Description

technical field [0001] The invention relates to an electric motor for rolling auxiliary transmission. Background technique [0002] The DC motor for rolling mill auxiliary drive is a kind of DC motor for metallurgical lifting, which is suitable for rolling mills, cranes, elevators and electric shovels, etc. Due to the high moment of inertia, low overload capacity, and slow speed response of the existing DC motors for auxiliary drives in rolling mills, the motors cannot be used normally, their service life is reduced, and they are easy to burn out. At the same time, they cannot withstand rapid and frequent startups, Braking and reversing, its reliability and speed regulation performance are poor, and it cannot adapt to the shortcomings of working under the power supply of the thyristor. The whole motor cannot withstand vibration and impact. All windings are insulated, which cannot ensure high insulation stability and good heat dissipation. . In addition, the connection betw...

Problems solved by technology

Due to the high moment of inertia, low overload capacity, and slow speed response of the existing DC motors for auxiliary drives in rolling mills, the motors cannot be used normally, their service life is reduced, and they are easy to burn out. At the same time, they cannot withstand rapid and frequent starts, Braking and reverse, its reliability and speed regulation performance are poor, and it cannot adapt to the shortcomings of working under the power supply of the thyristor. The whole motor cannot withstand vibration and impact. All windings are insulated, which cannot ensure high insulation stability and good heat dissipation.

In addition, the connection between the armature winding and the rising piece of the commutator has poor mechanical reliability
