Drive unit for plastics injection machines

A drive apparatus unit for components of a plastics processing machine includes a motor unit which is provided with a rotor having a hollow shaft, and a thrust bearing assembly for mounting a driveshaft of the plastics processing machine. The thrust bearing assembly is fully or partly disposed within the hollow shaft. By arranging the thrust bearing assembly within the hollow shaft, the size of the drive apparatus is reduced to the size of the motor unit.
