Rethinking Climate Change on the Role of Human Power Generation, Alternative Perspectives, Potential Solutions, and a Plea for Action

Chemie Ingenieur Technik, EarlyView.
All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...

Refinement of Analytical Current Waveform for Acoustic Noise Reduction in Switched Reluctance Motor

IEEE Open Journal of Industry Applications
In this article, a refinement algorithm of the current waveform that flattens the radial-force sum in switched reluctance motors is proposed. Flattening the radial-force sum eliminates the multiples of the third radial-force component.

Influence of PWM on the proximity loss in permanent magnet brushless AC machines [PDF]

, 2008
The winding copper loss can be significantly increased due to skin and proximity eddy current effects. The skin and proximity losses due to fundamental frequency current has been investigated in literature, but the influence of PWM on the skin and ...

ISO efficiency curves of a two-phase hybrid stepping motor [PDF]

, 2010
Stepping motors are used in numerous applications because of their low manufacturing cost and simple speed control. It is well known that their energetic efficiency is low but actual values are typically not available.
