FREQUENTLY ASKED QUESTIONS – PERMANENT MAGNET AC
FREQUENTLY ASKED QUESTIONS – PERMANENT MAGNET AC

... What are some of the major differences in performance between AC Induction and PMAC? The most obvious performance difference is that a PMAC motor rotates at the same speed as the magnetic field produced by the stator windings; i.e. it is a synchronous machine. If the field is “rotating” at 1800 rpm, ...

Voltage optimisation

Voltage optimisation is a term given to the systematic controlled reduction in the voltages received by an energy consumer to reduce energy use, power demand and reactive power demand. While some voltage 'optimisation' devices have a fixed voltage adjustment, others electronically regulate the voltage automatically.Voltage optimisation systems are typically installed in series with the mains electrical supply to a building, allowing all its electrical equipment to benefit from an optimised supply.
