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 motor with positive torque parking positions. The motor includes a rotor which is rotatable about an axis of rotation and a stator in magnetic coupling relation with the rotor. The stator includes a plurality of teeth each having a radially extending shaft and an axially extending face. The faces of the stator teeth define an aperture for receiving the rotor and the faces of the stator teeth and the rotor define an air gap therebetween. Each stator tooth has a notch in its face that is approximately at least as wide as the shaft of the stator tooth so that the stator has a magnetic configuration relative to the rotor for parking the rotor in a rest position corresponding to a positive torque starting position. The motor also includes a winding on the shafts of the stator teeth and a control circuit for controlling current in the winding whereby an electromagnetic field is produced for rotating the rotor at a desired speed or torque during operation of the motor.

摘要： In a five-axis magnetic bearing, each of two combined radial and axial magnetic bearing structures includes a radial magnetic stator and a radial magnetic rotor. A shaft supports the rotors of the bearing structures. Each rotor and stator have an asymmetrical orientation such that the bearing structure is capable of creating a force in an axial direction when the bearing structure is excited. A creatable axial force of a first one of the bearing structures is capable of being in sufficient opposition to a creatable force of a second one of the bearing structures so as to maintain the shaft assembly in a desired axial position. The asymmetrical orientation may include, for example, a rotor being physically offset from a stator or a spatial distinction between a surface region of a respective rotor and a surface region of a respective stator. Examples of spatial distinctions include material extensions, notches, and holes. Each bearing structure can be controlled by four stator portions (actuators) with each actuator being supplied with current signals representative of a common mode axial force command and a respective differential radial force command.
