dc series motor due to its high statting torque. In fact ,
the dc series are never operated under no-load conditions,
they are always driven with the load.

If an electrical component has a positive temperature coefficient, how come such components have high power losses due to heat if current decreases when resistance increases? assuming power given by I^2*R whereby the Resistance is infinite.
