Squirrel cage motor
we can either use dc series motor or induction machine ,but dc supply is not easily available so we use induction motor ,
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............................
capacitor start motor
dc series motor
no you can't use dc motor to power hydro turbine ?
What motor is NOT suitable for use as a DC machine?
DC series motor is suitable for the tractions

You need suitable DC power source to run it.

PMBLDC machine is actually an ac machine and due to power electronics components it's output is dc ,so therefor it is called 'dc'
A shunt-wound DC motor can maintain its speed well when the load torque varies.
A DC generator is a DC machine that is driven by an external rotating force. It is constructed the same as a DC motor.
shunt type dc motor use in train fans
It is doubly excited if it is sparately excited dc motor, singly excited if it is self excited machine
