Hi guys.
I'm building a dynomometer for a 1hp engine. I plan to use something like an alternator or a dc generator to do the braking. I will mount the alternator or generator so it is free to rotate around the shaft and measure the force at a distance to get the torque.
The idea is to vary the load on the alternator or generator to increase the amount of torque needed to turn it (therefore RPM will decrease), then use a data logger to plot torque vs RPM and thus calculate power.
My electrical knowledge is limited. Is it possible to configure an alternator or generator (capable of the same/more power of the tested engine) to work in this way? i.e. increasing the load on the alternator/generator to increase the torque required to turn it? If so, how exactly would it be wired?
