Electrification of hydraulic systems using highefficiency permament magnet motors

Palavicino, Pablo Castro, Sarlioglu, Bulent, Bobba, Dheeraj, Lee, Woongkul, Minav, Tatiana 25 June 2020 (has links)
In this paper, electrification of hydraulic systems is proposed using high-efficiency permanent magnet (PM) motors and wide bandgap power electronic drives. Direct driven hydraulics (DDH) is selected because of its higher efficiency compared to other conventional technologies such as valve-controlled systems. The DDH is directly driven by a servomotor. The ratings and design guidelines for a servomotor used in DDH applications are provided in this paper. Specifically, a surface permanent magnet synchronous machine (SPMSM) is designed. Finally, a state-of-the-art inverter using silicon carbide wide bandgap devices are designed for high performance operation.
