Question
which one is correct about permanent magnet DC machine (PMDC)?
The flux of the PMDC is variable like shunt DC motor
Large residual flux and large coercive magnetizing intensity are desirable for PMDC poles
usually a paramagnetic material is used to build the poles of PMDC
The copper losses of series DC machine is less than PMDC
