System for controlling brushless DC motor |
摘要 |
A brushless DC motor control system comprises a commercially available semiconductor commutator supplying field current to stator windings of the DC motor, a current detector connected to a negative-side terminal of the semiconductor commutator, a signal conversion circuit converting the output signal of the current detector to a signal correlated to the load of the motor, and a microcomputer controlling the semiconductor commutator according to the output signal of the signal conversion circuit in the motor starting mode.
