摘要： A switched reluctance drive is supplied from a power source and has a DC link, across which is a DC link capacitor. The phases of the machine are controlled by a controller which controls the switches connecting each phase winding to the DC link. The controller switches off the switches of each phase in a sequence which minimizes the peak voltage appearing on the DC link capacitor, thereby allowing a reduction in the voltage rating of the capacitor.

摘要： A sensorless switched reluctance machine includes a stator with a plurality of circumferentially-spaced stator segment assemblies that include salient stator poles and inter-polar stator slots. Each of the stator segment assemblies includes a stack of stator plates forming a stator segment core, an end cap assembly, and winding wire wound around the stator segment core and the end cap assembly. The rotor defines a plurality of rotor poles. The rotor tends to rotate relative to the stator to a rotational position that maximizes the inductance of an energized winding. A sensorless drive circuit derives rotor position and energizes the winding wire around the stator segment assemblies based on the derived rotor position. Each stator plate includes a first radially outer rim section and a tooth section that extends radially inwardly from a first center portion of the first radially outer rim section.

摘要： A method for controlling starting of a synchronous motor having an excellent starting ability and capable of coming into a commutation mode in a short time is provided. An AC current having a predetermined frequency is supplied to a field coil 81 of a synchronous motor 8 by an inverter 91, thereby starting the synchronous motor 8. By detecting a terminal voltage of the field coil 81 of the synchronous motor 8 at the starting time, and decreasing a voltage waveform component based on the AC current supplied by the inverter 91 from the detected voltage, the waveform is corrected so that the voltage waveform component based on the counter electromotive force can be confirmed (110). And after integrating the corrected waveform (111) and converting the same into a square wave (112), a phase difference between the same (104) and an output of a 120null energization waveform generating circuit 102 is detected to be fed back.

摘要： A switched reluctance machine is controlled without using a physical rotor position detector. The rotor position at start-up is determined by simultaneously injecting a current of known magnitude into two phases. The rise times of the currents are measured and used to interrogate a stored table of rise time against rotor angle for the known current level. This produces two possible rotor positions from each rise time. Comparisons of the pairs of angles yield the actual position.

摘要： In a method for current regulation of permanently excited synchronous motors for guided missiles with an electromechanical actuating drive for the rudder, the commanded current is always guided orthogonally to the magnet-wheel flow. Further: a) from measured current of two voltage phases, a measured magnitude of a current-space pointer is determined and an error value for the current is added to a desired value of the amount via a correction regulator; and b) from measured current of two voltage phases as well as from the angle command of the current-space pointer, a measurement for the angle error is determined and added to the desired angle value via a correction regulator. The method according to the invention can be implemented with little hardware expenditure and in a compact design size, even for high rotational speeds of >10,000 minnull1. Current-regulating methods used heretofore, which involve frequency response compensation in polar coordinates, cannot be used with synchronous motors, i.e. explicit determination of the angle of the space-current pointer fails in cases where the measured current disappears.

摘要： A synchronous motor control system includes a synchronous motor 1, an inverter 3 and a controller 4 wherein a current differential detecting unit 13 detects a variation of a motor current when the three phases of the motor 1 is short circuited by the inverter 3, namely at the moment when a carrier wave in a PWM signal generator 9 assumes maximum or minimum value, in a calculating unit 14 a phase null from null axis of a stationary coordinate system to a three phase short circuited current differential vector is calculated, a phase null is estimated from d axis to the three phase short circuited current differential vector by making use of d axis current id and q axis current iq on d-q axes coordinate system in the controller 4, thereafter the magnetic pole position null with respect to null axis is calculated from the phases null and null, based on thus calculated magnetic pole position null, d-q axes control units 11, 7 and 8 are constituted to control the synchronous motor, thereby a highly reliable control system for the motor which permits a detection of the magnetic pole position without affecting a state of applied voltage thereto while performing a usual PWM control with a low cost controller.

摘要： In a driving control method for a synchronous reluctance motor, a novel vector control method is employed which does not need the salient pole position angle detector. More particularly, the present invention provides a vector control method which can accurately and efficiently estimate cosine and sine signals, being rotation signals for the vector rotators. A flux vector estimator 12a uses voltage and current information of a stator to estimate a stator flux vector by dividing it into an in-phase flux vector having the same direction as a current vector and a mirror-phase flux vector determined as a difference between the stator flux vector and the in-phase flux vector. A cosine and sine generator 12b uses the estimated in-phase and mirror-phase flux vectors to generate the cosine and sine values of an intermediate angle of the angles of such flux vectors and outputs a rotation signal of the vector rotators. Thus, vector control is established.

摘要： The present invention is a motor control device for controlling current command values in relation to a permanent magnet reluctance motor which generates torque corresponding to the combined value of the torque resulting from the permanent magnet and the reluctance torque through field-weakening control in such a manner that the motor terminal voltage does not exceed the maximum inverter output voltage. In particular it controls the angle of the current relative to the motor rotor which is required for the purpose of field-weakening control, and ensures that this is stable and effective whatever torque is output.
