Title: Motor driving circuit
Inventor: YOSHITOMI TETSUYA
IPC: H02P6/14
Filed: 1999-07-09
Granted: 2001-09-01
Abstract: The present invention relates to a kind of motor drive circuit, in which a comparator compares a full-wave signal E, which is obtained by full-wave converting a sine wave signal from a Hall element, with a trapezoidal signal G, which is obtained by sampling and holding an attenuated signal F of the full-wave signal E at the falling point of the first comparison signal D and bringing the attenuated signal at the rising point of the first comparison signal D to zero, to output a second comparison signal H. The first and the second comparison signals D, H are then added by an OR circuit to produce a sum signal K. Consequently, a drive current IL does not flow through drive coils 1, 2 in the vicinity of the first and the second halves of the phase switching point thereof. Since the drive current IL can be brought to zero before the counter electromotive force Ec is decreased in the vicinity of the first half of the phase switching point, a motor can be quiet down. Furthermore, since the drive current IL can be sustained at zero level from the vicinity of the first half of the phase switching point, drive efficiency of the motor can be prevented from lowering. Since a trapezoidal signal G can be generated from an attenuated signal F, an interval for bringing the drive current IL to zero can be provided in the vicinity of the first half of the phase switching point without fail.
