イナミックブレーキは効果的でない。l) Prior Art A conventional drive circuit is shown in FIGS. 4 and 5 attached. The switches sA', SB, SC, and SD are in two states: ON and OFF, and in the unipolar drive system, one or two coils are driven. Therefore, in the conventional example, the remaining two or three coils that are not turned on are short-circuited with isometrically high impedance, and the dynamic brake by the coil 1' that is not turned ON cannot be effectively exerted. For example, in Figure 4, the resistance R is generally thick, so the dynamic brake is not effective, and in Figure 5, the dynamic brake is not effective if the direction of the electromotive force is in the direction where no current flows due to the diode. .

Summary of the Invention The conventional drive circuit described above has the drawback of not being able to perform dynamic braking more powerfully and effectively and damping vibrations.In order to overcome these drawbacks, the switch drive method has been devised. As shown in Fig. 1, multiple switches SA, SB, SC, and SD are turned on to the side that drives the coil (bχ
