Planar motor

A planar motor movable in an X-Y direction in a plane, comprising:

• a mover having an armature coil part installed on an armature frame;
• and
• a stator that includes a permanent magnet part comprising:
• a plurality of S-pole permanent magnets;
• a plurality of N-pole permanent magnets, wherein at least two corners of each of the plurality of S-pole permanent magnets each contacts a corner of a respective one of the plurality of N-pole permanent magnets and at least two corners of each of the N-pole permanent magnets each contacts a corner of a respective one of the plurality of S-pole permanent magnets;
• and
• a plurality of inserted permanent magnets positioned in spaces formed where the corners of the plurality of S-pole permanent magnets and N-pole permanent magnets contact.

A planar motor movable in an X-Y direction in a plane, comprising:

• a mover having an armature coil part installed on an armature frame;
• and
• a stator that includes a permanent magnet part comprising:
• a plurality of S-pole permanent magnets;
• a plurality of N-pole permanent magnets, wherein the plurality of S-pole permanent magnets and the plurality of N-pole permanent magnets are positioned on a surface of a stator frame facing the armature coil part of the mover, are alternately provided in rows inclined at a predetermined angle with respect to a longitudinal axis of the stator and are spaced apart from one another at intervals equivalent to a size of one of the plurality of S-pole permanent magnets or one of the plurality of N-pole permanent magnets;
• and
• a plurality of inserted permanent magnets arranged in spaces formed between the plurality of S-pole permanent magnets and the plurality of N-pole permanent magnets.
