📚Syllabus
• Investigate the operation of a simple DC motor to analyse:
- the functions of its components
- production of a torque 𝜏=𝑛𝐼𝐴_⊥ 𝐵=𝑛𝐼𝐴𝐵sin𝜃
- effects of back emf (ACSPH108)

This was the missing piece for me when understanding KVs and how it changes with current and torque in RC motors. Thanks for the video, keep up the good work!

[@user-im1uy8vu4j]

thank you so much your explanations is very easy to understand

[@hsuan-jenhankwang2448]

Thank you for your video this really help me a lot.

[@GoogleUser-ee8ro]

very clearly explained

Wdym by 'opposing force' - it's the first time i hear something like this, how can a system apply a force onto itself?
