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) ...

Abstract: The following treatment of the starting of synchronous motors is intended to apply to polyphase motors and has been worked out for those of the revolving field type, but can doubtless be so ...

Abstract: FRACTIONAL-HORSEPOWER synchronous motors are generally available for quantity production in only the reluctance or hysteresis types. The reasons for this are: the simplicity of their rotor ...

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, ...

The e-Vitara is powered by a permanent magnet synchronous motor paired with two battery options: a 49kWh variant and a 61kWh variant, delivering ranges exceeding 500 km on a single charge. New Delhi: ...
