Abstract: A magnet controller for a magnetically suspended vehicle of the linear stator type for travelling along a rail track (1) forming a linear stator having teeth of uniform determined width, responds to a rectified control signal. The control parameters for the magnet controller (21) are adjusted in response to speed to assure a stable control during standstill and at low speeds and to achieve a good response or follower characteristic of the control system at high speeds. A speed representing signal (U.sub.v) is generated in a conductor loop, preferably a double loop (9), inserted into a groove (10) of the poles (5) of the levitation magnets (2). The signal (U.sub.v) generated in the conductor loop is rectified at (31), and if desired passed through a low-pass filter (32) to provide the control input signal for the controller (21) by a very simple circuit. Utilizing just the amplitude of the speed signal (U.sub.

Abstract: An excitation arrangement for a long stator drive, particularly a synchronous long stator drive for rapid transit systems having combined generation of propelling and carrying forces comprises at least one heteropolar magnet which has a plurality of channels extending at right angles to the long stator direction and which are open at their pole plane lying opposite the long stator and in which magnetic coils assigned to the conductors are disposed. In order to improve the dynamic properties of the magnet, a subdivision of the magnetic coils generating the magnetic field is provided. Differing electrical behavior for slow and fast changes in the voltage driving the coil current is achieved by a tight coupling of one of the sub-coils to a short-circuit coil. Given slow changes in the drive voltage, a magnetic force resulting from the entire coil flux occurs. Given fast changes in the drive voltage, a dynamic reduction of the effective coil inductance leads to a fast current and magnetic force changes.
