Abstract
In a linear motor comprises one or more moving units provided to move linearly on a base frame, one or more magnetic field forming members to opposed each of the moving units, and moving means provided on said magnetic forming members for moving the magnetic forming members on the base frame by reaction force occurring when the moving units are driven, whereby vibration acting on the base frame at the time of moving of the linear motor can be cancelled by the motion of the magnetic field forming members.
