Parameters identification of a brushless DC motor by specification

This paper describes approaches to the calculation of back-emf coefficient, torque constant and flux linkage. These parameters are necessary for the mathematical simulation of a brushless DC (BLDC) motor and are used as input parameters. The article gives an example of calculations for a 5 kW brushless DC motor HPM5000B. In addition, a verification method is proposed to check these parameters' validity through a library module Permanent Magnet Synchronous Machine.
