Hello guys,
Just let me know if this is true that a dc motor with a pendulum on it's axle is an electrical equivalent of a parallel LC tank?
If so what it means? Can we use a motor-pendulum in a circuit instead of an LC tank?
Thanks
MrAl, I think he's talking about using a mechanical device in place of an LC tank, this couldn't be done iwth a spring/mass/damper system as there's no way to introduce the effect on the electrical system, the motor/pendulum interacts both electrically and physically however I might add that it's at a MUCH higher power level than you'd typically use an LC tank circuit at.
Yea, suppose you need to generate a very low oscillation (1 or 2 herz for instance) out of a Parallel LC circuit (in a royer oscillator for instance which an LC tank creates the oscillations of the circuit), Then using a motor pendulum is much reasonable than using an unreasonable massive inductor/capacitors, right?
