at slow speeds idle since on one rotation of the pulley will cut through 3 magnetic flux fields instead of just one. Current output of like rated units at high speed will be the same with both types. Brush stationary structure, which provides a constant magnetic field, and a set of rotating windings called the armature which turn within that field. On small machines the constant magnetic field may be provided

hai archita,ac drive means operate with a current that alternates in the direction of flow 60 times per second HZ. If this frequency of alternation is changed, the speed of the motor changes. By controlling the AC frequency with a variable frequency drive, you control speed. A proper voltage to frequency ratio V/HZ must be supplied. For most industrial motors manufactured in the US this ratio is 460

, or having their rotor connected in the form of a self-starting circuit. Since the field is rotating at synchronous speed, the motor must be accelerated before it can pull into synchronism. Accelerating from, removes field excitation at rotor pullout, and protects the squirrel-cage windings against thermal damage under out-of-step conditions....A synchronous electric motor is an AC motor distinguished by a rotor

on rising forever. The speed with which you need to throw the rock in order that it just barely escapes the planets gravity is called the "escape velocity." As you would expect, the escape velocity to fall down again.If you threw the rock hard enough, though, you could make it escape the planets gravity entirely. It would keep on rising forever. The speed with which you need to throw the rock in order

By combining the high speed of static RAM and the high density of DRAM, proponents say MRAM could be used to significantly improve electronic products by storing greater amounts of data, enabling metal as magnetoresistive if it shows a slight change in electrical resistance when placed in a magnetic field.
