Title:
ROTARY DRIVE
Document Type and Number:
Japanese Patent JP2023104321
Kind Code:
A
Abstract:
To provide a rotary drive that can prevent decrease in output torque and characteristic fluctuation by reducing heat generation, avoid decrease in life span and hindrance to maintenance, and contribute to further compactification (thinning).SOLUTION: A rotary drive comprises: a movable member Mm having a ring-shaped rotor yoke 5 and rotor magnets 4 in which multiple magnetic poles are arranged along the circumferential direction Ff of the rotor yoke 5; a fixed body Mc in which multiple stator cores 2c ... facing the movable member Mm are arranged at predetermined intervals on a ring-shaped stator 2 along the circumferential direction Ff; and a heat dissipation mold unit 9 in which at least part of stator coils 3 ... wound up around stator cores 2c ... is covered with an insulation covering material 7 with thermal conductivity, the insulation covering material 7 contacts at least part of the stator cores 2c ..., and the insulation covering material 7 contacts or approximates to the inner surface 8i of an outside-facing housing unit 8.SELECTED DRAWING: Figure 1
