Patent attributes
A linear motor assembly includes two stators extending in parallel and having salient poles arranged at a predetermined interval on opposing surfaces and a mover having three types of mover blocks. The mover blocks are made up of three-phase alternating current coils configuring magnetic poles of three phases and permanent magnets arranged in alternating polarities on two surfaces of the mover blocks opposing each of the two stators. The mover blocks are movable between the two stators along a direction in which the stators extend. A plurality of linear motors are arranged in parallel with respect to a travel direction of the movers, and the stators provided between adjacent movers are integrally formed such that they have said salient poles on the two surfaces opposing these movers.
