Abstract: Proposed an improved induction motor off-line parameter identification scheme for vector controlled AC motor drives.The inverter drives automatically performed the DC test,the single-phase test,and the no-load test to calculate all the machine parameters during self-commissioning period.The proposed scheme can eliminate the parameter identification error due to the skin and dead-time effects.Introduced the scheme principle and the implement method in detail.Experimental results demonstrated the feasibility of the parameter identification method in 11 kW vector controlled induction motor drive system.
