Among three-phase power supply the synchronous machines are widely used and they called so because the speed of the rotor of these machines are the same as the rotating magnetic field. They are commonly used as generators especially for large power systems, such as turbine and hydroelectric generators in the grid power supply. Because the rotor speed is proportional to the frequency of excitation,synchronous motors can be used in situations where constant speed drive is required. Since the reactive power generated by a synchronous machine can be adjusted by controlling the magnitude of the rotor field current, unloaded synchronous machines are also often installed in power systems solely for power factor correction or for control of reactive kVA flow. Their construction is almost similar to that a three-phase induction motor except the fact that the rotor is given DC supply.

The Alternating Bending Fatigue Machine is a further evolution of the popular Rotating fatigue Machine. All these parts are enclosed by a transparent safety guard, which ensures rotating components are kept away from the user but full view of parts and count is kept. Rather than rotating a specimen to fatigue failure, the Alternating Bending Fatigue Machine induces an alternating displacement to the free end of a cantilevered test specimen in order to fatigue fail the part. A heavy base plate houses the control box, motor, fluctuating components, test specimen and digital counter.
Experimental Capabilities:
Reading and working with nomograms
Cantilever test specimens
Bending fatigue of a cantilevered strip of metal or plastic in modes varying from alternating to fluctuating stresses

Torsion Testing Machine (30Nm) can cater for test specimens of up to 750mm. Standard hexagon drives are used for transmitting the torque into the specimens. An angular compensation system is integral to the torsion head with a dial gauge. The Torsion Testing Machine (30Nm) head measures the applied torque to the specimen using strain gauge technology. Data Acquisition Software is supplied to capture the test parameters and to display the graphs relevant to further work. The strain gauge signals are fed directly into the Data Acquisition Interface supplied.

The sheet metal is clamped between the two by anelectromagnet capable of clamping with a force range of between 3-10 tons. The fundamental Principle of the Magnetic Bending Machine is that it uses electromagnetic, rather than mechanical, clamping system. Rotating the bending beam then forms the bend. The sheet is bent around thefront edge of the clamping bar. The machine consists of a long electromagnet with a steel clamp bar located above it. They have application in many ways with fourvarious sets clamping bars.
