This is a comprehensive simulator written to simulate a trapeziodal back emf, star wound brushless dc motor. Complete flexibility in varying various model parameters have been provided. This is the result of the undergraduate project taken at National Institute of Technology Karnataka (INDIA) with a team of Mr Jora Gonda, Raghunandan SN and Manas Bhat.
About 25 different simulation variable can bve monitored. This is intended to be a freeware so that with time the product can improve.
The approach used has been to avoid the use of Simpower (power electronics) block set which demand huge processing power and memory. The core BLDC module 'mybldc' is logical and the inverter has been made out of logical elements resulting in a faster simulation.
Hi Devendra, thank you for putting together this model it has been extremely helpful for me. I however have a few questions 1) I dont't have stste flow toolbox so I built my own but following the logic that you presented in your document. 2) I disables all the zero crossings to avoid errorr. 3) I don't seem to get the control of the signal the speed remains oscillating around zero rather than following the commanded speed. Have you experience this before? I am usign 0de113 and also have tried changing the PID constants but with no success. I would appreciate very much your reply.

Could some one can tell me whats the diference between that and the earlier version?

What changes will be observed when three phase six step star connected two pole pair BLDC motor is used Pl also suggest about electonic commutation sequence for the same
