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.
Claims14
A molding machine comprising:
- a rotatable member for transportina molded articles from a first position to a second position, said rotatable member having an axis about which said member rotates;
- and
- drive means directly coupled to said rotatable member for rotating said rotatable member, said drive means comprising at least one electric motor having a stator and a rotor, said rotor having an axis of rotation coincident with the axis of rotation of said rotatable member.
