Excellent overload durability
The Models G 12SA2 and G 13SB2 provide excellent overload durability thanks to an improved cooling
mechanism and a high-power motor.
Practical test data: Comparison of torque when the stator coil temperature rise is 200˚ K

Prolonged service life of the carbon brushes
The service life of the carbon brushes is prolonged thanks to the adoption of the internally placed carbon
brushes and the improved winding specifications.
Practical test data: Comparison of service life of carbon brushes in the continuous rated load test
Wear resistance of armature coil
Both ends of the armature coil are sealed with heat-resistant adhesive in addition to varnish treatment to
minimize wear of the armature coil caused by dust.
