[CN 201810308295.7] Stator permanent magnet linear motor drive press
[CN 201810308295.7] Title of a stator permanent magnet linear motor drive press: Application number of a stator permanent magnet linear motor drive press: CN 201810308295.7 Applicant: xidian university Application Date: 2018-4-8 Patent Type: Invention Application The present invention discloses a stator permanent magnet linear motor drive press, including a punch, a motor secondary core, a motor primary, a body side plate, a base, a balance cylinder, etc; four identical stator permanent magnet linear motors are symmetrically arranged between the four sides of the punch and the body side plate; each stator permanent magnet linear motor includes a motor primary and a motor secondary core, and the motor secondary core is directly arranged on the punch On the side of the motor; the outside of each motor secondary core is provided with a motor primary; the motor primary consists of a multi-tooth primary core, permanent magnets, armature windings and a primary bottom plate; the multi-tooth primary iron core is arranged on the primary base plate in a vertical direction, and the permanent magnets are placed on both sides of each multi-tooth primary iron core at intervals; the three-phase armature windings are sequentially wound in the phase sequence of A- Z-B-X-C-Y In the multi-tooth primary iron core slot. The overall structure of the press of the invention is simple and compact, the stamping force driven by multiple motors is large, and the controllability is strong, which meets the development requirements of high-speed, high-efficiency, precise and reliable presses.
