Abstract: In order to restrain the influences of higher harmonic of the variable frequency source to variable fre
quency and speed regulation asynchronous motor, Op timal ic design method of variable frequency and
speed regulation asynchronous motor, such as op timal stator and rotor slot matching, op timal design of rotor slot type
and airgap, constructing variable frequency and speed regulation motor fuzzy self adap tive design model are p resen
ted. U sed the V isualBasic 6. 0 as a tool, the op timal ic design software of variable frequency and speed
regulation asynchronous motor is developed to imp rove p racticability of p rior design software. The 11 kW inverter
driven asynchronous mot
