Title:
AIR-GAP ADJUSTABLE LINEAR ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2022/041408
Kind Code:
A1
Abstract:
An air-gap adjustable linear electric motor (100), which comprises a base (1), a sliding seat (2), a first sliding rail (3), a second sliding rail (4), a stator assembly (5), a mover assembly (6) and an air-gap adjusting assembly (7). The stator assembly (5) and the mover assembly (6) interact to drive the sliding seat (2) to linearly move relative to the base (1). The air-gap adjusting assembly (7) comprises two positioning blocks (71), a first inclined block (72), a second inclined block (73) stacked on the first inclined block (72), and a micrometer (74), wherein the first inclined block (72) is provided with a first guide wall (721); the second inclined block (73) is provided with a second guide wall (731); the positioning blocks (71) are respectively recessed to form a first groove (710) and a second groove (711); the first guide wall (721) is clamped in the first groove (710) and forms a sliding connection with the first groove; the second guide wall (731) is clamped in the second groove (711) and forms a sliding connection with the second groove; and the micrometer (74) drives the first inclined block (72) to move along the first groove (710) so as to drive the second inclined block (73) to move in a movement direction perpendicular to the sliding seat (2), and drives the stator assembly (5) or the mover assembly (6) to move synchronously. An air gap of the air-gap adjustable linear electric motor (100) is convenient to adjust, such that the performance thereof is better.
