The invention relates to a conveyor roller drive for a hot flue, comprising several drive motors for each roller group. In order to ensure that the drive motors produce an even product tension, even in shrinkable products, between the individual rollers of the roller group during stationary operation and also during a rapid start or disconnection of the machine, the drive motors are embodied as rotary current asynchronous motors which are electrically coupled in a parallel manner, which are connected to a vector converter and which are identical with the exception of a guide motor. The vector converter comprises means which are used to adjust the slip speed of the motors. |
