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 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 motor assembly includes a stationary assembly having a plurality of winding stages adapted to be electrically energized to generate an electromagnetic field and a rotatable assembly including a plurality of permanent magnet elements in magnetic coupling relation with the stationary assembly. The motor assembly also includes first and second substantially flat end members parallel to each other and having inner facing sides between which the stationary assembly and the rotatable assembly are located. Each of the members has an outer side opposite its inner side. Control circuitry is connected to the winding stages and positioned adjacent the outer side of the first member, for applying a voltage to one or more of the winding stages at a time and for commutating the winding stages in a preselected sequence to rotate the rotatable assembly about an axis of rotation. A cap on the outer side of the first member forms a closure with the first member within which the control circuitry is located. A connecting element engages the second end member and the cap and is adapted to urge the second end member and the cap toward each other thereby supporting the first end member, the stationary assembly and the rotatable assembly therebetween. Alternatively, an adapter having first and second opposite sides may be positioned between the first end member and the cap.

摘要： Electrical load powering apparatus has a load connection, a high voltage supply connection and a common, and includes electronic means for switching the high voltage supply connection to the load connection. The electronic switching means has an input and is responsive to a control voltage difference between the input and the load connection. The load connection is subject to high voltage excursions relative to the common due to the switching. An electronic control circuit for use in the electrical load powering apparatus includes a circuit having an active device for providing at least one pulse output relative to common and having at least one inherent capacitance. A circuit connected to the load connection inverts the pulse output of the circuit having the active device to produce the control voltage difference between the electronic switching means input and the load connection. An additional circuit charges the inherent capacitance of the circuit having the active device when one of the high voltage excursions occurs. An electronically commutated motor system, a regulated power supply and laundry apparatus utilizing the electronic control circuit are set forth. Methods for controlling the motor system, for operating apparatus for switching high voltage DC and for controlling electrical load powering apparatus generally are also described.
