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............................
05 types of dc machines
to convert the DC into DC.............
Yes, it is normal for a welding machine to convert AC voltage to a DC voltage.
f(x)=3x ,g(x) = x2 find gof(x)
What motor is NOT suitable for use as a DC machine?

take care of the problem of induced AC field current due to armature reaction /Omara
it is a machine which operates on the dc power source.

equation of ac machine
to convert the DC into DC.............
A DC generator is a DC machine that is driven by an external rotating force. It is constructed the same as a DC motor.
what is the function of a pulley in a sewing machine
PMBLDC machine is actually an ac machine and due to power electronics components it's output is dc ,so therefor it is called 'dc'
