Oh so that's where I was going wrong. I was trying to take the rpm and calculate torque rather than setting my torque and rpm then calculating power.
The method you described makes sense. Just to verify something though,
Say my motor has a 80mOhm resistance (most bldc have around this) then...
6700rpm is the needed speed yes (to turn a wheel of 120mm fast enough to give the required forward speed)
I cannot find a rated voltage/rpm/torque of the motor as it is a brushless DC motor. ie I get given a Kv value and a max power.
Say for arguments sake I have a 'magic' power supply that...
Perhaps to help you out research the LHC. This is a large multi-national project that had a budget of 7.5 billion euros. Took many many years to build with large numbers of engineers. Now you probably won't want to go that big but to accelerate anything it usually needs to be small (more mass =...
So I need a motor that is able to provide \begin{equation}0.412Nm\end{equation} of continuous torque (to overcome rolling resistance).
A BLDC I have is rated at \begin{equation}285W\end{equation} and 4700Kv (rpm/V).
So I was wondering if my calculations are correct.
Using the...
Yes however, normally I use the Laplace form of the equation to make the transfer function to then recreate the Bode Plot.
The problem is that the Laplace transform is
sV_i = A s^2 V_o + B
As you can see the Constant B makes creating the transfer function very difficult!
I have attached a picture of the circuit in which I am attempting to build a transfer function for, however, as you can see it is not a normal integrator. Normally it is evident which resistor is the resistor that is part of the series connection to the op amp.
When I do the KVL on the...
My question is a relatively short one. Simply put it is:
"Will an electron oscillating in a vacuum lose energy?"
My thought comes from does the presence of the moving charge create electromagnetic fields. I have no idea how you could get the charge to oscillate but perhaps in the neutral...
I know that positrons are produced by beta + decay and I know that they are antimatter. My question now comes to what happens when the collide. I know that should be complete annihiliation and the most likely outcome is the production of two or more gamma rays. My question comes when trying...
