A tube pump in which the rotor is axially supported by permanent magnets at each end, so arranged as to apply attractive force across the gap between the rotor and a stator such that permanent magnets provide the sole radial support for the rotor. The axially effective permanent magnets are provided in conjunction with an electromagnetic stabilizer restoring the axial position of the rotor upon a shaft toward one or the other of the opposite ends thereof. |
