| titleOfInvention | Control system for a dc motor |
| abstract | A CONTROL SYSTEM FOR A DC MOTOR ABSTRACT OF THE DISCLOSURE A control system for a DC motor controlling the supply of power to polyphase coils by a drive transistor has a DC-DC switching converter for changing an output voltage according to an on-time ratio of the switching semiconductor, and a voltage controller for detecting a voltage drop across the drive transis-tor and for controlling the on-time ratio of the switching semi-conductor so that the voltage drop across the drive transistor may be a predetermined small value. Therefore, the control system for a DC motor has a high power efficiency but reduced noise in the polyphase coils because of the operation of the DC-DC switching converter and the voltage controller. Furthermore, the control system for a DC motor can precisely control the supply of power to the polyphase coils by the drive transistor. |
