Title: Revolution detection circuit for dc brushless motor
Inventor: SATO HIDEYA
IPC: H02P6/06
Filed: 2002-11-18
Abstract: <P>PROBLEM TO BE SOLVED: To provide a circuit for detecting by a simple method the revolution of a DC brushless motor, which performs PWM revolution control in a sensorless manner.  <P>SOLUTION: A pulse is generated by comparing a detected voltage of one phase U<SB>+</SB>in a stator coil of an n-phase of the DC brushless motor with a reference voltage by a comparator 7. The pulse contains a mixture of a drive pulse to the output stage and an induced voltage, and switching noise. After removing the switching noise by making this pulse string pass through a low-pass filter 9, the pulse is outputted at a point where the logical levels of both of the pulses coincide with each other, by taking the logical AND of an drive pulse output and the induced voltage with an AND circuit 6. At this time, since the pulse is not outputted from the comparator 7 if a motor is stopped to cause the lowering of the detected voltage, the pulse is not generated from the AND circuit 6. The pulse accompanied by rotation can thus easily be outputted, resulting in easy detection of the revolution of the DC brushless motor.  <P>COPYRIGHT: (C)2004,JPO
