4-1. Class-top overload durability
The Models G 18SH2, G 18U2, G 23SF2 and G 23U2 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 23SF2 as the reference. As is evident from this, the Models
G 18SH2, G 18U2, G 23SF2 and G 23U2 are superior to the competitors in overload durability.
