very little
Because tests on a dc motor are always done using dc.
The field current of a dc motor provides the magnetic field that allows the motor to develop a torque when current flows through the armature..
on adding load on a dc shunt motor, the amount of current and torque will increase. but terminal voltage will decrease
the sprrd regulation is cnsiderably improved.
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
6V dc motor
A synchronous motor is an ac motor that does not run on dc.
A dc series motor can work on dc and ac because dc motors are totally reversible.
Yes it can and the otherway aroud a DC motor can be used as a dynamo
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.
the three phase dc motor never seen yet motor eaither 3phase m/r or dc motor.
dc series motor is used for traction...
