Losses are undesirable in any kind of electric motor (DC, AC, stepper, servo, synchro, etc.) because they waste power, can cause excessive heating in the motor, can accelerate wear-out and cause premature failure of the motor, etc. Ultimately they are undesirable because the problems above increase the need for maintenance, thus increasing lifetime cost of the motor. It all comes down to money.
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
6V dc motor
A dc series motor can work on dc and ac because dc motors are totally reversible.
To state it simply, a DC brushless motor is not a DC motor. It is an AC motor with an inverter (or electronic commutator) on the front end to make the AC, so you can use a DC input.
dc series motor is used for traction...
Yes you can turn a motor into a generator, if it is a permanent magnet motor.
Copper is not something that is calculated. The amount of copper might be, or copper losses / load losses, might be, but "copper" is not calculated.

6V dc motor
A synchronous motor is an ac motor that does not run on dc.
A motor uses electricity; it does not produce it. If you are somehow using a DC motor as a generator, then it will produce power equal to the input power minus the motor losses. If the input power is you spinning the rotor, the output power will be directly proportional to how much work you put into spinning the rotor.
Yes it can and the otherway aroud a DC motor can be used as a dynamo

the three phase dc motor never seen yet motor eaither 3phase m/r or dc motor.
dc series motor is used for traction...
Yes. You can "Meg" any motor, AC or DC.
