Abstract: A substantial saving of material cost and weight is obtained in an induction motor by a rotor including two sets of differently punched laminations. The laminations in one of the two groups each weigh less than 95% of the laminations in the other one of the two groups. Such laminations can be automatically produced on a computer-controlled die press by providing a separate punch pattern that is capable of being programmed for selected laminations. The lighter laminations can be used to counterbalance a crank without requiring additional counterbalancing weight to be added outside the motor.

Abstract: Systems and methods for controlling a draft inducer for use with a furnace. The draft inducer includes a fan for inducing a draft in the furnace combustion chamber that causes a pressure drop across a heat exchanger assembly for moving exhaust combustion chamber gases. The heat exchanger assembly has a plurality of heat exchanger elements which determine furnace capacity wherein the pressure drop across the heat exchanger assembly is affected by the furnace capacity. A motor drives the fan in response to a motor control signal and a memory stores information defining a relationship between motor speed, motor torque and parameters defining motor operation. A processor determines the speed and torque of the motor and retrieves from the memory the parameters corresponding to the determined motor speed and motor torque. The processor is responsive to the retrieved parameters for defining at least one set of speed/torque curves corresponding to a desired pressure drop across the heat exchanger assembly. A control circuit generates the motor control signal in response to the defined set of speed/torque curves to cause the motor to operate as a function of the determined motor speed and motor torque which are indicative of the furnace capacity for controlling the draft induced in the combustion chamber.

Abstract: Draft inducer systems and methods for use with a furnace. A motor drives a fan in response to a motor control signal for inducing a draft which is a function of motor speed and motor torque. A processor defines a speed/torque operating curve having a minimum desired speed and a maximum desired speed between which the speed/torque operating curve is coincident with a pressure curve corresponding to a desired pressure drop across the furnace heat exchanger assembly caused by the draft induced by the fan. The speed/torque operating curve, for a given speed above the maximum desired speed, defines a torque less than the torque defined by the pressure curve for the given speed. A control circuit generates the motor control signal in response to the speed/torque operating curve for controlling the motor torque as a function of the motor speed whereby operation of the motor is controlled so that the draft induced by the fan causes the desired pressure drop in a desired operating range between the minimum and maximum desired speeds and operation of the motor is inhibited outside the desired operating range.

Abstract: The synchronous motor comprises an armature having a plurality of teeth solid with a yoke and spaced apart by slots in which coils are accommodated. An inductor comprising a plurality of magnets borne by a sole is spaced from the armature by an air-grap. The motor is so dimensioned that the teeth of the armature have a constant cross-section over their entire height and the width of the slots alongside the tooth heads is substantially equal to the width of these heads to minimize the parasitic reluctant effect due to the slots. The motor may be linear or rotary.
