Abstract: The problem of effectively and quickly detecting fault conditions in an electromotive machine (10) is solved using a current transformer assembly (28) having a neutral lead (44). The neutral lead (44) comprises a single piece copper strap (80) having laterally extending strips or posts (81-83) provided for connection to the neutral end conductors (31-33) of armature windings (22 and 24). The strap (80) is punched and bent into shape to include the three neutral posts (81-83). Each neutral post (81-83) carries a current transformer (46-48).

Abstract: A power conversion apparatus includes a first electrical machine (140) and a second electrical machine (160). The first electrical machine includes a first rotor portion (142) and a first stator portion (144) electromagnetically coupled to the first rotor portion (142). The second electrical machine (160) includes a second rotor portion (162) and a second stator portion (164) electromagnetically coupled to the second rotor portion (162). The first rotor portion (142) is connected to the second rotor portion (162) at shared axial position for common rotation therewith about a rotational axis of the power conversion apparatus.

Abstract: An electric power system (EPS) (100) may comprise a permanent magnet synchronous generator (PMSG) (120), a high speed rectifier (140) configured to receive a first alternating current (AC) power from the PMSG (120), and a low speed rectifier (130) configured to receive a second AC power from the PMSG (120). The low speed rectifier (130) may be configured to receive the first AC power in response to the PMSG (120) rotating at a first rotational speed, and the high speed rectifier (140) may be configured to receive the second AC power in response to the PMSG (120) rotating at a second faster rotational speed.

Abstract: A machine includes a rotor and a stator 200 disposed about an axis. The stator includes a ring disposed about the axis. A plurality of poles 202 each extend radially from the ring and support a coil of a wire 204. Moldings 206 insulate at least a portion of the plurality of poles from the wire. The moldings include a radially outer portion, a radially inner portion, a connector portion integral with the radially outer portion and the radially inner portion, and a tab 224 on one of the radially outer portion and the radially inner portion. The wire is wrapped behind the tab between adjacent poles. A method of insulating and securing wire for coils formed on adjacent poles is also disclosed.
