Title:
LINEAR MOTOR
Document Type and Number:
WIPO Patent Application WO/2022/047941
Kind Code:
A1
Abstract:
A linear motor (10), comprising a sliding mechanism (13), and a primary mechanism (11) and a secondary mechanism (12) spaced apart and arranged on the sliding mechanism (13). The secondary mechanism (11) comprises a first secondary unit (121) and a second secondary unit (122) arranged in parallel in a vertical direction; the first secondary unit (121) comprises a first magnetic yoke (1212) and a first magnetic steel (1211) provided on the first magnetic yoke (1212), and the second secondary unit (122) comprises a second magnetic yoke (1222) and a second magnetic steel (1221) provided on the second magnetic yoke (1222); the first magnetic yoke (1212) and the second magnetic yoke (1222) have a long axis arranged along a moving direction of a sliding base (132) and a short axis perpendicular to the long axis; the first magnetic steel (1211) is inclined relative to the short axis towards the moving direction of the sliding base (132), and the second magnetic steel (1221) is inclined relative to the short axis towards a direction facing away from the moving direction of the sliding base (132). The present technical solution solves the technical problem that a bending moment is generated between a rotor and a stator of a linear motor (10) due to the inclination of a magnetic steel, thereby affecting the performance of the motor.
