Was ist ein "nose-suspended" traction motor?Nose Suspended Motor
The following diagram shows the layout of the traditional DC motor mounted in a bogie as a "nose suspended motor".
In electric trains or locomotives, the DC motor was traditionally mounted in the bogie frame supported partially by the axle which it drove and partially by the bogie frame. The motor case was provided with a "nose" which rested on a bracket fixed to the transom of the bogie. It was called a "nose suspended motor" (see diagram above) and is still common around the world. Its main disadvantage is that part of the weight rests on the axle and is therefore unsprung. This leads to greater wear on bogie and track. Nowadays, designers try to ensure all the motor weight is sprung by ensuring it is carried entirely by the bogie frame - a frame mounted motor.
