Guest Editorial: Advances in electric machines — solutions for electro‐mobility with improved characteristics.

The obtained results clearly show that the 14-pole PM machine has a slightly larger torque output, a better overrating torque capability and a significantly lower risk of PM irreversible demagnetisation. The efforts of mankind focussed on the reduction of global warming and carbon dioxide emissions, achievable through the reduced usage of fossil fuels, strongly influence the development of the entirety of engineering. Feng et al. conducted a comparative study of dual 3-phase permanent magnet (PM) machines with coil spans of two slot pitches, analysing the 24-slot/10-pole and 24-slot/14-pole machines with windings displaced by 30°.
