    Abstract: A P.M. d.c. motor which may utilize "brushless" commutation. The motor includes a stator assembly with a plurality of upstanding discrete spaced-apart core components formed in a circular locus generally parallel with the motor axis. Each core component includes a relatively lengthy winding association region and extending therefrom a pole piece region providing a flux interaction surface. A field winding mounted upon a bobbin is positioned over the core component at the winding association region and when excited, generates electromagnetic flux at the flux interaction surface. A permanent magnet component is carried by a rotor such that its interaction surface is adjacent to that at the pole piece region, and is spaced therefrom to define a flux working gap at a desirably lengthy working gap radius from the motor axis.

    Abstract: Systems and methods for controlling a draft inducer for use with a furnace. The draft inducer includes a motor for driving a fan for inducing a draft in the furnace that causes a pressure drop across the heat exchanger of the furnace. A memory stores information including a table of predefined speed/torque values for defining a set of speed/torque curves for operating the motor. A pressure switch provides a pressure signal representative of a reference pressure across the heat exchanger and a processor determines the speed and torque of the motor when the pressure drop corresponds to the reference pressure. In response to the determined motor speed and motor torque, the processor retrieves a parameter defining at least one delta value from the memory. The processor adapts the predefined speed/torque values as a function of the delta value thereby to define the speed/torque curves corresponding to a desired pressure drop. A control circuit generates a motor control signal in response to the defined speed/torque curves to cause the motor to operate as a function of the determined motor speed and motor torque for controlling the draft induced in the combustion chamber.

    Abstract: Systems and methods for controlling a draft inducer for use with a furnace. The draft inducer includes a fan for moving combustion chamber gases for inducing a draft in the furnace combustion chamber that causes a pressure drop across a heat exchanger. The density of the gases flowing across the heat exchanger and the fan differs from a first operating state of the furnace to a second operating state of the furnace. A motor drives the fan in response to a motor control signal so that different motor speeds result as a function of the density of the gases flowing across the fan. A control circuit generates the motor control signal as a function of a first set of speed/torque curves until a speed signal indicates that the motor has reached a predetermined speed. After the speed signal indicates that the motor has reached the predetermined speed, the control circuit generates the motor control signal as a function of a second set of speed/torque curves. Thus, the motor will operate in accordance with the first speed/torque curves when the furnace is in the first operating state and in accordance with the second speed/torque curves when the furnace is in the second operating state.
