摘要： Unique systems, methods, techniques and apparatuses of an exciterless synchronous machine are disclosed. One exemplary embodiment is a salient pole rotor for an electric machine comprising one set of pole pairs including a first, second, and third pole pair; a field winding; a set of energy harvest windings, each winding mounted to each of the plurality of pole pairs and structured to receive a harmonic component of AC power from a stator; and a DC power supply structured to receive the harmonic component from the set of energy harvest windings, convert the harmonic component to DC power, and output the DC power to the field winding. The set of energy harvest windings are arranged in a first sequence on the first pole pair, a second sequence on the second pole pair, and a third sequence on the third pole pair, and each sequence is different.

摘要： A drive system is provided for propelling a ship through water. The drive system has two propellers. The propellers are coaxial so that one propeller engages the incoming water first, and the other propeller engages the water after it passes through the first propeller. The drive system has a stator that causes a first rotor to rotate. The first rotor is connected to, the first propeller to cause the first propeller to rotate. The first rotor also causes a second rotor to rotate. The second rotor is connected to the second propeller to cause the second propeller to rotate.

摘要： An assembly that can enhance the power factor of synchronous reluctance (SynRel) machines. The assembly can include one or more pickup coils that are at least proximally adjacent to an outer periphery of a rotor that are structured to harvest energy in an air gap between the rotor and a stator. The harvested energy can be supplied to a rectifier that is electrically coupled to the pickup coils, and which can convert the harvested energy into DC excitation current. The DC excitation current can be provided to one or more DC field windings that extend through the rotor, such as, for example, through flux barriers in the rotor. The flow of the DC excitation current through the DC field windings can generate a flux that can be put in a rotor axis to enhance the power factor and torque rating of the SynRel machine.

摘要： A permanent magnet motor is provided that produces variable magnetic flux. The motor may include two different types of permanent magnets with different coercivities. The magnetic state of one of the magnets may be altered during use. In one state, the effective magnetic flux of the motor is greater, and in another state, the effective magnetic flux of the motor is less.
