ANTRIEBSSTEUERSCHALTUNG FÜR EINEN ELEKTRISCHEN MOTOR |
摘要 |
The drive control circuit for an electric motor is provided. The drive control circuit includes: an original drive signal generator that generates an original drive signal, based on a positional signal which indicates a relative position of a first drive member and a second drive member of the electric motor; an excitation ratio signal generator that generates an excitation ratio signal which indicates a ratio of excitation interval to non-excitation interval of coils of the electric motor, based on a speed signal indicating a relative speed of the first drive member and the second drive member of the electric motor; an excitation interval signal generator that generates a binary excitation interval signal which specifies the excitation interval and the non-excitation interval of the coils of the electric motor, based on the positional signal and the excitation ratio signal; and a mask circuit that generates a drive signal for driving the electric motor by masking part of the original drive signal based on the excitation interval signal. |
