Abstract
The present invention relates to an improved drive system for rotatable members in molding machines. The drive system comprises at least one frameless, brushless electric motor having a stator mounted to the machine and a rotor directly coupled to the rotatable member. Each rotor is coupled to the rotatable member so that the axis of rotation of the rotor is concentric to the axis of rotation of the rotatable member.
