Torque is improved in a composite torque rotating electric machine that uses permanent magnets having a low residual magnetic flux density such as ferrite magnets, and includes: a stator comprising armature windings arranged at a fixed interval at multiple positions on the inner periphery; a rotor which has a permanent magnet in a cylindrical core comprising laminated magnetic steel sheets and is arranged inside of the stator; and magnetic flux blocking units provided across the circumferential direction on the outer periphery of the rotor that block the closed loop magnetic flux generated around the stator windings. The magnetic flux blocking units can be multiple permanent magnets, with a non-magnetic body such as an air gap disposed between them. The distance between the permanent magnets and the non-magnetic part can be smaller than the interval at which the armature windings are arranged.

Composite torque rotating electric machine

A composite torque rotating electric machine includes a stator having armature windings arranged at multiple positions in a circumferential direction, a rotor having a cylindrical core, first permanent magnets arranged on axes (d) and in the circumferential direction on the outer periphery of the rotor, second permanent magnets arranged on axes (d) on the inner periphery side of the rotor across from the permanent magnets on the outer circumference side, third permanent magnets on axes (q) and extending in the longitudinally and radially of the rotor, and air gaps on the outer periphery side of the third permanent magnets and intermediate in the circumferential direction of the first permanent magnets. The radial distance between the first and second magnets is greater than the circumferential distance between the first permanent magnets and the air gaps. A rectifier having multiple slits is disposed between the first permanent magnets and the air gaps.

This invention is intended to provide a large-capacity servo press apparatus driven by multiple motors, the servo press apparatus enabling a drive at a high efficiency and with reduced torque pulsations in a simple structure. The disclosed servo press comprises a slide that is moved up and down by a plurality of crank structures (including eccentric rings and connecting rods), main gears that drive the crank structures, a plurality of drive gears interlinked with the main gears directly or indirectly, intermediate gears interlinked with the main gears directly or indirectly, and servo motor sets connected to drive shafts to drive the drive gears. In each of the servo motor sets, a plurality of servo motors are directly connected to each servo motor shaft.
