the case of HPP Vinodol, it is evident that parts of the rotor pole are less efficiently cooled. The differences in temperatures on some pole positions are as high as 50°C measured under exploitation condition with ~30 MW active and ~ MVAr reactive power. According to measurement results, pole side closer to exciter is warmer than the

The rotor is the rotating electrical component. It also consists of a group of electromagnets arranged around a cylinder, with the poles facing toward the stator poles. The rotor is located inside the stator and is mounted on the AC motor''s shaft. The term "rotor" is derived from the word rotating.
A 1200rpm (sixpole) motor will reduce rotor speed by onethird while maintaining knifetip force, even with lower horsepower. A sixpole motor has 50% more torque than a fourpole motor. Changing a rotor pulley can be a less costly solution if there is sufficient room within the guarding for a larger pulley.
Jul 07, 2004· The grinder uses a shaded pole induction motor. This kind of motor has not brushes or capacitor. The poles of the rotor are fabricated in such a manner as to mechanically alter the magnetic field for startup. The grinder will spin freely as long as no current is applied. When current is applied, the

Stepper motor (2, 3, 5 phases). Close to the PM AC synchronous in its construction, except that the motor is made to maximise the number of stable equilibrium positions of the rotor (many alternating magnetic poles at the rotor or variable reluctance). Back emf depends on how it''s driven. AC asynchronous (3 phases).
The 1P24 PTO stump grinder is designed for small tractors equipped with hydrostatic drive and Category 1 3PH.
