Abstract (en)
[origin: EP0945188A2] The device has a vibrating table (1) with unbalance shafts (2,3) with electric drive motors (8). The motors are servo motors with electronic motor regulator. A torque/phase position control device has sine-cosine transmitters, to determine angular position and torque of the unbalance shafts. The transmitters are connected to the shafts with a rigid transmission ratio of 1:1. The device has four shafts, which are coupled in pairs via toothed belts (7). Each pair is coupled to a separate motor, one being a master drive and one being a slave drive.
