1.1 This specification covers wrought carbon steel sleeve type pipe couplings suitable for joining carbon steel pipes.

1.2 Type I couplings are intended for use on all schedules of pipe where the pipe wall thickness does not exceed the wall thickness of standard weight pipe. Type II coupl...

A novel structure of axial flux stator and rotor dual PMs Vernier machine is presented as an effective option for high torque-density direct-driven applications. The key is to locate PMs on both sides of rotor and stator. With dual PMs, this proposed machine with a novel structure generates an impro...

In this paper, the case of a battery charger for electric vehicles based on a wireless power transmission is addressed. The specificity of every stage of the overall system is presented. Based on calculated and measured results, relevant capacitive compensations of the transformer and models are sug...

Indirect field oriented control (IFOC) has become a widely adopted solution for AC motor drives. Standard IFOC controls torque and rotor flux linkage via q- and d-axis current. Alternatively, deadbeat-direct torque and flux control (DB-DTFC) has emerged as a promising motor control strategy for the ...

The utilization of position sensor reduces the system reliability of switched reluctance motor (SRM), especially in harsh environments. It also increases the complexity of the system. Therefore, the research on sensorless control has become one of the hot spots in recent years. Comparing with the ex...
