Brushless DC motor, pump, and electronic apparatus |
摘要 |
A brushless DC motor includes a substrate fixed to the center of a stator core. The substrate includes a central substrate and an arm substrate extending from the central substrate to a salient pole. The arm substrate is accommodated between coils. A driver IC is mounted on the central substrate, and a magnetic pole position sensor is mounted on the arm substrate. This structure provides a thin brushless DC motor which assures good motor performance and stable noise and vibration levels, improves motor efficiency, and reduces the number of components and assembling steps.
