Multi-three-phase motor drives are experiencing a significant development among the multiphase solutions since they are configured as multiple three-phase units operating in parallel. Although the literature reports several torque controllers able to deal with multi-three-phase motors, most of them obtain high performance of torque regulation as lo...
Multi-three-phase motor drives are experiencing increasing industrial development as these multiphase motors can be configured as multiple three-phase units operating in parallel. In this scenario, the literature reports several torque controllers for multi-three-phase motors to guarantee high performance in torque regulation accuracy and efficienc...
The accurate magnetic model is mandatory for high-performance control of high anisotropy synchronous machines. This paper presents a time-efficient and accurate magnetic model identification based on triangle current injection while the machine under the test is driven at a constant speed by a prime mover. The current injection pattern allows scann...
This paper proposes a new magnetic model self-identification technique for synchronous machines to build the flux-map look-up tables (LUTs). Provided the shaft is free to turn, an alternating self-acceleration and deceleration sequence is envisaged for identification without a dedicated experimental rig or additional hardware. Respect to previous w...
Permanent magnet assisted synchronous reluctance (PM-SyR) motors often present relevant magnetic saturation, especially if overload capability is exploited. The knowledge of current-to-flux relationship is mandatory for proper motor control, and it becomes even more critical in the case of sensorless applications. Reliable standstill self-commissio...
