摘要： A microcontroller with external memory interacts with a host computer or terminal via a fully isolated RS232 serial interface. An eight-bit D/A converter transforms signals generated digitally in the microcontroller. The low level analog signal at the D/A output is further amplified in a power amplifier which supplies a signal to the motor terminals of the motor to be programmed via solid state relays. The solid state relays form an array of switches which are selectively closed by a low level digit signal generated by the microcontroller and processed by digital circuits. Four signals may be modulated with a signal representing the line frequency and are used specifically in an emulation mode. The interface receives multi-function feedback signals (RPM) from the motor such as speed, memory, content, and diagnostic information. Comparators provide an integrity check of the connections (cable) and the input section of the motor (optocouplers). The comparators compare voltages and currents of a selected motor signal against pre-defined threshold levels.

摘要： A system which drives a component of a heating, ventilating, and/or air conditioning (HVAC) system in response to a system control signal such as a temperature signal provided by a thermostat. The system includes a motor having a stationary assembly and a rotatable assembly. The rotatable assembly is in magnetic coupling relation to the stationary assembly and is in driving relation to the component.

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.
