The vibrations are induced by inhomogeneous flow fields. The accessory set induces the vibrations magnetically. Three fan rotors with differing numbers of blades can be investigated. Vibration measurements on fans and blowers play a major role in field monitoring operations. In addition to the usual signals caused by bearings and imbalance, the vibrations induced by the fan blades can be measured. A guard plate covers the rotating fans. Just as in actual practice, the fan model can also be driven directly via a flexible coupling or by the belt drive. An obliquely-mounted inertia disk is used to investigate the gyroscopic effect.

The Variable Frequency Ac Drive Learning System features heavy-duty, real-world components a Powerful ex4 variable frequency drive, multi-turn potentiometer for speed control, and selector switches for general drive control, performing basic stop start, ramping, and dynamic braking. The Variable Frequency Ac Drive Learning System adds to Motor Control Learning System to teach hands-on skills and industrial applications where variable frequency drives (VFDs) are used to vary the speed of an otherwise fixed speed AC motor. Learners then practice hands-on skills like programming and operating a variable frequency AC drive to ramp a motor up to its rated speed and decelerate to a stop. Common applications for VFDs include fans, pumps, conveyors, mixers, grinders, hoists, and many more. Learners will work through unmatched curriculum and study about the operation, installation, design, performance analysis, and troubleshooting of variable frequency drives. These real-world components help to prepare learners for situations that they will encounter on the job.

The deflection of the bar as result of the travel of the dynamometers and the horizontal alignment can be compensated and regulated using two adjustment bolts. This demonstration unit facilitates the experimental investigation of the progression of the bending moment and shearing forces on a bar subject to point loads. Due to the use of a low friction joint with two degrees of freedom at 1/3 of the span and two dynamometers, the measurements can be recorded directly from the bar. The bar is loaded with graduated sets of weights that can be attached at any point on the bar. In addition, the section principle commonly used in mechanics can be demonstrated.

The main part of the apparatus is a precision-engineered rigid aluminium base, with legs and levelling feet. At one end is a loading device which uses a screw to apply loads to the struts. The screw is in fixing blocks with bearings to give precise and easy load application. The Loading and Buckling of Struts allows tests on a full range of struts. They allow students to create any combination of pinned or clamped end conditions for the strut under test. Supplied is a set of special end fittings for tests with various eccentricities to show the effect of eccentric loading. It shows load and deflection characteristics and buckling loads for various strut lengths, Cross-section and end conditions. It also allows studies of the effect of eccentric loading. The equipment includes a lateral pull attachment for Students to apply light biasing loads, or larger side loads, as needed. Students can also set up the apparatus to examine flexural rigidity and general beam deflection theory. An optional set of extra specimens allows extra tests to show students some of the more complicated problems found in strut design. Holders are at both the loading and load measuring ends.
The two special struts show how buckling loads may be lower than the ideal values, because of two reasons:
Imperfect shearing connections between the parts of a compound strut
Flexure of the end fixings.
The angular position of the cam is shown on a protractor and a pointer, this assembly allows the cams position through rotation to be recorded. A vertical pillar contains the main spindle for each Cam Analysis Apparatus to be rotated, whilst a dial gauge has its anvil resting on the top edge of the cam. The rise and fall displacement of the Cam Analysis Apparatus, as it rotates through 360°, is measured using a dial gauge. Cams and followers are easily changed and graphs for the variety of cams can be created to compare the linear change with the rise and fall of the follower. Each cam is mounted on a central shaft and is free to rotate about this shaft. The cams are rotated by hand.
Experimental Capabilities:
To derive the velocity and acceleration diagrams, and determine the maximum acceleration of the follower
To compare experimental and calculated results
To determine a graph of follower displacement against angular rotation of the cam
To assess the effect of different cams and followers.
