05 types of dc machines
The slip rings are the most important brush in DC machine.
swinburne's test on dc shunt machine is to predetermine the efficiency of the dc machine , but it is not accurate it is just like estimation of efficiency of dc shunt machine when it is run as a motor and a generator............................
Yes, it is normal for a welding machine to convert AC voltage to a DC voltage.
A DC motor is an electric motor that runs on direct current (DC) electricity. A DC motor is designed to run on DC electric power. Two examples of pure DC designs are Michael Faraday's homopolar motor (which is uncommon), and the ball bearing motor, which is (so far) a novelty. By far the most common DC motor types are the brushed and brushless types, which use internal and external commutation respectively to reverse the current in the windings in synchronism with rotation.
No
There are two types shaper machine they are horizontal and vertical
What motor is NOT suitable for use as a DC machine?

it is a machine which operates on the dc power source.
equation of ac machine
There are two types me dc generator 1 separately excited dc generator 2 self excited dc generator
A DC generator is a DC machine that is driven by an external rotating force. It is constructed the same as a DC motor.
yes you can configure many roles to a machine(DC) depends on the H/W capability of the machine whether it can handle the load on not.
PMBLDC machine is actually an ac machine and due to power electronics components it's output is dc ,so therefor it is called 'dc'
dril machine
Yes, it is normal for a welding machine to convert AC voltage to a DC voltage.
