This paper presents a novel hybrid human-machine interface (HMI) designed for hands-free control of electric powered wheelchairs. Both forehead electromyography (EMG) signals and colour face image information are deployed to identify winking and jaw clenching movements of human face. Five winking and jaw clenching movement patterns are selected and classified, mapping into six control commands ...

Abstract: The proposed method allows determining the level of wear of the bearings of electric machines by means of rotor radial displacement during operation. Measurement is effected by non-contact method and optoelectronic sensor which converts the rotor mechanical motion into electric signal. Received informational signal is recorded and processed by computer system. Based on the processed i...

The market for power semiconductor modules is spreading not only to general-purpose inverters, servo motor drives, NC machine tools and elevators but also to new applications through the realization of electric vehicles and renewable energy systems. Fuji Electric has developed various power modules in response to market needs, and as the market expands in the future, the required performance fo...

A new dual-mechanical-port (DMP) electric machine for hybrid vehicle applications, particularly in the power-split continuously variable transmission systems, is proposed this paper. In order to comprehensively and quantitatively evaluate pros cons of machine, a comparative study four DMP machines with different topologies conducted. These investigated include conventional spoke-type permanent ...

Accurate computing of the saturated inductances of Permanent Magnet Synchronous Machine (PMSM) is very important during the design process. In this paper, a new method is presented based on the B-H characteristic of the stator material and unsaturated inductances formulations. This method is used to calculate the saturated inductances of the axial flux PMSM. The synchronous inductance and all o...

Fast and accurate transient response is the main requirement in electric machine position control. Conventional cascade control structure has sluggish response due to the limitation of inner control loop bandwidth. In this paper, in order to decrease the Permanent Magnet Synchronous Motor (PMSM) transient response time it can be used reference model using feed-forward signals. In this structure...

This paper proposes a novel multi-phase single-turn permanent magnet synchronous motor (MSPMSM) to meet the stringent requirements of electric aircraft, such as high power density, torque, and low mass volume. The MSPMSM features unique winding configuration, which can reduce coil overhang, increase density weight in conventional multi-turn motors. proposed is studied by finite element method (...
