Title: Engine starter
Inventor: WAKITANI TSUTOMU
IPC: H02P6/28
Filed: 2002-06-27
Abstract: <P>PROBLEM TO BE SOLVED: To improve the engine starting performance by a brushless motor not having a rotor position detecting sensor.  <P>SOLUTION: An engine is rotated forward and backward in a high load area of the engine, and then accelerated and rotated forward to be started. The engine is immediately accelerated and rotated forward in a load area of the engine. The high load area and the low load area are determined on the basis of a rotating speed in starting the starting motion. An immediate start judging part 36 outputs a detection signal to a starting forward rotation control part 37, when the forward rotating speed reaches a first speed, and a second speed higher than the first speed is obtained even after the lapse of a predetermined time, after the start of the starting motion. A starting forward rotation control part 37 inputs the instruction for forward rotation to a driving part 30, and inputs a control target value for acceleration forward rotation to a drive operating circuit 29. Thereby the starting can be immediately performed from the forward rotation for positioning, in the low load.  <P>COPYRIGHT: (C)2004,JPO
