Latest Patents

Sakai's latest patents include the "Canned Linear Motor Armature" and the "Canned Linear Motor." The canned linear motor armature features a design where both side surfaces of the armature winding are secured by two winding fixing frames, effectively sandwiching the armature winding in the longitudinal direction. A refrigerant passage is integrated into the space between the can and the winding fixing frame, ensuring efficient cooling. Additionally, a seal material is strategically placed to prevent refrigerant leakage, thereby protecting the armature winding. The design also incorporates a waterproof film on the surface of the winding fixing frame that comes into contact with the refrigerant.

The canned linear motor itself includes a winding accommodating frame shaped to house the armature winding, a flat plate-shaped connection substrate, and airtight cans that close both openings of the housing. Refrigerant passages are formed between the can and the winding accommodating frame, as well as between the can and the connection substrate. The construction is enhanced by an adhesive resin coating around the connection part, ensuring durability and reliability.
