A brush holding device is disclosed. The brush holding device comprises a brush holder (2); a plug (3) extending radially outward from the brush holder (2); a first plug contact element (31) and a second plug contact element (32) that are fixed to the plug (3) and extend toward the brush holder (2); and a first circuit board (4) having a first contact area (45) and a second contact area (46).The first plug contact element (31) and the second plug contact element (32) are connected with a brush through a choke coil, are made of an electrically conductive material and supply electric power to the brush. The first contact area (45) has a first slit (61), the second contact area (46) has a second slit (62), wherein the first plug contact element (31) and the second plug contact element (32) are respectively accommodated in the first slit (61) and the second slit (62). The first circuit board (4) is inserted into the first plug contact element (31) and the second plug contact element (32). The first contact area (45) and the second contact area (46) are electrically connected to the first plug contact element (31) and the second plug contact element (32) by solder or welding. The first circuit board (4) has electric-magnetic interference suppression components (41, 42, 43, 44), which are electrically connected to the first contact area (45) and the second contact area (46), and are directly or indirectly grounded. |
