Design of stray loss test system for three-phase asynchronous motor
Asynchronous motor is widely used in every field and department of people's daily life and in industry and agriculture. Electricity consumption of asynchronous motor is the main asynchronous motor. Now the whole society is calling for energy-saving and environment-protection. It is important to improve AC motor's energy efficiency level for energy-saving, environment-protection and fund-saving. The manual computation of stray load loss in electric motor is very complex and has low precision so the stray load loss test system for three-phase asynchronous motor was designed. It discussed the application of linear regression analysis method in stray loss analysis in detail, and the computation was implemented by MATLAB, and a DLL was generated, last the VC program does data acquisition and calls the DLL to fulfill computation.
