MOTOR DRIVE DEVICE AND ELECTRIC EQUIPMENT UTILIZING SAME |
摘要 |
Brushless DC motor (4) is driven based on a first or second waveform signal output from switching determination unit (11), which switches outputting so that a first waveform signal by first waveform generation unit (6) is output when the speed of rotor (4a) is determined to be lower than a predetermined speed, and a second waveform signal by second waveform generation unit (10) is output when the speed of rotor (4a) is determined to be higher than the predetermined speed. Thereby, drive is stable even at high speed / under high load, and a driving range is extended. |
