摘要： A single phase permanent magnet motor includes a rotor, a stator, and a quadrature axis winding positioned out-of-phase from a main winding of the stator for generating an output signal representative of rotor angular position. An integrator can be coupled to the quadrature axis winding for phase retarding the output signal, and a comparator can be coupled to the integrator for detecting zero crossings of the phase retarded output signal to provide a commutation signal. The quadrature axis winding can be positioned about ninety electrical degrees out-of-phase from the main winding of the stator, and the integrator can be adapted to phase retard the output signal by a number of degrees which decreases as a speed of the motor increases. At low speeds the phase retard is preferably at about ninety degrees so that the phase retarded signal becomes in-phase with the main stator winding back EMF voltage. The motor may further include a rectifier coupled to the quadrature axis winding for rectifying the output signal, and a lowpass filter for filtering the rectified output signal to provide a signal proportional to velocity. Also the single phase motor is commutated for maximum torque production.

摘要： A single phase motor system and method for preventing excessive circulating currents in the motor. The motor has a power supply link including power switches responsive to a motor control signal for connecting the motor winding to a power supply in alternating on and off intervals. A current sensing circuit senses current in the power supply link during the on intervals. A current regulation circuit generates a current regulation signal representative of the difference between the sensed current and a peak regulated current level that is a function of desired motor speed and/or torque. An overcurrent circuit generates an overcurrent signal in response to the sensed current exceeding a maximum current level greater than the peak regulated current level. The motor also has a control circuit responsive to the current regulation signal for generating the motor control signal thereby to regulate current in the winding and control the motor speed and/or torque. At least one of the on intervals is greater than or equal to a minimum interval which is independent of the current regulation signal. The control circuit is also responsive to the overcurrent signal for causing the power switches to disconnect the winding from the power supply thereby to prevent excessive currents from circulating in the motor.

摘要： A control system and method for an electronically commutated motor having a stationary assembly with a plurality of winding stages for carrying a motor current in response to application of a voltage having a magnitude subject to variations, the motor further having a rotatable assembly. The control system is adapted to receive control pulses having a duty cycle which is a function of a desired operating torque or speed for the motor. The control system and method are responsive to the motor current for generating a pluse width modulated (PWM) series of pulses having a pulse repetition rate having a duty cycle which is a function of the duty cycle of the control pulses. The PWM series of pulses are supplied to the commutating circuit as a pulsed signal whereby the operating torque or speed of the motor is a function of the duty cycle of the control pulses and is substantially independent of variations in the magnitude of the applied voltage. The control system may be part of a draft inducer apparatus or method for use with a combustion chamber having an exhaust outlet including a fan for moving air through the exhaust outlet and thereby to induce a draft in the combustion chamber. A pressure sensor connected to the motor control apparatus may be located within the exhaust outlet.

摘要： A system and methods to provide a desired operating area for a motor driving a fan for inducing a draft in a vent of a heating, ventilating and air conditioning system. The motor includes a stationary assembly and a rotatable assembly. The stationary assembly includes windings adapted to be energized in at least one preselected sequence. The rotatable assembly is in magnetic coupling relation to the stationary assembly and in driving relation to the fan. The system includes a commutating circuit responsive to a pressure signal representative of a minimum air pressure in the vent and a tachometer signal representative of the speed of the motor for controlling power switching devices. The power switching devices selectively connect a power supply to the windings to provide a motor current to the windings in the preselected sequence to produce an electromagnetic field for rotating the rotatable assembly at a motor operating speed. A control circuit limits the motor current provided to the windings by the power switching devices to a predetermined maximum current which is a function of the motor operating speed as represented by the tachometer signal. In this manner, the control circuit inhibits operation of the motor outside a pre-defined speed/current region by preventing the motor current at a particular motor operating speed from exceeding the predetermined maximum current. The predetermined maximum current is within the pre-defined speed/current region and corresponds to the particular motor operating speed so that excessive heat is not generated by the system.
