After measuring the motor speed with a tachometer, calculate the car running speed according to formula (1):
Wuzhong Ur--
t·D·n
1000 . 60 . i - z2
-Car running speed, m/s:
D-—Traction sheave pitch diameter, mm;
n*actual motor speed, r/min;
i}-——Traction machine reduction ratio;
i-—traction ratio.
The deviation value is calculated according to formula (2):
Running speed-rated speed×100% (2) Deviation value—this
rated speed
The car running speed can also be obtained by measuring the electric rope linear speed with a speed measuring device.
