The Hybrid Demonstrator Trainer includes a Hybrid engine, a battery and an Electronic Control Unit, several meters showing power flow between the units, a brake switch and a potentiometer mimicking the accelerator pedal. The system can also be used to show the effects of regenerative braking. Two models are available: a bench top version and a panel mounted version. The controls the system to show students how the power is routed in a hybrid depending on the State of Charge of the Battery, and to allow them to make measurements on the engine performance under different load conditions.

For use with the Work Panel the kit allows several experiments with a suspension cable.
The versatility of the kit means that you can create symmetrical and non-symmetrical cables, with point loads or with evenly-spread loads.
Students or teachers fit the magnetic parts of the kit to the Work Panel to study or demonstrate the shapes and tensions in a suspension cable.
The kit compares a suspension cable with a catenary cable and analyses results using catenary and parabolic theory.
It includes a roller chain (the cable), held by magnetically mounted sprocket pulleys and a set of weight hangers and weights. Spring balances measure the tension in the cable.
Experiments:
Comparison of a symmetrical suspension cable and catenary
Unsymmetrical suspension cable
Analysis using catenary and parabola theory
A point load on a suspension cable
Cable weight and tension.

The kneading machine in this system is based on the machines that are commonly used in the food industry. Industrial kneading machines are widely used in food, medicine, rubber, paper and other industries. With reference to the actual teaching needs, the system includes the PLC control, variable frequency control, temperature control and touch screen control that are commonly used in industry, and covers the experimental trainings in sensor detection technology, food process control, power distribution technology and other subjects. They can realize stirring for a variety of raw materials and can also achieve heating at the same time.
General Features:
The trainer is composed of three independent modules:
The kneading machine,
The main electrical cabinet,
The control cabinet.
Hydraulic cylinder with hydraulic pump to generate pressure
