Patent ID: 7745963

Claim:
A linear motor with an integrated guidance, comprising: (a) a base plate comprising at least two side walls; and (b) a travel plate guideably connected to the base plate in a linearly movable manner, wherein the base plate and the two side walls form a mono-block, the mono-block comprising at least two longitudinal grooves for receiving a first runner rod and a second runner rod, wherein the travel plate comprises at least two longitudinal grooves for receiving a third runner rod and a fourth runner rod and is connected to a plurality of rollers that travel on the at least two longitudinal grooves of the travel plate, wherein cross roller cage is arranged in a floating manner between the mono-block and travel plate, the cross roller cage comprising a cage and a plurality of rollers that contact the runner rods, wherein a linear drive and a position measurement system are arranged in a region between the at least two longitudinal grooves of the travel plate, wherein a bias rod is arranged on one side in one of the at least two longitudinal grooves of the mono-block and is displaceable transversely to the running direction of the travel plate by way of a plurality of threaded bores incorporated in the corresponding side wall of the mono-block by way of pressing screws, the threaded bores being staggered in an alternating manner in the side wail, wherein a centric deepening is formed in the mono-block, in which a unit provided with a plurality of exciter coils is inserted, and wherein a longitudinal recess is formed in the travel plate in the surface which is directed to the base plate in the installed condition and serves for receiving a magnet unit, wherein a circuit board with supply leads for the exciter coils is attached laterally of the centric deepening in the mono-block along a longitudinal side, and wherein a circuit board with electronics for the position detection and the motor-specific data is attached on the other longitudinal side of the deepening, and wherein a receiver groove is formed in the lower side of the travel plate, which lies above the circuit board for the position detection, and in which a glass scale with an optically readable marking lies, which on movement of the travel plate, is moved past an optical measurement head which is arranged on the circuit board.
