」：す、電力効率が非常に悪い。However, in the circuit configured as described above, the switching signal S1. When S2 is input to terminals 5 and 9 by switching alternately at regular intervals, diodes 2. An induced current flows in a closed loop formed by the resistor 3 and the coil 10 or the diode 6, the resistor 7, and the coil 11, respectively. That is, when the switching signal S1 changes from ON to OFF, the transistor 4 changes from conductive to disconnected, and the magnetic energy stored in the exciting coil 10 is transferred to the diode 2. A closed loop is formed by the resistor 3 and the excitation coil 10, and an induced current A flows. The magnetic energy is converted into heat by the resistor 3 in the closed loop, and although the induced current A decreases exponentially as shown by the broken line in Figure 2 (a), the induced current A completely disappears. takes a considerable amount of time. On the other hand, switch signal S2 changes from ON to O.
Even when the FF becomes FF, an induced current B flows, and the magnetic energy is converted into heat by the resistor 7 in the closed loop, thereby attenuating the induced current B. However, it is unlikely that the induced current B will completely disappear υ It takes time. Therefore, the rotation of the rotor of the pulse motor is delayed to the point where the residual magnetic field within the pulse motor generated by the induced currents A and B disappears, resulting in slight uneven rotation. Furthermore, in order to eliminate the induced currents A and B, the magnetic energy is converted into heat by the resistors 3 and 7, resulting in very poor power efficiency.
