There are many methods about efficiency measurement for introductive motors in international standards, among which the loss segregation method assumes that the stray loss and iron core loss can be treated as constants, and then the process of efficiency estimation can be simplified. This paper designed a motor efficiency measurement system based on loss segregation method. It’s a calculation module based on a micro-processor. The motor current is the only variable for motor efficiency calculation, this system can calculate and read the result on-line. The deviation between the loss segregation method and the direct method is very small. |
