摘要： Disclosed are a synchronous motor having reduced torque ripple while having a high torque and system for driving the synchronous motor. The synchronous motor comprises a rotor (2) and a stator (3), and U-phase coils (91; 91a, 91b, and the like), V-phase coils (92; 92ab, and the like), and W-phase coils (93; 93ac and the like) are wound around sections of the yoke each located between two adjacent stator teeth (7; 7a, 7ab, and the like). The number of turns in each coil and the direction in which each coil is wound are set to compensate for a difference between a timing at which a magnetic field produced at each stator tooth is at a maximum value and a timing at which a point between magnetic poles (10, 11, 11, and the like) passes by the stator tooth as the rotor (2) rotates, the difference in timing being caused by a difference between the interval between the magnetic poles and the interval between the stator teeth.

摘要： A drive circuit includes an ac network and first and second network rectifier/inverters (which can be active or passive) that are connected to the ac network in parallel. A first PWM rectifier/inverter is connected to the first network rectifier/inverter through a first dc link. A second PWM rectifier/inverter is connected to the second network rectifier/inverter through a second dc link. A first two-layer stator winding having a plurality of individual stator coils is connected to the first PWM rectifier/inverter and a second two-layer stator winding having a plurality of individual stator coils is connected to the second PWM rectifier/inverter. The stator coils of the first stator winding and the stator coils of the second stator winding are interconnected such that, in use, the vector sum of voltages across the stator coils in the first stator winding is substantially equal to the vector sum of voltages across the stator coils in the second stator winding. This has the advantageous effect of reducing the PWM frequency current harmonics flowing in the first and second stator windings.

摘要： Disclosed is a controller of a grid coupled type doubly-fed induction generator having a multi-level converter topology, which can control the doubly-fed induction generator having a high voltage specification and can perform a fault ride-through function, an anti-islanding function and a grid voltage synchronization function required for a dispersed power generation facility. The controller makes a H-bridge multi-level converter generate a three-phase voltage waveform resulted from the structure that single-phase converters each being composed of a 2-leg IGBT are stacked in a serial manner, and controls a rotor current so as to make the rotor coil of the doubly-fed induction generator in charge of a slip power only. The boost converter is composed of a 3-leg IGBT and a boost inductor generating a direct current voltage of its source required for the H-bridge multi-level converter.

摘要： Exemplary embodiments provide a method of controlling a doubly-fed electric generator using a frequency converter having a torque and flux controller. The frequency converter is connected to a rotor of the generator. The frequency converter calculates a stator flux positive sequence component from a stator flux. A rotor flux amplitude reference and an estimated torque is then calculated by using the stator flux positive sequence component. The frequency converter selects a voltage vector to steer the rotor flux by using the rotor flux amplitude reference and the estimated torque.

摘要： A motor controller for an axial-gap motor permits a reduced size of the entire system of including a drive circuit and a power source of the motor, reduced cost, and higher reliability to be achieved by controlling the energization mode of the motor. The motor controller has a torque command determiner which inputs a first DC voltage to a first inverter at least either when a rotor is at a halt or when the number of revolutions of the rotor is a predetermined number of revolutions or less, supplies a field axis current for changing the magnetic flux of a field of the rotor to a first stator from the first inverter such that the amount of energization is temporally changed, converts an induced voltage developed in a second stator by the supplied field axis current into a second DC voltage by a second inverter, and outputs the second DC voltage, thereby charging a second battery.
