I want to use universal motor as a DC generator. The motor specifications are
- 180 Watt
- 230 V
- 10000 rpm
When I supply the motor with 3000rpm it gives 1.5V. I thought it was rpm problem but when I supply 10000rpm it only gives 4V. While exploring its theory I figured out that a universal motor is a DC series motor. As for DC series generator there must be load connected to its terminals in order for field circuit to be energized otherwise the circuit will be open (if I am not wrong). But when I connect load (incandescent bulb of 100Watt and 220V) it give me even less than 1V. I do not understand what is the problem. If someone has good undestanding of universal motors please provide guidance.
