Gearing up to make even more complex molecular machines, chemists at the University of Groningen have created a molecular motor coupled to a rotor. The motor turns the attached rotor such that the two ...

ECM101, authored by ECM's R&D team and CTO Steven Shaw, Ph.D. illustrates how ECM's air-core axial flux motors ...

A compact wireless data acquisition system can investigate, monitor and optimise electric rotor motor operation, say Rolf Spellmeyer and Diego Llopis. In modern electric vehicles, different types of ...

American powertrain supplier BorgWarner has started production of e-motor rotor and stator for XPeng Motors, a leading Chinese Smart EV company. The components will be used on the X9 MPV as well as ...

Over the past several years, researchers have made great strides in creating synthetic molecules that act as rudimentary computer switches (SN: 9/20/03, p. 182: Available to subscribers at Molecular ...

A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.

In its standard form, the Mazda 13B Rotary engine has two rotors that make a distinct 'brap-brap' while at idle, and a 9,000 RPM scream on full tilt. It's a two-stroke dream of an engine with a cult ...

Why EV manufacturers are working toward eliminating rare-earth materials from their motors. An introduction to the wound-rotor synchronous motor (WRSM) architecture, and some of its innovative ...

This article was updated Feb. 20, 2023. It was originally published March 2, 2011. Engineers are constantly called on to select motors for the applications that will be able to do the task at hand and ...
