<P>PROBLEM TO BE SOLVED: To provide a motor drive that starts a brushless DC motor, in a short time using a simpler constitution. <P>SOLUTION: When the motor drive 1 starts a brushless DC motor 2 through forced commutation, a gate drive circuit 5 limits the current flowing through the windings 2U-2W of the motor 2 to the upper limit level, set higher than the level of a current flowing, when the motor 2 goes into steady state steady rotational state. <P>COPYRIGHT: (C)2008,JPO&INPIT |
