The DC traction motor is composed of main components such as rotor armature winding, stator excitation winding, frame and brush commutation device. Traction motors mainly use series-excited DC motors. After the dc motor commutator is connected to ...
Generally speaking, the characteristics of high-altitude climate are mainly: thin air, low air pressure, low temperature, large temperature change, low oxygen and water vapor content, the influencing factors of the commutator in the high-altitude wor...
At present, the conduction between the rotating part and the static part of the product may be a very important accessory. It has a good sliding touch effect, and also has special requirements compared with resistivity and contact resistance. General...
Contact sheet: The contact sheet is a constituent part of the commutation equipment. The contact sheet is not a special copper sheet, but the protruding contact on the copper sheet. The requirements are relatively high; many are sterling silver, silv...
The forging process includes: cutting the material to the desired size, heating, forging, heat treating, cleaning and inspection. In small-scale manual forging, all these operations are carried out in a small space by several forges. They are all exp...
In the design of the diameter of the reversing equipment, the maximum speed limit of the contact between the reversing equipment and the carbon brushes must be considered first. The radius of the cylindrical reversing equipment must meet the contact ...
Demand for electric desks, general capital, and general affairs for electric machines. In the event of a failure or problem, the scholarship of the scholarship, the scholarship, and the scholarship of the scholarship. Commutator, commutator, demand a...
(1) When the carbon brush load of the motor is suddenly disconnected, the speed of the motor will rise so high that it will cause a speeding accident. If there is no special person to manage it, anti-speeding measures should be taken. For example,...
