A dual mechanical port machine (DMPM) is used as an electrically variable transmission (EVT) in hybrid electric vehicle (HEV). In the conventional HEV, this machine is replaced by a planetary gearbox and two electric machines and makes this structure simpler. This paper presents field oriented control (FOC) for DMPM. For HEV application, drive efficiency and wide operating speed range are impor...

OBJECTIVE Analysis of mechanical measurements in laparoendoscopic single-site surgery (LESS) is important for instrument design and surgical simulators. The aim of this study was to develop a measuring system for different instruments and manipulations in LESS using a single-incision laparoscopic surgery (SILS) port. METHODS The loads on the SILS port were applied and recorded by the universa...

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 ...

Position sensorless control has been widely studied for electrical rotor position estimation. However, because of the magnetic periodicity, mechanical multipole electric machine was hardly reported. By increasing dimensions, this article proposes novel topologies named as dual-gap dual-pole composite machines, where can be demodulated from positions two air gaps. The and corresponding theory ar...

In this paper we describe a machine vision system for inspecting bearings, which are an important part of electro-mechanical kWh meters. The system consists of a personal computer with a frame grabber, a black and white progressive scan CCD camera, and a mechanical device with a stepper motor controlled by a special controller connected to the RS232 port of the personal computer. The quality of...
