PURPOSE:To simplify the circuit configuration by interposing a thyristor phase controller in one phase of circuits for connecting a power source and a linear motor. CONSTITUTION:A reversible conduction phase controller 3 in which thyristors 3a, 3b are connected in anti-parallel to each other is connected to one phase of circuits for connecting the output terminals 1a-1c of a 3-phase AC power source 1 to the input terminals 1a-2c of a linear motor 2. In this manner, the number of conducting control elements can be reduced, and the firing control circuit can be simplified. |
