Are you thinking of putting a DC motor in series with the primary of a transformer?

This would not be a good idea because, at best, you would get pulsing DC current into the primary of the transformer and this would possibly saturate the core of the transformer.

Also, DC motors are designed so that they have very small gaps in the commutator, so there will be only very small interruptions to the supply of current to the transformer.

So, you might get very short pulses of voltage produce on the secondary, but it would be very inefficient.
