4-1-2. Improved overload durability (improved cooling efficiency)
The Models DV 18DMR and DV 14DMR are equipped with the separate-type motor. To improve the overload
durability in continuous operation, the optimally designed cooling air path that is descended from the Model
DS 12DM increases the cooling efficiency as well as the large radial fan increases the volume of air (See Fig. 1).
