PURPOSE:To obtain a high-speed, high-torque and efficient reluctance type motor. CONSTITUTION:When the current application to one exciting coil 32 is stopped, the magnetic energy accumulated in a magnetic core is prevented from circulating into a power source side by the diode 49a for prevention of reverse currents, but is charged into a small capacity of capacitor 47a so as to maintain it at high voltage, so the drop of a current becomes rapid. Though the next exciting coil 32d is supplied with a current after a certain time, the voltage applied at this time becomes a charge high voltage of the capacitor 47a, so the current starts up quickly. Since the rise of the current application of the exciting coil 32a and the drop becomes quick, it can rotate several ten thousands times per minute. A means for replenishing the energy loss by copper loss and iron loss by applying a current to an inductance coil at current application to the exciting coil 32a and charging the magnetic energy of both into the capacitor 47a and applying a current to the next exciting coil to be supplied with a current is also adopted. |
