Abstract: In a resonant motor system, an electrical motor having a stator with one or more windings, a rotor which may or may not be wound, and an air gap between the stator and the rotor for storing magnetic energy such that the motor exhibits a definite electrical inductance deployed with a drive combination including a capacitance connected in series with the inductance of the motor to form an LCR circuit therewith. Phased provision of DC power to the LCR circuit causes the circuit to oscillate, which excites the motor. The DC power is provided in synchronism with the rotation of the rotor in order to maximize torque produced by the motor.

Abstract: A drive circuit for an electric machine is disclosed. In one example, the drive circuit utilizes a bootstrap capacitor and a bootstrap diode, followed by a regulator, as a basis for driving a gate of a power stage of an inverter. The regulated voltages from the bootstrap capacitor and bootstrap diode eliminate the need for using a transformer for driving the gate of the power stage of the inverter.

Abstract: A method and apparatus for operating an electric motor is presented. A transmit magnetic field is received at a group of receive coils having a group of axes oriented substantially parallel to magnetic field lines from a transmit coil and having a group of resonant frequencies. A resonant frequency in the group of resonant frequencies is different from other receive coils in the group of receive coils. A receive magnetic field is generated at a receive coil in the group of receive coils having the resonant frequency when the transmit magnetic field has a selected frequency matching the resonant frequency. The receive magnetic field attracts a rotor in the electric motor.

Abstract: To control the speed of an alternating-current drive capacitor motor of a centrifuge, the motor is connected to the bridge arm of a single-phase inverter. The bridge arm is connected at each of its ends to the midpoints of a series circuit of two capacitors and two field-effect transistors, these series circuits being connected in parallel with one another and connected to the output of a rectifier operated by the a.c. voltage supply. During operation, the capacitors are discharged by means of triggering the field-effect transistors alternately via the capacitor motor, the triggering being performed via a microprocessor serving as a pulse generator.

Abstract: A single power converter is capable of drawing low distortion current from an AC line and delivering DC or AC power to a load. The single power converter is used to independently control the input current and the output current. The power converter transformer has an output winding which is controlled by pulse-width modulation (PWM) and a frequency controlled boost winding for controlling input current.
