Considering negligible T
load
value for constant torque applications, the resulting minimum deceleration value will
be:
decTime > ( 5 * 157.08 * 110 ) / ( 6400 ) = 13.5 s
Nota! The braking action of the applied load and friction can contribute to reduce the minimum time of deceleration. This further reduc-
tion depends on the characteristics of the load. For variable torque application, the reduction could be substantial. Contact Gefran
for application support.
