While BMW has done away with rare-earth metals entirely via its AC brushed motor, other manufacturers are looking to minimize their usage of these metals without reducing power output. The next major ...

AC motors are electric motors which are powered by alternating ... In other words, voltage is ‘induced' in the rotor through electromagnetic induction, eliminating the need for brushed or slip ring ...

Brushless motors are synchronous electric motors that have a magnetically (AC induction) or electronically (DC) controlled commutation system instead of a brush-based mechanical commutation system.

Usually, though, we’re talking about fancy brushless motors or steppers. The humble DC brushed motor is again left out in the cold. This project is aiming to fix that. It’s a smart motor ...

A motor — or a generator — requires some normal magnets and some electromagnets. The usual arrangement is to have a brushed commutator that both powers the electromagnets and switches their ...

Scout Motors, now owned by VW, showed off a new SUV and pickup, with battery electric and range-extended powertrain options.

Clean the coils using a soft bristle brush, AC solvent, or mild detergent ... the refrigerant won’t flow smoothly and the fan motor will accelerate, which will wear out the unit.

Remove these by hand, then dust off the coils using a coil brush. Available at most big box hardware stores and AC shops, this specialty cleaning tool (also known as a soil brush) has bristles ...

It’s a science fair classic that beats the pants off Billy Sedgwick’s papier mâché volcano. Electric motors—AC, DC, brushed, brushless, synchronous or not—all use electromagnetism to turn electrical ...
