Latest Patents

Sunaga's latest patents include an advanced electromagnetic clutch assembly designed for use with refrigerant compressors in automotive air-conditioning systems. This assembly features a first rotatable member, such as a rotor, with an axial end plate made of magnetic material. The second rotatable member is connected to the outer end of the compressor's drive shaft. An armature plate, also made of magnetic material, is elastically connected to the second rotatable member and faces the rotor's axial end plate with an air gap in between. The electromagnetic device within the rotor is capable of attracting the armature plate into contact with the rotor's end surface, allowing the rotor's rotation to be transmitted to the drive shaft when activated. Additionally, the device includes first and second electromagnetic coils that generate a thermal difference when heat is conducted from the contact surface between the rotor and the armature plate. A control device manages the connection and disconnection of the electromagnetic device to the battery, ensuring optimal performance.

Another patent by Sunaga involves an electromagnetic clutch that incorporates an adjusting means for modifying the spring constant of leaf springs supporting the armature plate. This design allows for a gradual reduction in the gap between the armature plate and the pulley, resulting in a suction force that increases as the gap decreases. This innovative approach minimizes noise during operation by ensuring a soft collision between the armature plate and the pulley.
