Electric motor of spring setting device in air automatic switch

Electric motor includes the first frame provided with a hole to insert the bearing and a pair of holes to insert brush holders; the second frame having the hole to insert bearing and through hole for the shaft; bearings, each of which is inserted in holes for insertion of bearings, which are made in the first and the second frames; shaft with possibility of turn and connected to the first and the second frames through bearings due to the fact that shaft passes via through hole for shaft in the second frame; collector connected to shaft; stator winding rotating the shaft; brush holder connected to stator winding through electric line; and brush inserted in brush holder in position of elastic spring support for bringing it into contact with collector; at that, brush holder has the shape of rectangular parallelepiped and includes the plate interlocking the lower part and arranged at the bottom for interlocking of lower part; opened by being unbent during unbending process, and part fixing the electric line so that electric line can be attached to external wall by being bent during bending process.

End plate of stator of commutator motor, and commutator motor with such plate

End plate of stator for stack (2) of stator core of commutator motor (1), namely universal motor, namely to be used in household appliance, with connecting terminal (11) having connection elements (24, 38, 39, 40, 41) for connection of wires (51, 52, 53, 531, 532, 61, 62, 63, 631, 632) of stator winding and slip connector (27, 28) with contact elements (25) for receiving external plug contact of motor (48) and electric contact to it. At that, each of connection elements (24, 38, 39, 40, 41) is electrically connected to the appropriate contact element (25). On end plate (10) of stator there located is only one connecting terminal (11). At that, for electric contact of at least one more internal electric structural element (13, 14, 15, 31) of commutator motor (1), in slip connector (27, 28) there located is at least one more contact element (25) corresponding to structural element (13, 14, 15, 31).
