A brush-less synchronous system includes a stator that generates a magnetic rotating field when originated by an alternating current. A peeling rotor disposed within the magnetic rotating field is separated from the stator to form an air gap relative to an axis of rotation. A stationary excitation core separated from the rotor disordered by an axial air gap and a radial air gap substantially encloses the stationary excitation core. Some brush-less, permanent brush-less synchronous systems include stator core voids to reduce axial flow. Some brush-less, permanent brush-less synchronous systems include a clear rotor coupled to exterior laminations. Quadrature axis inductance can be increased in some synchronous systems. Some synchronous systems convert energy such as mechanical energy into electrical energy (eg, a generator); Other synchronous systems can convert any form of energy into mechanical energy (for example, a motor).
Nidec Corporation has announced that the Nidec Research and Development Centre has developed a motor drive system based on a silicon carbide (SiC) inverter. The Nidec Research and Development Centre has been able to manufacture the world's first conceptual model of a drive system using a magnet-less motor with a SiC based inverter by applying the prior drive technology to a switched reluctance (SR) motor from Permanent magnets but requires special control. The future drive system must be compact, light and efficient. Low energy consumption is the most important challenge, as power consumption by motorised equipment accounts for 57.3 percent of total energy consumption in Japan. Power semiconductors such as SiC and Gallium Nitride (GaN) have been developed, and Nidec Research and Development Centre has applied them to a compact and lightweight motor drive system, focusing on SiC semiconductors, which offer reduced power losses , Improved heat resistance and increased current capacity. The volume and weight of the above concept model are 32 and 69 percent of the conventional engine drive system, including the engine and the inverter, respectively.
The design of the drive system requires electrical circuit technology and thermal analysis technology to facilitate the thermal management of inverter circuit components. Kyoto University has carried out decades of research and development of SiC power semiconductor devices. The SiC power semiconductors that were used by the Nidec Research and Development Centre were developed through the participation of Nidec in the Kyoto super combustion program of the Japan Science and Technology Agency. Many other universities, corporations and public research organisations participated in the development. One of the central institutions of the Kyoto super combustion program is the Institute of Advanced Scientific and Technological Research of Kyoto.
Specifically, the Nidec Research and Development Centre has made open innovation through the joint collaboration with ROHM, located in Ukyo-ku, Kyoto city; Nichicon, located in Nakagyo-ku, Kyoto city; And Kyoto University, Osaka University and Ritsumeikan University. The Nidec Research and Development Center has also conducted a joint research with Yokohama National University on thermal analysis technology for motor drive systems, including simulation of SiC-based inverter circuits. The Nidec Research and Development Center of Nidec Corporation has already developed a motor drive system using a SiC based inverter. An integrated motor drive system (in which the inverter is built into the motor housing) will be developed in 2015. * Source: "The research report on the current and future trend of energy consumption of electric instruments" By the Research and Development Association for the Future Electron Devices issued on March 23, 2009.
