I tried to get the parameters for a bldc simulation https://de.mathworks.com/help/physmod/sps/ref/brushlessdcmotor.html

I tried to find a similar motor to the I need (500 W, 20-25 Nm, geared bldc) However I can't get either flux linkage or the rotor-induced back emf, the options there.

Could you help me how can I get the data needed from a table like this? https://www.semanticscholar.org/paper/Mathematical-Modeling-of-Permanent-Magnet-Brushless-Shetty-Subramonium/7bd32a8ef2049ede79ef2eb6af7609d4ca5701dd/figure/0 table1

Any help or literature is appreciated.

  • I'm quite new to stack exchange, is there something I can do to improve my question? – Hegedus.Cs Oct 09 '18 at 18:39
  • how to improve the question? unsure at the moment... what can be done is a bit of patience. less than 14minutes before querying a response is a bit... we are volunteer's of a small stackexchange –  Oct 09 '18 at 18:54
  • So far I found this link https://electronics.stackexchange.com/questions/110557/calculating-back-emf-from-torque-constant It seems assuming blcd with trapezoidal back-emf toque constant is less than or equals with the back-emf constant According to this link https://www.motioncontroltips.com/faq-difference-between-torque-back-emf-motor-constant/ Emf = emf constant * angular velocity Could someone confirm my understanding? – Hegedus.Cs Oct 09 '18 at 19:16
