Electric motor including a flexible printed circuit board stator

摘要

A motor having a compact and lightweight design may include a stator provided by a flexible printed circuit (flex circuit) 26. The flex circuit 26 may include a plurality of etched windings that provide coils 30A-30L for a plurality of motor phases. A printed circuit board 32 of the motor may provide various device functions such as electrical commutation. The motor may be used in various applications such as a cooling fan for device electronics and gyroscopic applications.
