Application Data
Generator Features
D Brushless, rotating field design permits power to be
obtained from stationary leads.
D Rotor and stator are vacuum impregnated and coated with
high-bond epoxy varnish. Varnish helps prevent corrosion
in high-humidity areas.
D Rotors are dynamically balanced to minimize vibration.
D Copper windings ensure minimal heat buildup. Insulation
meets NEMA standards for class F insulation.
D Direct connected to the engine, the generator has sealed
precision ball bearings with a precision-machined steel
sleeve in the end bracket to prevent shaft misalignment and
extend bearing life.
D The generator is mounted on a dripproof tray.
D The generator is equipped with a four-lead reconnectable
stator.
