Motor Control Power Supplies
Typical brushless motors are permanent magnet synchronous AC motors, combined with sensor electronics (detecting rotor position) and an AC signal generator (Inverter) driven by a DC supply. Typical brushless inverters use a switched power supply pulse width modulation to generate an AC drive signal. Various terms are used to refer to the inverters/electronic control systems, including "Vector Drives", and "VVVF drives" (variable voltage variable frequency).

Famous quotes containing the words motor, control, power and/or supplies:
“This biplane is the shape of human flight.
Its name might better be First Motor Kite.”
—Robert Frost (1874–1963)
“I am the center of the world, but the control panel seems to be somewhere else.”
—Mason Cooley (b. 1927)
“He admired the terrible recreative power of his memory. It was only with the weakening of this generator whose fecundity diminishes with age that he could hope for his torture to be appeased. But it appeared that the power to make him suffer of one of Odette’s statements seemed exhausted, then one of these statements on which Swann’s spirit had until then not dwelled, an almost new word relayed the others and struck him with new vigor.”
—Marcel Proust (1871–1922)
“In short I must confide in you to take such care of the men under you as an economical householder would of his own family, doing every thing within himself as far as he can, and calling for as few supplies as possible. The less you depend for supplies from this quarter, the less you will be disappointed.”
—Thomas Jefferson (1743–1826)
