People think that Raytheon engineer Percy Spenser, the chief of their power tube division, noticed that while working with a magnetron he found his candy bar had melted. This is, apparently, true, but ...

The two most important electric motors are the ac induction motor and the permanent magnet (PM) brushless synchronous motor, also known as the brushless dc or ac servo motor. These motors have ...

Permanent magnet synchronous motors (PMSMs) are AC synchronous motors that receive field excitation by permanent magnets. These motors have sinusoidal back-EMF and are similar to brushless DC (BLDC) ...

The AKM2G series from Kollmorgen deliver 30% more torque per rating than current designs without an increase in installed size. The new generation of synchronous servo motors feature six design sizes ...

There is a constant need and desire throughout the HVAC industry to spur innovation and create new products and ideas that can redefine the marketplace. In the realm of motors, the permanent magnet ...

Any electrical motor, from an idealized viewpoint, consists of two sets of magnets—one set stationary, one set free to move—placed in special geometric relation to one another. For most practical ...

What good is a fiber optic self-lighting Christmas tree if it flashes so fast it will put you into an epileptic attack? The answer is “Not very good”, if you ask [Mads Nielsen] a.k.a [EcProjects]. So ...
