4-1. Class-top Overload Durability

The Models G 18SE3, G 18UA2, G 23SC3, G 23UA2, G 18SG2, G 18UB2, G 23SE2 and G 23UB2 provide

excellent overload durability thanks to the improved motor winding and carbon brush material in common with the

current models (the service life of the carbon brushes is also prolonged). Figure 1 shows the comparison of

overload durability when the stator coil temperature rise is 200˚K using the Model G 23SC3 as the reference.

As is evident from this, the Models G 18SE3, G 18UA2, G 23SC3, G 23UA2, G 18SG2, G 18UB2, G 23SE2 and

G 23UB2 are superior to the competitors in overload durability.
