Abstract: Segmented stator assemblies having a plurality of stator segments and a plurality of end caps are disclosed. According to one example embodiment, a segmented stator assembly includes a plurality of stator segments and a plurality of end caps. Each stator segment has a yoke portion and a tooth portion extending from the yoke portion. Each end cap is positioned over one of the stator segments. Each end cap includes a body portion positioned at least partially over the yoke portion of its associated stator segment. At least one of the body portions includes at least a first post that cooperates with a post of an adjacent end cap to define a first wire management tie-down. The stator assembly further includes a stator wire coupled to the first wire management tie-down. Stator assemblies and end caps having other wire management and routing features are also disclosed.

Abstract: A blower motor assembly having a variable speed motor that is suitable for direct, drop-in replacement in a residential HVAC (heating, ventilation, and air conditioning) system that employs a PSC motor. The blower motor assembly includes at least a neutral input and two hot AC line connections, one for connection to the heating power source and the other to the cooling power source. A sensing circuit senses which of the inputs is energized by sensing either voltage or current on the inputs. The sensing circuit delivers a corresponding signal to a motor controller to control the speed of the variable speed motor. The blower motor assembly may also be equipped with additional hot AC inputs, more than one neutral line, and several sensing circuits for sensing current or voltage in the hot inputs and/or the neutral lines for controlling various aspects of the variable speed motor.

Abstract: A motor programming tool is disclosed for associating with a connection block of a motor and sending signals to a programmable controller of the motor, where the connection block includes a plurality of terminals coupled to the controller. The programming tool includes a tool body with an interface generally corresponding with the connection block of the motor, wiring operable to carry the signals, and a plurality of terminal connecting assemblies to associate with the motor terminals. The tool body includes a shiftable locking mechanism operable to selectively secure the tool body relative to the electrical connection block of the motor.

Abstract: A rotor for an outer rotor-type motor is provided. The rotor includes a metallic coupler and a polymeric frame molded over at least part of the metallic coupler.
