Brushless DC motor control utilizing a ROM |
摘要 |
The power switch driver circuit of a brushless DC motor control ensures synchronous operation by utilizing a ROM addressed by motor shaft position sensors. Excess current drawn by the motor windings is sensed by a detector which provides an additional bit of address input to correct the condition. The address input may also be modified by a bit signifying forward or reverse operation of the motor.
