Title: Dc brushless motor system
Inventor: NOMOTO TETSUO
IPC: H02P6/182
Filed: 2000-02-15
Abstract: PROBLEM TO BE SOLVED: To provide a DC brushless motor system capable of rationally transferring from a start of an inverter to an ordinary operation. SOLUTION: The DC brushless motor system drives an inverter by a position detection signal Su1 obtained by detecting a rotary position of a rotor to operate a motor. It is controlled in response to the number of the detection signals obtained after starting the position detection mask time tf for specifying the detection of the detection signal. A communication delay time tg for specifying a communication time point Ut continued to the detection signal is controlled similarly corresponding to the number of the detection signals. An increasing ratio of a drive frequency of the inverter is controlled to a larger increasing ratio than that when ordinarily operated and controlled. These correspondence and the increasing ratio are suitably combined, and conducted only during a period from the start of the mask time tf to the arrival of the rotor at a predetermined rotational speed.  Since the control corresponding to the number of the detection signal from the start of the mask time is conducted, even if a load of the rotor is changed in a pulsating manner on the way, it can be early transferred to the stationary operation.
