Abstract (en)
[origin: EP0949183A2] The carriage is driven along a rail (1) by a wheel (7) rotated through a worm drive (7b) by a direct current electric motor (7a). The rate of increase of the motor torque and the motor voltage during startup is then compared with the driving torque and motor voltage to initiate braking.
