The pigtail in a DC machine serves as a flexible electrical connection that allows the brushes to maintain contact with the commutator segments while accommodating movement due to vibration or thermal expansion. It helps ensure reliable electrical conductivity and minimizes wear on both the brushes and the commutator. Additionally, the pigtail is designed to prevent the brushes from becoming dislodged or misaligned during operation, contributing to the overall efficiency and longevity of the machine.
What motor is NOT suitable for use as a DC machine?
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............................
it is a machine which operates on the dc power source.
05 types of dc machines

equation of ac machine
A DC generator is a DC machine that is driven by an external rotating force. It is constructed the same as a DC motor.
PMBLDC machine is actually an ac machine and due to power electronics components it's output is dc ,so therefor it is called 'dc'
Yes, it is normal for a welding machine to convert AC voltage to a DC voltage.
