US Classification:

31015608, 310216114, 29596

Abstract:

An electric machine is described. The electric machine includes a rotor comprising a rotor disk and a plurality of permanent magnets magnetically coupled to the rotor disk. The plurality of permanent magnets include a substantially flat profile and are aligned in a substantially planar array. The electric machine also includes a stator comprising a solid stator core and a plurality of coils each wound around a coil insulating member. The stator core includes a plurality of stator teeth extending substantially parallel to an axis of rotation of the rotor.

Abstract:

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.
