Abstract: 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.

Abstract: A lamination for use in an electric machine stator includes a body having a generally circular outer periphery and a generally circular inner periphery, spaced from the outer periphery and a plurality of spaced apart teeth extending inwardly from the circular inner periphery. Each of said teeth define opposed inner edges thereof. The lamination includes a first pair of tips extending tangentially in opposed directions from the inner edge of one of said teeth and a second pair of tips extending tangentially in opposed directions from the inner edges of another one of said teeth. A tip of the first pair of tips and a tip of the second pair of tips define a first configuration having a first gap therebetween and defining a second configuration having a second gap therebetween. The first gap being substantially less than the second gap.

Abstract: A control system for a pump motor includes a first portion disposed outside a housing of the pump motor. The first portion may include a wireless communication interface and a processor. In some embodiments, the processor of the first portion is configured to control the wireless communication interface to receive a user input from a user device, and generate a control signal in response to receiving the user input. The control system also includes a second portion physically separate from the first portion and communicatively coupled to the first portion. The second portion may include a processor configured to receive the control signal from the first portion, and control the pump motor in response to receiving the control signal.
