“…This operating point is the most interesting, since the highest losses are generated in the rotor core and permanent magnets, for which the cooling method is required. The software package Syr-e [19] was used to model the electromagnetic aspects and losses generated in the machine, where the AC losses of the simulated loss maps are rescaled based on the difference with the available total loss map from the manufacturer. The used losses are shown in TABLE V. These losses are distributed uniformly over the volume of the components Within the comparison a circumferential jacket cooling with water-glycol at 40°C is present in the housing and an oil flow rate of 10 l/min is used at an inlet temperature of 60°C for the hollow shaft and direct rotor cooling.…”

A novel direct rotor cooling method for electric machines is proposed and the performance is evaluated based on a thermal zonal model that is validated with measurements on a rotor heater setup. The trend of increasing power density of electric machines urges the need for high performance rotor cooling methods. A thermal model is needed to assess the performance of these methods on a certain geometry and to optimize the design. A previously developed thermal zonal model of an interior permanent magnet synchronous machine is extended with the novel direct rotor cooling method and validated with measurements on a rotor heater setup for different oil inlet temperatures (40 to 80°C), flow rates (0.5 to 10 l/min) and heating powers (261 to 873W). With a maximum absolute and relative deviation between the measurements and simulations of respectively 6.3°C and 13.3% on the maximum rotor core temperatures for flow rates higher than 1 l/min, it is concluded that the model is sufficiently accurate when taking into account the assumptions and uncertainties on the input parameters. A model based comparison with the validated model shows the great potential of the novel direct rotor cooling method to push the power density to higher levels, since the relative magnet temperatures can be decreased by 71% compared to a hollow shaft liquid cooled machine.

“…Generally, a large number of finite-element simulations is used to create flux-linkage "maps" of 𝜆 𝑑 and 𝜆 𝑞 on the (𝐼 𝑑 , 𝐼 𝑞 ) plane. In [19], a 15 × 15 mesh of (𝐼 𝑑 , 𝐼 𝑞 ) points were used. The fluxlinkage maps can also be found experimentally.…”

The IEEE Publication Services & Products Board (PSPB) last revised its Operations Manual Section 8.1.9 on Electronic Information Dissemination (known familiarly as "author posting policy") on 7 December 2012.PSPB accepted the recommendations of an ad hoc committee, which reviewed the policy that had previously been revised in November 2010. The highlights of the current policy are as follows:• The policy reaffirms the principle that authors are free to post their own version of their IEEE periodical or conference articles on their personal Web sites, those of their employers, or their funding agencies for the purpose of meeting public availability requirements prescribed by their funding agencies. Authors may post their version of an article as accepted for publication in an IEEE periodical or conference proceedings. Posting of the final PDF, as published by IEEE Xplore®, continues to be prohibited, except for open-access journal articles supported by payment of an article processing charge (APC), whose authors may freely post the final version.• The policy provides that IEEE periodicals will make available to each author a preprint version of that person's article that includes the Digital Object Identifier, IEEE's copyright notice, and a notice showing the article has been accepted for publication. • The policy states that authors are allowed to post versions of their articles on approved third-party servers that are operated by not-for-profit organizations. Because IEEE policy provides that authors are free to follow public access mandates of government funding agencies, IEEE authors may follow requirements to deposit their accepted manuscripts in those government repositories.

To improve the design of electric drives and to better predict the system performance, numerical simulation has been widely employed. Whereas in the majority of the approaches, the machines and the power electronics are designed and simulated separately, to improve the fidelity, a co-simulation should be performed. This paper presents a complete coupled co-simulation model of synchronous reluctance machine (SynRel) drive, which includes the finite element model of the SynRel, the power electronics inverter, the control system, and application examples. The model of SynRel is based on a finite element model (FEM) using Simcenter MagNet. The power electronics inverter is built using PLECS Blockset, and the drive control model is built in Simulink environment, which allows for coupling between MagNet and PLECS. The proposed simulation model provides high accuracy thanks to the complete FEA-based model fed by actual inverter voltage. The comparison of the simulation results with experimental measurements shows good correspondence.
