発電デバイスおよびセンサ付き軸受
Document Type and Number:
Japanese Patent JP7415624
Kind Code:
B2
Abstract:
To provide a power generation device and a bearing with a sensor having the power generation device, which can improve power generation capability with a gap between a multi-pole magnet and a coil as small as possible.SOLUTION: The power generation device includes: a magnetic track (multi-pole magnet) 31 in which an N pole and an S pole juxtapose in a first direction; and a coil substrate 20 arranged opposite to the magnetic track 31, so as to generate electricity based on the relative movement of the magnetic track 31 and the coil substrate 20 in the first direction. The coil substrate 20 is constituted by a flexible substrate 21 on which a coil pattern (flat coil) 23 is provided, and includes: a coil winding part 20a having the coil pattern 23 and arranged in a position opposite to the magnetic track 31; and an extension part 20b extending from the coil winding part 20a and bent at an outer edge of the coil winding part 20a in a direction apart from the magnetic track 31.SELECTED DRAWING: Figure 4
