Abstract

The present invention provides a linear motorwhich uses a plurality of cylindrical linear motorsto increase power and which can guide forward and backward movements using a simple configuration, the linear motorrequiring reduced manufacturing costs. A plurality of cylindrical linear motorsare provided each of which has a shaft membermade of a permanent magnet and a coil unit. A motor supportis provided which is able to support the coil units of the plurality of cylindrical linear motorsarranged in parallel. The shaft members of the plurality of cylindrical linear motorsare coupled together at ends thereof by coupling members. A guide mechanismis located inside the arrangement of the cylindrical linear motorsto guide movement of the shaft membersof the cylindrical linear motors. The number of guide mechanismsis smaller than that of the cylindrical linear motors. For example, the single guide mechanismis provided.
