1. A motor with bidirectional terminals comprising:
a yoke assembly forming a magnetic field;
an armature assembly comprising a coil wound around a core slot formed in a core, disposed inside the yoke assembly, coupled to a rotation shaft, and configured to rotate relative to the yoke;
a brush card assembly fixed to one side of the yoke assembly and having a brush installed therein to supply power to a commutator installed on the armature assembly; and
a plurality of brush terminals, each of the plurality of brush terminals installed on left and right sides of an upper surface of the brush card assembly to protrude from the upper surface and connected to a power supply terminal to supply power to the brush card assembly,
wherein each of the plurality of the brush terminals comprises a pair of terminals having a (+) pole and a (−) pole,
wherein the brush card assembly includes:
a brush card housing with an installation space therein;
a choke coil installed on one side of the brush holder and supplying power to the brush; and
a lead wire made of a steel wire and electrically connecting each of the brush terminals and the choke coil, and
wherein the lead wire includes:
a (+) pole lead wire connected to a (+) pole terminal on a left side of the brush card housing and another (+) pole terminal on a right side of the brush card housing, respectively, and connected to the choke coil; and
a (−) pole lead wire connected to a (−) pole terminal on the left side of the brush card housing and another (−) pole terminal on the right side of the brush card housing, respectively, and connected to the choke coil.
