ARRANGEMENT FOR STARTING BRUSHLESS MOTOR

摘要

The activation control apparatus includes a driving logic circuit for controlling the revolution speed and phase of a motor, a power driving circuit for driving the motor by the output signal of the driving logic circuit and an activation control signal, an overload detector for checking whether the driving voltage of the motor is a normal state or an overload state, and an activation control circuit for supplying a motor activation signal and a re-activation control signal to the power driving circuit, thereby protecting the motor from a re-activation trial.
