2022.01.22 01:34 MoreSquare Coil Driver Operation
I think this is the easiest way to describe the coil driver - let's say I have an inverter rated for 100 Amps/phase.
Series mode, I have 3 sets of 2 coils in series. Each coil in each set will get a peak of 100 Amps Parallel mode, I have 3 sets of 2 coils in parallel. Each coil in each set will get a peak of 25 Amps Magnetisim is proportional to the intensity of current, so a higher magnetism will be achieved with 100 Amps in each coil than 25 Amps. Higher magnetism means more torque.
There is a total of 100 Amps running in both cases, but series has much more torque. Why can't series run as fast as parallel? Because of the time element.
Inductors => V = L di/dt, and when the inductance is in series, L is higher than in parallel. But we know V is relatively fixed, because the inverter runs off of battery voltage. di/dt (rate of change in current) translates to the speed of the motor and how fast current can be developed. As the motor speeds up, you need a faster change in current to (synchronize with the rotation speed and to get the intensity of current required to induce magenetic force [torque]). So to get the higher speed with a fixed V, you need to reduce L to get faster current changes, and to do that you put the coils in parallel instead of series, reducing L in the equation.
V = L * rate of change of current. V is fixed. For qucker changes, reduce L. Reduce L by going into parallel mode. Higher rate of change allows for larger magnitudes of current at higher speeds. This allows for more torque.
Series mode is important because the inverter is current limited. You would need 400 amps to get the same level of magnetism at the low speed (if 100 to 25 is correct).
I'm not sure how this affects the wire size in coil construction. I'm also not sure about magnetic saturation. Also note i'm not confident of the 100/25 amp ratio. maybe it's 50/25, because the coils can only magnetize so much (AKA coils saturate at 50 Amps not 100 Amps).

2022.01.22 01:34 oceanmanbuthere I know what I said BUT
I don’t like losing 2 queens in a split premiere, effectively having 2 first boots.
However, eliminating them just to bring them back for no reason is so dumb and like ??? I hate it so lame

2022.01.22 01:34 Word-Consistent DFS Resolution
Today me and my guildies (groups of two) that are over 700gs have been going to elvia spots and asking people if they accept DFS, if they said yes we would proceed to feed them to mobs. If they said NO we would just move on and leave them alone.
Today we have succesfully feed 8 people to mobs.
We will be continuing this activity for as long as its fun on Saturdays and Sundays or until this DFS non-sense stops :)
We are from the EU server and we urge others to join in this community-made fun, feel free to organize your own groups on NA.

2022.01.22 01:34 Gr33bster Kogan TV issues
My kogan TV that is under a year old will randomly lose its picture while on and after a restart it will switch between picture and no sound or sound and no picture. If we are lucky it will work again fine after awhile.
It's still under warranty so can be sent back but if it's an easy fix like software related no point in doing it.
Model of tv-KOGAN 50" 4K UHD HDR LED SMART TV ANDROID TV™ (SERIES 9, XU9220)
Thanks in advance
