The detailed process of S3, if motor is operated under load L, when motor work normally, according to load-resistance curve, it is additional around
Standard electric resistance value of the group 23 at load L is R；During to the temperature monitoring of motor, controller constantly obtain it is additional around
The resistance value of group 23, and the resistance value is compared with standard electric resistance value R, comparison result is exported, if at a time, prison
The resistance value for measuring additional winding 23 is changed, and becomes R' from R, variable quantity is the absolute value of R' and R, if the variable quantity
Less than predetermined threshold value, then it is assumed that motor temperature is within normal range (NR), if the variable quantity exceeds predetermined threshold value, then it is assumed that motor is super
Go out normal working temperature range, illustrate that failure has occurred in motor, or illustrate that motor has the risk to break down, needs to close
Motor or the output power for reducing motor.
