Title:
STACKING-TYPE STATOR USING MULTI-LAYERED SUBSTRATE, AND IN-CAR SENSOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/080164
Kind Code:
A1
Abstract:
The present invention relates to a stacking-type stator using a multi-layered substrate, and an in-car sensor using the same, the stator being capable of obtaining maximum torque generation in opposing rotors. The stacking-type stator of the present invention comprises: the multi-layered substrate; a plurality of coil patterns patterned in a spiral shape so as to form a plurality of turns on each substrate of the multi-layered substrate, and connected to each other through a through-hole; a hall sensor disposed on the multi-layered substrate, and disposed at the position displaced from a boundary of a rotor magnetic pole, when the rotor is in an initial state, so as to detect the magnetic pole of the rotor; and a dead point preventing yoke for setting the position of the rotor such that the position of the hall sensor is set at the position displaced from the magnetic boundary of the rotor when the rotor is in an initial state, wherein the spiral coil patterns include: a plurality of radial pattern parts respectively arranged along the radial direction; and a plurality of inner and outer connecting pattern parts for connecting the plurality of radial pattern parts to each other, wherein the coil patterns form a stator coil for a single-phase motor.
