Designing and performance investigation of permanent magnet motor prototype for UTV electric drive train application

Abstract

<span lang="EN-US">The dynamic design specifications of a vehicle are used to define the required torque and speed of a permanent magnet motor. This is due to providing clear instructions on the intent, performance, and construction of a vehicle. Therefore, this study aims to determine an engineering design and prototyping process of a Permanent Magnet Motor, to be used as an electric powertrain in a Utility Vehicle. Based on being used in severe road condition (steep inclination and off road), the vehicle should be able to handle a 45° inclination with total payload of approximately 250 kg. Using a rear-wheel-drive traction, its weight should also be less than 1000 kg. Furthermore, the motor should be operated at a maximum battery voltage of 100 V. According to the requirements, the electric powertrain should further have the ability to deliver a torque of approximately 1600 Nm on both rear wheels. Using a finite element method to simulate performances, transmission was coupled to the motor in providing the required torque. In addition, the motor prototype was subsequently manufactured and tested using a dynamometer. The results showed that the motor produced 19.6 kW, 5600 RPM, and 75 Nm at 96 V. Therefore, the design and prototyping process of the motor satisfied all the required specification.</span>

On the Development and Experimental Validation of a Novel and Intuitive Interior Permanent Magnet Synchronous Motor Controller for Electric Vehicle Application

“…The proposed controller in this paper was implemented in an off-road vehicle [21]. It has a two speed gearbox with ratios of 1:32 and 1:16.…”

“…The permanent magnet synchronous motor (PMSM) investigated is the 3-phase interior mounted permanent magnet motor presented in Figure 1. It was developed by the authors of [21] in 2021 to be used in an electric utility vehicle. According to Figure 1, the PMSM has three phases and a V-shaped interior permanent magnet synchronous motor (IPMSM) with the specifications tabulated in Table 1.…”

Optical spectroscopy as a tool for studying the solution chemistry of neodymium(iii)

“…26,63–66 In the global effort of transitioning the energy infrastructure into green, renewable solutions neodymium holds an important role, 67–70 and as the demand for strong, permanent magnets used in wind turbines and in drive trains for electric cars increase, so does the demand for neodymium. 39–41…”

“…Terbium(III) and europium(III) may be easier to study using luminescence, 18,[31][32][33][34] and the electronic structure of ytterbium(III) may be simpler. [35][36][37] But neodymium(III) that is at the heart of both wind turbines and electric drive trains, is probably the trivalent lanthanide ion of greatest relevance, [38][39][40][41] and that is why this element is the focus of this review. Further, and in contrast to the bulk of the work on terbium(III) and europium(III), [42][43][44][45][46] the study of neodymium(III) in solution can rely on both absorption spectroscopy and luminescence spectra.…”
