An asynchronous traction motor consists of a casing, where it is fixed a stator and a rotor with a short-circuited winding, two bearing units, fixed to the casing a terminal box with high-voltage box having a high-voltage block, to which output buses of the stator winding are connected, and a low-voltage winding with a low-voltage terminal block. Output ends of conductors of control circuit sensors installed at the motor are connected to the low-voltage terminal block. Boxes are located from side faces of the casing, the distance between boxes is not less than length of casing side face. In inner wall of high-voltage terminal box it is made an opening, wherein an insulator is installed. Fixing elements of the high-voltage terminal block are equipped with inside cylindrical dielectric elements, on which it is installed. |
