Which part of the DC motor can sustain maximum temperature rise?
Right Answer is:
Commutator
SOLUTION
- The commutator is made up of copper segments.
- This copper segment is insulated from each other with the help of mica.
- Mica has a very high dielectric stress of about 1180 kV/cm and the next best is Diamond.
- It can withstand high temperatures, up to 600 deg C.
