As far my knowledge a dynamo is a motor which provides electricity when the rotor shaft is rotated. My Question to be brief is if I connect multiple dynamos in a single shaft will I get more current? Will the current be in AC or DC? What will happen if I replace dynamos with 12 volt DC motors? Will the current output (Ampere) be higher or the Voltage?

  • $\begingroup$ The power output is limited by the power input and the losses. $\endgroup$ – Solar Mike Jun 9 '20 at 10:42
  • $\begingroup$ so how is that a commercial wind power plant can yield Terra watts of power? Is there any way to get out more juice out of a single windmill? $\endgroup$ – Dhrubojyoti Dey Jun 9 '20 at 10:43
  • $\begingroup$ Because they have multiple wind turbines each producing power from different parts of the airstream ie wind. Back to power out = power in minus losses... $\endgroup$ – Solar Mike Jun 9 '20 at 10:46

  • $\begingroup$ With wind generators, size matters. Large wind turbine driving large generator = MW of power. $\endgroup$ – StainlessSteelRat Jun 9 '20 at 20:46

A dynamo will give DC output. An alternator will give AC output.

If I connect multiple dynamos in a single shaft will I get more current?

Yes, if the mechanical drive continues to run at the same speed. Adding electrical load will add mechanical load to the mill.

Will the current be in AC or DC?

Dynamos and alternators.

What will happen if I replace dynamos with 12 volt DC motors?

Brushed DC motors and brushed dynamos are pretty much the same thing. A motor can be used as a dynamo.

Will the current output (Ampere) be higher or the Voltage?

Connecting dynamos of the same type in parallel will increase the output current provided the shaft speed is maintained.
