BRUSH REMAIN-%
Brush Remain-%
Only for DC motors
The DC motor brush life is estimated according to the following
formula:
Estimated_Life = Expected_Life * Nominal_Power / Current_Power
To indicate the remaining life, the following formula is calculated
once per second:
Brush_Remain = Brush_Remain - [(100/(3600*5000))*(MotorPower
/ Nominal_Power)]
Where: 100 indicates in percent
(3600 * 5000) expected life in seconds
(Motor_Power / Nominal_Power) The current power ratio, limited to
0.1
If the motor is new, one should enter 100% in <BRUSH REMAIN>
Also after checking the brushes, the parameter can be modified on
the basic of current brush life.
