  uh is this more true for teslas with their non magnet motors? around town in my volt with master race rare earth magnets i regularly get 5-7 miles/kwh. feels like i dont have all these efficeincys and fet switching trickery, its just a magnet spinning...

  Thanks for making these videos, they are quite informative 👍 One Question: Torque is produced by the force generated by the interaction of Magnet's Magnetic feild & current flowing through the Copper wires (I.B.L.Sin(theta), Amperes Law). Back EMF is produced due to rate of change in Flux from PM of Rotor. how does the energy associated with I.BEMF equals the energy produced ?

• 
  @jtlee11082 ай бұрын

  In an idealized motor (ignoring losses, and idealizing commutation) back EMF times current flow will equal the torque produced times the velocity

  If I had watched this video before my interview, I could have probably cracked it. The current flow direction, magnetic field direction and torque direction you explained at the start could’ve saved me. :)

  Why do we need to use V0 and V7 what happens if i remove them. Line must be V1 - V2 - V1 - V2 - V3 - V4 - ....... And i wanna say, that's a great explanation sir, thanks for your video

• 
  @felipedamascenosilva30112 ай бұрын

  The idea behind V0 and V7 is that you can control the magnitude of your SV current/voltage instead of only controlling its angle. You achieve so by litteraly turning the IGBT bridge off from time to time, rather then always working on full capability. If you remove them, you lose the ability to smoothly turn on and turn off your motor in a ramp shaped form, for example.

• 
  @felipedamascenosilva30112 ай бұрын

  Actually, after reinspecting the equations on 8:33, I saw that, even on full work (DC = 1), you still have T0 different from 0. That should be to avoid "escaping" the unit circle, since the true range of that SV basis is an hexagon, not a circle. I belive that, if you're already in stead state and want to overperform, maybe you can overmodulate by dropping V0/V7, but I can't say that for sure.

  What does the number of pole pairs mean? I suppose it correspond to the number of windings divided by 3. But at the same time people speak about the number of the rotor poles. Some times we may have 12 windings and 10 poes in rotor. So, how many pairs of poles do we have there? 12/3 = 4 or 10/2 = 5?

  i'm just a little confused, it's about the direction of the current. If i put the phase A to +VCC, phase B and C to gnd, the current will flow from A to B and C. At this moment, the alpha current will be equal to (-|iA|) or (|iA|)?🤔

  Is there a way to run bldc motor without hall sensor.

• 
  @jtlee110810 ай бұрын

  Yes, several actually. Generally SVM doesn’t use halls, you either use an encoder with much higher resolution than halls (if you are doing some sort of feed back torque control), or you can run it in feed forward or using back emf as your angle estimation (obviously this requires slightly higher speeds)
