Abstract
An alternator with a longer stationary coil support or bobbin and rotor axial and components thereof are provided.
Claims14
A claw type, brushless alternator comprising:
- a drive end frame having a stationary coil assembly mounted thereto;
- the stationary coil assembly comprising a hollow bobbin and stationary coil wound thereon;
- a stator circumscribing the stationary coil assembly such that a gap is provided between the stationary coil assembly and the stator;
- a rotor assembly having a rotor shaft with pair of opposing claw type poles mounted thereon;
- wherein each claw type pole has a plurality of fingers;
- wherein upon installation into the alternator, the rotor shaft is mounted through the hollow bobbin and the plurality of fingers are sandwiched between the stationary coil assembly and the stator.
3 more elements
A bobbin assembly for use in a claw type, brushless alternator, the brushless alternator having a drive end frame and drive end bearing, the bobbin assembly comprising:
- a hollow bobbin with lips at each end of the hollow bobbin and defining a coil winding surface;
- and
- a stationary coil wound on the hollow bobbin;
- wherein one lip of the bobbin is configured for direct mounting to the drive end frame of the alternator and comprises a surface to support the drive end bearing.
1 more element
A bobbin for use in a claw type, brushless alternator, the brushless alternator having a drive end frame and drive end bearing, the bobbin comprising:
- a hollow cylinder with lips at each end of the hollow cylinder and defining a coil winding surface;
- wherein one lip of the bobbin is configured for direct mounting to the drive end frame of the alternator and comprises a surface to support the drive end bearing.
