DC motors come in many forms, but they all have the same job: turning electrical energy (DC) into mechanical energy. Although DC motors have a common operating principle, many applications—including ...

Electric motors are easy to make; remember those experiments with wire-wrapped nails? But what’s easy to make is often hard to engineer, and making a motor that’s small, light, and powerful can be ...

Finding just the right off-the-shelf part to complete a project is a satisfying experience – buy it, bolt it on, get on with business. Things don’t always work out so easily, though, which often ...

Researchers have succeeded in constructing the coil of an electric motor using only carbon nanotubes without any metals, and realizing it to the point where it can actually run. (Nanowerk News) ...

The LVCM-010-013-01 linear voice coil motor is 0.375 in. (9.5 mm) in diameter and the length at mid-stroke is 0.81 in. (20.7 mm) long. This miniature voice coil motor has a high force-to-size ratio ...

A research achievement that breaks the conventional belief that metal is essential for electric motor coils has emerged in the country. This technology, which utilizes carbon nanotubes (CNT) instead ...

Siemens has developed a new type of ship motor that uses superconductor technology. Superconducting materials are used for the rotor windings, which are housed in a closed system cooled down to -246°C ...

Both the brushless DC (BLDC) and permanent magnet synchronous motor (PMSM) require electronic commutation in order to create a rotating electromagnetic field, which is needed to turn the rotor. Both ...
