SAFETY REQUIREMENTS ARE THE TOP PRIORITY FOR EXPERIMENTS

An extremely secure design is required due to modern drive systems and especially to experiments with high efficiency machines. For this reason many norms have been created or supplemented in recent years. The new machine system 4.0 fulfils all safety requirements for student experiments.

HEAVY-DUTY MACHINE BENCH & MECHANICAL LATCHES

A new, heavy-duty aluminium machine bench serves to fix the machines in place. Mechanical impulses, which can occur when IPM motors, synchronous motors or high efficiency machines stall, are absorbed by the bench and the mechanical latches on both sides. The machines can be moved around on the machine bench at any time so that two machines can be operated against each other on the machine bench. The installation of digital and analogue tachometers is possible without much effort.

INSULATION OF THE BASE FOR ELECTROMAGNETIC COMPATIBILITY (EMC)

All motors are insulated against the base so that unnecessary current loops do not increase interference radiation and stray leakage currents do not influence the measuring sensors.

This is the requirement for Industry 4.0-compatible frequency converters and servo actuators as well as the associated speed rotation angles and position sensors.

ADDITIONAL POTENTIAL EQUALISATION

Additional potential equalisation is necessary to protect people and the unit. A break in the protective conductor would put the machine or even the entire unit under voltage, as leakage currents could be conducted directly to the motor and the unit via the stator.

An additional protective conductor (potential equalisation) can be created to teach the problem in a class. A unit which is often used in medical technology with 6 mm connectors and 10 mm² wires (green/yellow) is used for this. This makes it possible to create an additional protective conductor or local potential equalisation quickly and as intended.

ACADEMICALLY PREPARED FOR BETTER UNDERSTANDING

The machines are all industrially manufactured, designed for education and equipped with a shaft end. The terminal board is on the top for the flexible set-up of experiments. The machines are partially opened and transparentelly covered so that important components are visible.

FURTHER SAFETY FEATURES

  • Temperature switch to protect against overheating
  • Automatic switch-off to protect against damage caused by overloading
  • All loose ends of wires are led out on the terminal board on 4 mm safety sockets
  • All measurements are isolated
