PURPOSE:To perform the absorption or consumption of energy when an exciting current is OFF with a simple circuit configuration by connecting an energy processor between a common connector of a plurality of energy discharging diodes and a DC power source. CONSTITUTION:A control signal is supplied from a controller 10 to transistors 6-9, which are sequentially turned ON, and an exciting current is sequentially flowed to windings 1-4. For example, a surge energy when a drive transistor 6 is converted from ON to OFF is absorbed by a capacitor C1. The energy stored in the capacitor C1 is consumed in a resistor R1. When a motor is stooped and braked, and transistors 6-9 are all turned OFF. At this time, the transistor Q2 is turned ON, and one ends of the windings 1-4 are grounded. |
