摘要： An electrical drive system includes an electrical machine controlled by an electronic controller and requires control signals representing quantities associated with the operation of the electrical machine. These signals may represent, for example, rotor position and flux or current. A controller includes an estimation routine to use the known magnetic characteristics of the machine and a rotor position signal to provide an estimate of current or of supply voltage.

摘要： The windings of a switched reluctance machine are supplied from a converter which is capable of providing bipolar energisation. The energisation pattern supplied to the windings is dependent on the number of stator and rotor poles in the machine and is selected to produce unipolar energisation in the rotor poles. This in turn reduces the losses in the rotor which would otherwise result from bipolar energisation. The machine may also be operated to provide energisation patterns which are adapted to provide optimum performance in different parts of its operating speed range.

摘要： An electro-mechanical transmission system, driven by a prime mover, includes two epicyclic gearsets (12,14) connected between input (23) and output shafts (43), and two electrical machines having their rotors (52,54) connected to respective elements of the two gearsets (12,14). The torque on the output shaft (43) is boosted by a controller which dumps energy from the system when one of the machines is acting as a generator and the other as a motor.

摘要： A drive system has a number of electrical machines. One machine operates as a generator supplying an output to a DC link, which in turn supplies one or more machines operating as motors to drive loads. The motors are supplied through power converters. The total capacitance of the DC link is minimised and the link kept in a stable condition by preventing it falling to a hazardous level. One embodiment prevents the phase currents adding in such a manner as to reduce the DC link voltage. Another embodiment employs freewheeling in the phase currents to prevent the DC link voltage falling below a predetermined threshold.

摘要： A switched reluctance drive is supplied from a power source. The phases of the machine are controlled by a current controller which uses an excitation strategy to minimise the supply current drawn for a particular output. The strategy alternates the excitation between two phases for a given time until the rotor moves to a desired position.

摘要： An electrical machine has phase windings composed of coils connected in parallel. A current transducer is arranged to measure the current in only one of the coils and the total phase current is determined by scaling the output of the transducer according to the number of parallel branches in the phase winding.

摘要： An electrical machine is coupled to a load which has a torque profile which varies with angle. The machine is coupled so that the torque ripple of the machine is synchronised with the torque ripple of the load in such a manner as to provide an efficient drive system which can start at any angular position. This allows the size of the electrical machine to be reduced to a point where its average torque may be below the peak requirement of the load.

摘要： A switched reluctance drive is controlled without using a physical rotor position detector. The control method estimates the standing flux-linkage associated with the phase and uses this estimate to improve its subsequent estimate of rotor position. The method works robustly regardless of whether the current is continuous or discontinuous.
