Zunum Aero has a bold plan for a low-carbon flying future

Electric cars make up a growing share of the vehicles on our roads, but what about the aircraft in our skies? While it may be slower to gain traction, an electric revolution is set to take place in aviation technology. When can we expect to see a low-carbon flying future? What will the aircraft of [...] Posted in Motors,Motors Papers

Full speed ahead for electric cars

Electric cars were once an expensive novelty, mocked for slow speeds and limited range. However, a trickle of vehicles coming onto the market has become a steady stream and many countries are now setting dates for a ban on sales of vehicles with internal combustion engines. A fierce global competition is underway to determine the [...] Posted in Motors,Motors Papers

How to design an induction machine

The Induction Machine (IM) is the most widely used type of electrical machine. By some estimates it accounts for 90% of all small size motors (10 – 750W) and 60 -70% of medium size motors (0.75 – 375 kW). This is mainly due to their reliability, low cost and wide range of torque / speed [...] Posted in How to...,Induction Machines,Motors

Optimisation of Synchronous Reluctance Motors (SynchRels) using Opera

In the last few decades, the synchronous reluctance motor (SynchRel) has been relatively neglected in industrial, domestic and traction application because of the ascendency of permanent magnet (PM) and the ubiquitous induction (IM) motor. Recent volatility in rare earth PM prices and the unavoidable losses in IM’s have renewed interest in SynchRels – especially for [...] Posted in Motors,Synchronous Machines

How to design a linear machine

In this blog I will take a look at the design of linear machines, where advanced material models are being used in order to investigate the effects of hysteresis on the machine characteristic. Linear machines are electrical motors or generators which transform mechanical energy into electrical energy and vice versa, through the use of linear [...] Posted in How to...,Linear Motion,Motors,Motors Papers

Electro-mechanical System Analysis using Opera and RomaxDesigner

Presenter: Dr. Melanie Michon, Romax Technology Abstract: The design of integrated electrified drivelines requires a holistic electro-mechanical approach. However, often electrical and mechanical components are designed separately, and problems don’t occur until the complete system is assembled and tested. In particular NVH problems are often caused by interactions between the electrical and the mechanical sub-systems [...] Posted in General,Motors,Motors Papers

EUGM 2017: An alternative method of reaching a steady state operation point for electrical machines

Presenter: Florian Waldhart, Leitner Ropeways Abstract: A simulation of a steady state operation point is a main task for the simulation of electrical machines. Therefore, some methods will be presented which show the calculation procedure for getting such an operation point, starting with static simulations and ending up with different transient simulations. The main part of the [...] Posted in General,Motors,Motors Papers
