Abstract: A drive control device having an inverter with semiconductor switches controlled by control signals is operated by calculating with a control logic a control signal time instant for each control signal, transmitting during operation the control signal time instants with the control logic during switching pauses of the semiconductor switches from a low-voltage side of the drive control device to a high-voltage side of the drive control device having the inverter, and generating the control signals for controlling the semiconductor switches on the high-voltage side based on the transmitted control signal time instants.

Abstract: There is described a roller drive and a roller transport device equipped with the roller drive. The roller drive comprises an electric machine and ends, wherein at least one end has a heat-conducting end contact face. The contact face is intended for coming into heat-conducting contact with a side cheek of the roller transport device. This allows the cooling to be improved. Furthermore, the roller drive can also be designed in such a way that it has a device for accommodating electrical components, wherein the device is intended as a torque support for the electric machine. A regulating device and/or a communication device can also be integrated into the device.
