High power input and maximum power output
The Models PDA-100K and G 10SK3 are compact and lightweight, but powerful and offer higher power input
than the conventional Models PDA-100D and G 10SK thanks to the high-power motor. It is said that the
greater the maximum power output/weight is, the better performance the motor offers. Table 1 shows a
comparison of the motor performance. It is clear that the Models PDA-100K and G 10SK3 have higher
performance than the conventional Models PDA-100D and G 10SK respectively.

Durable motor
The Models PDA-100K and G 10SK3 are equipped with a motor whose durability is greater than the
conventional models by making the following improvements. The service life of the armature coil is 2 times
longer than the conventional models as a result of the gravel suction test (gravel is forcedly sucked in through
the vents of the tail cover).
The wedges at both ends of the armature coil are extended by 3 to 4.5 mm to protect the portions where
the peripheral speed is the fastest and apt to be disconnected by dust or gravel. Thanks to the application of
adhesive to the commutator hook, the hook has higher resistance to deformation or disconnection than the
conventional models when dust hits the hook.
New vent construction is adopted to prevent dust or gravel from getting inside.
