General

I need to model a brushless motor for which I only have the data of voltage, power, speed, nominal torque, starting torque, max current and total weight, which moves a bicycle. I have studied the Permanent Magnet Synchronous Machine power_pmmotor Simulink example, but I do not have all the required data. My question is whether it is possible to make an approximate model with my few data. I guess some data could be assumed, but I don't know what typical values ​​would be correct. I would greatly appreciate any suggestion. My best regards.
