Ambitious electric motor goal from USA

QM Power and the SPARK Lab at University of Kentucky shared the combined results of a large-scale, multi-objective design optimization study, and lab testing of a prototype motor designed to meet the ambitious 2025 power density goals set by the US Department of Energy (DOE). The research demonstrated the high torque and speed capability of QM Power’s innovative permanent magnet motor technology. This, combined with advanced manufacturing and cooling technologies, achieved a record-high 50kW/liter volumetric power density for traction applications such as electric vehicles (EV).
The computational study was conducted at the SPARK Lab and an open frame lab prototype was designed and manufactured by QM Power. Tests and extensive simulations were conducted at University of North Carolina, Charlotte and at University of Kentucky to reveal the best outcome given trade-offs among efficiency, power density and power factor while achieving the DOE 2025 target. In 2019 the US DOE established the 2025 goal as part of an ongoing effort to reduce dependency on resources such as fossil fuels and rare earth magnets. It represents an ambitious 89% reduction in motor volume compared to 2020 targets. This project is among the programs which the DOE’s Vehicle Technologies Office deems to “have the potential to support radical new vehicle architectures by dramatic volume/space reductions and increased durability and reliability.”

Motor in the wheel? Here is the proposal by Hitachi

In the past, various companies have already tried developing disruptive zero-emission motors, for instance with motors hidden in the wheel. This frontier has not technically found its benefit, yet, especially owing to the weight hindrance.
Hitachi, more precisely its subsidiary Hitachi Astemo, is trying giving a solution to the problem with the Direct-Drive. In practice, the manufacturer is going to integrate everything in a single component, placing in the wheel the motor, the inverter and the brake to achieve a power/weight ratio of 2.5 kW for each kg. In this way, they can partially eliminate wirings, as well as transmission gears, so improving efficiency up to 30%.
The prototype wheel is 19″, with maximum torque of 960 Nm, operation at 420 volt and maximum power of 60 kW: multiplied by four wheels, the total value would amount to 240 kW.
To avoid undesired contacts between the inverter components and the liquid, the cooling oil circulates in a ring among the various parts, by means of tubes, directly acting on power semiconductors, and then it is conveyed to the motor to cool coils.

A new research centre on electric motors

Due to the funds coming from the RRNP and from structural funds, Turin Polytechnics will collaborate with the Municipality of Pianezza in the creation of a Research Centre for the design of electric motors. The concerned area has been reclassified as “of collective interest ” and will be redeveloped. According to this vision, they have established an agreement that will last for three years: the Municipality of Pianezza must provide the spaces and the intervention projects to allow the start of the collection of events of interest for public and private subjects interested in contributing in the creation of the Centre. In its turn, the Polytechnics will provide the necessary scientific support for the activities of research, study and training that will be held in the centre. The project will permit the conversion of territorial companies through the enhancement of the role of the industry that manufactures motors and of the entire industrial sector chain.
The Rector of the Polytechnics, Guido Saracco, stated: «With this agreement, the Polytechnics adds another important step in the process of support and development for the territorial economy and for the small medium enterprises that are going to start a process of industrial reconversion. With these synergies, we will share in further boosting economy, employment and youth’s education ».

University of Perugia: the study on the efficiency of electric cars is starting

One of the hottest issues concerning the electric mobility is the motor efficiency. Concerning this, a study involves the University of Perugia, in the context of a graduation course in industrial engineering. The research programme involves also professors of triennial and master graduation courses in Industrial Engineering in Terni, as well as Genesi Energia company, operating in the sector of the electric mobility engineering and of manufacturing, stocking and use of electric energy from renewable sources.
The study provides for activities of modelling and experimental analysis in electric mobility applications and the creation of predictive models for the assessment of the charge efficiency and of autonomy depending on the mileage. Such predictive models, combined with experimental checks, will be applied on Renault Zoe electric car, made available by Genesi Energia.
«The analysis of efficiency and energy dispersion of the new electric mobility – explained prof. Ermanno Cardelli, director of the Engineering department of University of Perugia – is a still unexplored field that will be fundamental to work at the implementation of the distribution networks of electric energy on roads. Moreover, the research provides for the design and the implementation of a prototype of electric quadricycle with pedal assistance with photovoltaic panels on board: the design of the super light frame, combined with renewable energy sources on board, will allow achieving theoretically unlimited autonomy in day travels».
