METHOD FOR CORRECTING TORQUE FOR SUBSTITUTING PERMANENT-SPLIT CAPACITOR MOTOR BY ELECTRONICALLY-COMMUTATED MOTOR

摘要

A method for automatically correcting torqueincluding:presetting rotationalspeed of eachgear by corresponding gear input lines of a microprocessor; providing acertainmechanism to select one rotational speed set; electing N power pointswithin arange ofthe rated power, acquiring a set of torque datacorresponding to each set ofthe rotationalspeed at each power point, and storing a total 2xN sets of torque data;allowing the motorto enter the torque correction mode;recording a steady torque Tadj when themotoroperates in a steady state;and comparing the steady torque Tadj with a maximumgeartorque Tmax,and selecting the set of torque data to which T[M]max belongs whenthesteady torque Tadj satisfies the relationship: 110% x T[M-l]max Tadj=110% xT[M]max, M=1, 2, ..., N; when M=1, T0max=0.
