摘要： Provided is a method for suppressing 24th-order noise of an electric motor on the basis of harmonic current injection. The method comprises: converting a three-phase current of an electric motor, which is collected by a three-phase current sampling module, into an id feedback current and an iq feedback current; injecting, into the iq feedback current, a harmonic current iqcomp of a 6th-order electrical frequency, and calibrating the values of a compensated 6th harmonic amplitude igain of the iq feedback current and an initial phase angle θoffset, so as to offset a 6th-order harmonic component in the iq feedback current; making an id instruction current and the id feedback current, and an iq instruction current and the iq feedback current respectively pass through a PI controller, and then performing adjustments to obtain a ud* control voltage and a uq* control voltage; and transforming the ud* control voltage and the uq* control voltage into a uα* voltage and a uβ* voltage by means of inverse Clark transformation and inverse Park transformation, such that the electric motor is controlled by means of the uα* voltage and the uβ* voltage, thereby achieving the aim of suppressing 24th-order noise of the electric motor.

摘要： A variable speed constant frequency (VSCF) power generator includes a rotating direct current (DC) power source, rotating multi-phase generator main field windings 114 to generate a rotating alternating current (AC) power, and a rotating inverter 112 configured to control alternating current (AC) generator field windings in response to output AC power generated by the VSCF power generator and DC power from the rotating DC power source. At least one generator main field sensor 124, 126 outputs a generator main field feedback signal based on the rotating AC power applied to the rotating multi-phase generator main field windings. Stationary multi-phase generator armature windings 128 output constant voltage constant frequency AC power controlled by the rotating AC power. An electronic rotating power line communication (PLC) controller 116 generates a control signal that adjusts the rotating AC power based on the rotating generator feedback signal, where the output AC power is controlled by adjusting the rotating AC power.

摘要： A method and a system for determining deterioration of permanent magnets of an electric apparatus to be inspected that facilitate determination without the need to remove the electric apparatus from a facility where it is installed. If the electric apparatus to be inspected is a three-phase linear motor, a current detector is used to acquire currents. A three-phase/two-phase conversion section converts the acquired currents into an α-axis current command and a β-axis current command. A locus of a current vector is computed based on the α-axis current command and the β-axis current command. A comparing and determining section compares the computed locus with a standard upper limit value stored in a storage means. If the number of times that the locus of the current vector exceeds the standard upper limit value exceeds a predetermined value, it is determined that the permanent magnets have been deteriorated.
