution air into the blower and to mix the dilution air with the exhaust gases and to facilitate flow of the mixed air and exhaust gases through the vent. The dilution air intake passage is positionable in at least a low flow configuration and a high flow configuration. The dilution air intake passage is more restrictive of intake of dilution air in the low flow configuration than in the high flow configuration.Type: GrantFiled: May 28, 2021Date of Patent: March 14, 2023Assignee: REGAL BELOIT AMERICA, INC.Inventor: Steven W.

Patent number: 11486576Abstract: A motor controller for a burner system includes an inverter that supplies current to a motor that rotates a draft inducer fan. A processor is coupled to the inverter and receives a signal from a system controller, and in response instructs the inverter to supply a first current, during a first period, to the motor to rotate the fan to produce a first mass flow through the burner system, the first mass flow having a first mass flow rate greater than a threshold to actuate a vacuum switch. The processor then instructs the inverter to supply a second current, during a second period starting at an expiration of the first period, to the motor to rotate the fan to produce a second mass flow through the burner system, the second mass flow having a target mass flow rate for normal operation of the burner.Type: GrantFiled: August 23, 2019Date of Patent: November 1, 2022Assignee: Regal Beloit America, Inc.Inventors: Steven W Post, Michael K.

Patent number: 11136992Abstract: An air handler blower assembly includes a blower housing containing a centrifugal fan and a motor mounted on the blower housing and connected to the fan. The blower housing has opposite first and second air inlet openings that are coaxial with the fan, and the first inlet opening is larger than the second inlet opening. The motor is mounted on the blower housing with the motor extending axially through the first inlet opening into the blower housing and into the interior of the fan. The positioning of the motor inside the blower housing and inside the fan reduces the overall axial dimension of the blower assembly. The larger first air inlet opening reduces the losses associated with placing the motor in the first air inlet opening while keeping the second air inlet opening at a smaller size than the first air inlet opening avoids creating buffeting noise and a power/efficiency loss from occurring.Type: GrantFiled: August 5, 2010Date of Patent: October 5, 2021Assignee: REGAL BELOIT AMERICA, INC.Inventor: Steven W. Post
