EV fundamentals #1: How to read a resolver 

Good idea sir, please continue this series with explaining how the code and hardware works.

Thanks for the video. Great idea for this series. Gives us a better understanding of what's going on.

Great video, gives a lot of useful information! Keep them coming :)

Very nice video Johan, just keep 'em coming (from one of the nerds)

Great explanation Johannes. Please keep going to make videos just like this:)

Literally exciting topic :)

This is really good! Thanks!

Thank you so mutch for these videos.

From my medical equipment repair days, I have come across resolvers that the reference coil is on the stator and the readout is done on the rotor ( they can definitely afford the space there ). Nice stuff indeed, not many people know of them nowadays ( most motor control will actually be done with encoders with an index pulse given from somewhere in the system ).

Super stuff Johannes

This was an awesome video

This is some wicked smart shit! I don't understand any of it, but respect those that do, ha ha

Great learing module sir thank you...

what is the library that you are using for stm programming ? Thank you.

Thanks for the video.Let mi suggest a topic : An electrical axis. An master encoder, a slave encoder and an output that control a motor+slave encoder that follow to master encoder in velocity and phase with a low margin de error (< 5 degrees so and so). Thanks Johannes

I hated working with Resolver that encoder ,this video changes my attitude

Superb video. Thanks for the in depth walk through!! Looking for more in this series. Btw, just a basic question: why are there many coils when there are 2 output signals and 1 input? Are they connected on parallel?

Hi, Thanks for the video. I will be trying to replicate this resolver on TI MCU.

I really liked this. When the leaf inverter chip is released could you make a tutorial for that as well?

Can i conect a synchro of 400 hz to 60 hz????

Hello! Is this board "Main board V3" capable of handling prius gen 2 inverter coupled with any toyota PMSM motor with resolver? Thank you!

If we set 7 volts in the primary coil, what will be the peak voltage in the cosine coil at angle zero Is it 7 volts or less? The rule to find out the peak voltage at angle zero is as follows (peak potential of the cosine signal = voltage on the input coil x cosine of angle sita) (V cosine=Vr x cos cita)

Johannes, could you please share winding schemes of resolver, and drawings or sizes of stator and rotor ? as I remember rhis type of resolver (with this type of rotor) named Verner ?

Thank you for this excellent and informative video, Johannes. Please would you consider expanding the code to handle synchro resolvers which have three secondary windings connected in a Y configuration? Otherwise, it is necessary to convert the 3 phase synchro signal to a 2 phase resolver using a Scott-T transformer (difficult) or equivalent solid state converter. Thank you again 👍

Is there a way to determine the resolver pole pairs count?

Functional safety involves correct component selection, electronics/system design, as well as software development. Safety doesn't seem to be covered in any of your videos or inverter designs, which is worrying because an incorrect torque could cause a serious accident.

I see no mention of functional safety. Have you at least tried to meet any safety standards, and if so, which ones and how?

The fan noise in your office is quite intrusive. A lapel mic should avoid this.
