Abstract: In vector control system,the precision of rotor flux orientation speed estimation is relied on the precision of motor parameter.According to the steady-state equivalent circuit of the induction model,a new method to estimate parameter of motor which has been achieved,which uses own resources of the transducer.The mathod is concrete analyzed and experiment by VC system which based TMS320F2407.The experimental results indicates that this method is easy to realize,and it can offer quite accurate stator and rotor parameters for VC system.
