Webrotor slots then shorted together at either end of the rotor using copper or aluminum “shorting” rings. Shorting rings are commonly referred to as end rings. The rotor bars are welded, brazed, or bolted to the end rings. If it is a cast aluminum rotor the shorting ring and the rotor bars are cast at the same time and no connecting joints exist. WebThe permanent-magnet rotor tracks with synchronism the stator rotating field, and therefore the rotor speed is equal to the rotating magnetic field speed. A wide variety of configurations is possible, and the two-pole version can be seen in Fig. 8. Motors of this sort have output ranging from about 100 W up to 100 kW. template timeline kegiatan https://mjengr.com
