Title: Synchronous linear motor
Inventor: AKAMI YUSUKE
IPC: H02K41/02
Filed: 2007-11-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a synchronous linear motor that ensures a good cooling effect by a simple configuration.  <P>SOLUTION: Coils and permanent magnets are disposed such that, when a moving member 5 is displaced within a normal stroke range, much driving current is caused to flow in U-phase coils 8UG (U-phase, -U-phase, and U-phase coils 8U, 8Uf, and 8U) of an armature 4. In the normal stroke range, mainly the U-phase coils 8UG (U-phase, -U-phase, and U-phase coils 8U, 8Uf, and 8U) generate heat. The heat thus generated is efficiently dissipated by means of cooling fins 10 disposed in a portion of a yoke member on the armature side which corresponds to the U-phase coils 13, hence the U-phase coils 8UG and then the armature 4 can be cooled efficiently. By providing the cooling fins 10 in the portion of the yoke member on the armature side which corresponds to the U-phase coils, which is near the U-phase coils 8UG which mainly generate heat, quick and efficient cooling can be performed, resulting in further facilitating the reduction in size of the cooling fins 10 and then the entire apparatus.  <P>COPYRIGHT: (C)2009,JPO&INPIT
