"STATIC AND DYNAMIC BALANCING OF RIGID ROTORS" MACDARA MACCAMHAOIL | BRÜEL & KJÆR DOWNLOAD PDF. Unbalance in a rotor is the result of an uneven distribution of mass, which causes the rotor to vibrate. The vibration is produced by the interaction of an unbalanced mass component with the radial acceleration due to rotation, which together generate a centrifugal force.
The vibrations produced lie in the low frequency range. The construction of working device and its important parts are described here. The most important part of exciter is unbalanced mass attached with rotating disc of motor. Exciter has unbalanced mass at one end of disc, base frame, top plate as platform, springs and motor.

Unbalanced Motor Driven Feeder. The Vibrating feeders are used for conveying bulk material for control feed and are used where products are to be fed either continuously or in batches. For example – Discharging bulk material from bins and Feeding crushers, mixers, furnaces, scales, bucket elevators, screens and conveyor belts.
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 ...
Problems related to design of high-performance vibrating machines are described in this paper. For this purpose, numerical simulation of flat solid body oscillations excited by two unbalanced exciters was carried out. The developed model takes into account AC motor characteristics. A control system for automatic resonant tuning under varying system parameters is developed.
From the perspective of theoretical derivation, numerical simulation, and engineering application, the vibratory synchronization characteristics of a dual-mass vibrating system driven by two exciters, were studied. The differential motion equations of the total system were calculated using Lagrange's equations, and the responses of the vibrating system in the steady state were derived by ...
Unbalance Motors Series JX. Unbalance motors are electro-mechanical drive units which generate circular oscillations. In contrast, linear oscillations are produced by operating two motors working in opposite directions. With the motors off, the oscillation amplitude can be set for all JVM ® unbalance motors by adjusting the centrifugal weights.

An electric generator or electric motor consists of a rotor spinning in a magnetic field.The magnetic field may be produced by permanent magnets or by field coils.In the case of a machine with field coils, a current must flow in the coils to generate the field, otherwise no power is transferred to or from the rotor.
The unbalance exciter may only be taken into use if it has been correctly installed with the respective machine and all protective devices. All maintenance and adjustment work on the unbalance exciter may in principle to be carried out with the machine at a standstill. Steps must be taken to ensure the unbalance exciter

When the axes are parallel but not exactly aligned, the condition is known as parallel misalignment.
Coordinate of rotation center o i (i = 1, 2) of vibratory motor can be determined by geometrical parameters β i (rad) and l i (m). Furthermore, when the exciters are operated in dynamic coordinate frame x"o"y", fixed coordinate frame xoy can be obtained by introducing transformation principle of …
A standard hydraulic or 3-phase motor is used as the drive motor. Please note that the highest admissible speed of the exciter may not be exceeded and that the motor's starting torque must be 2.5-times that of the nominal torque. Where extremely wide or heavy machines are concerned, several exciters can be operated in series with one drive motor.
The work principle of one of the possible configurations in this exciter is considered and provided. One inflexible and two mobile unbalances are strengthen on its unbalanced shaft.
Jul 12, 2019· The working principle of the vibration exciter The one-way inertial exciter generally consists of two rotating shafts and a pair of gears with a speed ratio of 1. The two rotating shafts rotate in opposite directions at opposite speeds, and the two eccentric blocks on the shaft generate a resultant force of inertial forces in the Y direction.
Thus unbalance exciters generate a linear vibratory motion. They are used to drive vibratory conveyors, screens and other vibration systems with very high load and/or very high flow rates. It may be noted that working of unbalance exciters is similar to use of two counter-rotating unbalance motors to generate linear vibratory movement.
AViTEQ Unbalance exciters are designed for producing linear motion for medium and large size vibrating machines operating in many industrial processes. The design is engineered for safe operation in continual operation with centrifugal force. In order to archieve higher working moments it is possible to use number of exciters parallel in line.
