Mar 01, 2017· A piezo-disk energy harvester excited by rotary magnets (PE) is presented. Excitation force exerting on the piezo-disk is general periodic instead of harmonic. An analytical model for evaluating PE under a general periodic force is built. Multiple speed ranges make PE achieve peak and effective bandwidth is enhanced.
(7) and the exciter (8), the rotational force driven by the diesel engine (1) on the rotary shaft (9) connected to the flywheel (3) of the diesel engine (1) via a coupling (4) Power is generated by the generator field 6 and the corresponding generator 7.
Direct Force Exciters are predominantly used to drive vibrating conveyors, feeders and screens. It has two shafts fitted with unbalance masses, which are caused to rotate by integrated gears in opposed directions at the same speed. The directional force excitor is driven from an external standard electric motor via a universal joint shaft.

Feb 01, 2016· Therefore, a rotary valve-controlled electro-hydraulic exciter is designed and developed in this paper. A new type of two-dimensional rotary valve (called 2D valve, ) is redesigned as a power element of a three-way valve-piston combination in an electro-hydraulic exciter. The single spool of this 2D valve has both rotary and linear motions.
Rotor excitation systems are, in general, broadly classified into three groups according to the power source used for excitation (IEEE, 2006):. 1. DC excitation systems: Use DC generators to feed the field windings of the synchronous machine.. 2. AC excitation systems: Use AC generators with the help of rotary or static rectifiers to feed the field winding of the generator.

The system which is used for providing the necessary field current to the rotor winding of the synchronous machine, such type of system is called an excitation system. In other words, excitation system is defined as the system which is used for the production of the flux by passing current in the field winding. The excitation system is mainly classified into three types, DC excitation system ...
