The Key Components of the Linear Drive System are:

The Key Components of the Linear Drive System are:

  • Segmented drive (motor elements), each consisting of a number of stators
  • PCU (Power Control Unit) – controls the individual segments of the drive
  • Sensors and SCU (Sensor Control Unit) – localises the trolley or gondola and measures its speed
  • XPC – evaluates information provided by SCUs, measures the current phase position and synchronously controls the VFI
  • VFI (Variable Frequency Inverter) – powers the drive segments with alternating current and thus to provides the travelling magnetic field
  • Operations control computer, diagnostics system, user interface and interface for remote diagnostics
  • For reliable and fast real-time communication, optical fibres are used (additional advantage: no induced currents !); slower signals travel on an industrial bus system. The computers are linked by Fast Ethernet.
  • The entire system is controlled by an application-specific user interface (PLC). There, the system will also display all important status information and allow for diagnostics and trouble-shooting.
  • built-in modem allows the product specialists at InTraSys to directly look into the heart of the system and thus to trace any problem.

Some Technical Data of the ‚Superman‘ in California

The gondola, wheighing 7 metric tons (some 15.500 lb.) is accelerated to a speed of 160 km/h (some 100 mph) within seconds. After a vertical upward journey of some 126 m (415 ft.) it falls down freely. Passengers are weightless for some 6 seconds!.

  • Reverse Free Fall
  • LSM Drive
  • Linear Eddy-Current Brakes
  • Payload per Gondola: approx. 7 metric tons (approx. 15.500 lb.)
  • Maximum Velocity: 45 m/s (= 160 km/h or 100 mph)
  • Maximum Acceleration: 2 g (20 m/s²)
  • Mechanical Thrust: 1,5 MW
  • VFI power rating: 2.500 kVA
  • Rated Reliability of the Drive: 10 ppm
  • Six Flags Magic Mountain Park
  • The gondolas are accelerated to a speed of 160 km/h (100 mph) and vertically shot upwards to an altitude of some 126 m (415 ft.) above ground. Then, the gondolas fall down freely in reverse direction. The passengers get weightless for about six seconds. The reliable and fail-safe InTraSys Prolim eddy-current brakes decelerate the gondolas after the ride
