Assume a 3 phase AC Induction motor. The speed of the motor is derived by the formula N = (120/f)/P. N speed, f - frequency, P number of poles. In an induction motor P is fixed by the winding. f system frequency. Variable speed drives change the system frequency so that the speed (N) can be varied. Drive is a power electronic device through which the system frequency can be varied

How does a furnace multi speed motor work?
Mutli speed furnace motors work on a basis of horse power verses work load. The motor actually contains multiple windings or you could say multiple motors. Each of the windings has a specific horse power rating at a given work load. For example, a 3 speed 1/2 horse power motor is actually 3 different horse powers. High is 1/2 hp - medium is 1/3 hp - low is 1/4 hp. As the motor horse power is decreased the motor will slow down under a given or constant work load. Technically there is no such thing as a multi speed motor but in actuality a multi horse power motor.
Abrasive jet machining?
forcing abrasives over work piece at higher speed for cutting . it is unconventional machining process .
Mechanism of tiptronic gear transmission?
The mechanism of the tiptronic gear transmission is rotation. The tiptronic gears are usually an automatic transmission that allows the driver to control the gears like it is done in a manual transmission.
How do mechanical door closers work?
They use Hydraulic fluid that is pressurized by the opening of the door to control gears speed to allow for a steady closing of the door . Most have valve adjustments that increase or decrease the pressure to allow the door to speed up or slow down.
