Claim 0:
1. A motor driver having a startup adjusting mechanism, which is applicable to a motor, the motor driver comprising:
a steady-state detector circuit connected to the motor, and configured to detect data for driving the motor to rotate stably for outputting a steady-state detected signal in a pre-operation;
a startup waveform pattern circuit connected to the steady-state detector circuit, configured to store a plurality of startup waveform patterns, configured to select one of the plurality of startup waveform patterns according to the steady-state detected signal, and configured to output a startup waveform pattern signal according to the one of the plurality of startup waveform patterns that is selected;
a startup waveform generator circuit connected to the startup waveform pattern circuit, configured to determine a plurality of waveforms of a first startup waveform signal, and configured to output the first startup waveform signal according to a plurality of waveforms of the startup waveform pattern signal;
a motor controlling circuit connected to the startup waveform generator circuit, configured to output a startup controlling signal according to the first startup waveform signal, and configured to output a steady-state controlling signal; and
a motor driving circuit connected to the motor controlling circuit and the motor, configured to output a startup driving signal to the motor to start up the motor according to the startup controlling signal, and configured to output a steady-state driving signal to the motor to drive the motor to rotate stably according to the steady-state controlling signal after the motor is started up.
