Abstract

PURPOSE: To move a magnet at constant speed in a linear motor by disposing two sets of drive coils at special interval at the magnet having alternative north and south poles and flowing current proportional to the magnetic field intensity at the respective coils.
CONSTITUTION: A magnet 16 is so magnetized alternatively at north and south poles as to become sinusoidal waves in magnetic flux distribution and movably mounted at two guide members 14, 15, and two sets of drive coils 10, 11 are provided at an iron core 9 provided in parallel with the guide members. A plurality sets of the drive coils 10, 11 are provided at an interval of the magnetized wavelength λ of the magnet 16 in such a manner that the drive coils 10 and 11 are spaced at an interval of λ/4. Further, elements 17, 18 for detecting the magnetic field of the magnet are provided at the respective coils 10 and 11 to thereby flow the currents proportional to the detected magnetic field intensity. Thus, the magnet 16 can be moved at constant speed.
