Refuse-collecting vehicles are significant polluters due to their expected drive cycles involving frequent stops and long idle periods. Electric refuse-collecting vehicles, still in infancy, promise address this through the replacement of internal combustion engines with batteries electric traction motors. Today, typical motors for these involve heavy use rare earth permanent magnets, which sub...

Rare-earth magnets which are the best solutions for PMSM rotors are expensive which makes that other types of motors are used in the applications. The solution of the replacement of these motors with PMSynRM that use low-cost type of ferrite magnets becomes more tempting lately. This paper proposes two different types of low-cost ferrite solutions: first a V permanent magnet assisted synchronou...

Switched Reluctance Motors (SRMs) are increasingly popular machines in electrical drives, whose performances are directly related to their operating conditions. Their dynamic characteristics vary as conditions change. Recently, several methods of the modeling of the magnetic saturation of SRMs have been proposed as analytical functions. However, the SRM system is nonlinear and cannot be adequat...

In industrial automation and robotic applications, direct-drive motors represent a suitable solution to friction and backlash problems typical of mechanical reduction gears. Variable reluctance (VR) motors are well suited for direct-drive implementation but, because of the strongly nonlinear electromechanical characteristics, these motors are traditionally designed as stepper motors. The main a...

This paper presents the design of a new axial-flux switched-reluctance motor (AFSRM) topology for in-wheel drive vehicle applications. The features of the topology include a short flux path and an outer-rotor configuration. The proposed topology also uses a sintered-lamellar soft magnetic composite core material, and permits displacement of the rotor along the suspension axis, which reduces dam...

Abstract— The Switched Reluctance Motor (SRM) drive has evolved as an alternative to conventional motors in variable speed drives because of advantages like simple and rugged structure, absence of rotor winding, adaptability to harsh environments and high speed operation. This paper presents the speed control of Asymmetrical converter fed 4 phase 8/6 Switched Reluctance Motor drive using PWM co...

Firmware version 4.8 allows Simotics synchronous reluctance motors to also be operated with Sinamics S120 converters, enabling them to benefit from the complex functionalities of the modular S120 product portfolio. The new Sinamics reluctance control license used in combination with the Sinamics Booksize Modules means that precise drive control down to a complete standstill is now possible with...
