A hybrid alternator has a rotor with a plurality of permanent magnets disposed between opposing claw-pole segment pole fingers. The magnets are radially retained by the pole fingers during rotation. The magnets are supported during high speed rotation characterized by outward flexure of the pole fingers at surfaces inboard of extreme ends of the magnets thereby reducing load stresses on the magnet.

Rotor for hybrid generator having improved magnet retention

An alternator has a rotor with a plurality of permanent magnets disposed between opposing claw pole members and a field coil. The plurality of permanent magnets are secured to at least one ring-shaped carrier which surrounds the field coil and locates the magnets into appropriate positions between the fingers of the claw pole members.

Rotor assembly for hybrid alternator

An improvement is provided for an electrically heated glass panel of the type where a resistive film is disposed on the panel and is connected between and along the length of a pair of spaced bus bars each of which is terminated in a respective voltage input terminal and where one of the bus bars includes a connector section to which the resistive film is not connected extending from the input terminal of the bus bar to a junction point on the bus bar beyond which the resistive film is connected to the bus bar. A sensor conductor is disposed on the glass panel and connected from at or beyond the junction point on the one bus bar to a sensor terminal and extends generally adjacent to the connector section of the bus bar. Prior to applying a high voltage across the input terminals of the bus bars to energize the resistive film when it is desired to heat the glass panel, a low voltage incapable of producing an arc across any break in the connector section of the one bus bar is applied to the input terminal of such bus bar. The power supply is disabled in response to the presence of a predetermined voltage difference between the sensor terminal and the input terminal of the one bus bar indicating the presence of a break in the connector section of the bus bar so as to prevent the development of an arc across the break.
