Title (EN) ELECTRIC PERMANENT MAGNET CHUCK
(FR) MANDRIN À AIMANT PERMANENT ÉLECTRIQUE
(ZH) 一种电永磁吸盘
Abstract:
(EN) An electric permanent magnet chuck, comprising a casing (1), the casing being provided thereon with at least one open inner cavity; reversible magnetic steel (2) is provided at a lower portion of the inner cavity, and a coil (3) is arranged in the inner cavity along an outer wall of the reversible magnetic steel; a magnetic pole (4) is superposed and fixed in the inner cavity, an annular groove being provided at a lower surface of the magnetic pole, and permanent magnet steel (5) that matches the annular groove being disposed in the annular groove. The electric permanent magnet chuck has the advantages of a simple structure, low processing difficulty, good sealing performance, small magnetic loss and so on.
(FR) Un mandrin à aimant permanent électrique, comprenant un boîtier (1), le boîtier comportant au moins une cavité interne ouverte; un acier magnétique réversible (2) est disposé au niveau d'une partie inférieure de la cavité interne, et une bobine (3) est disposée dans la cavité interne le long d'une paroi externe de l'acier magnétique réversible; un pôle magnétique (4) est superposé et fixé dans la cavité interne, une rainure annulaire étant disposée au niveau d'une surface inférieure du pôle magnétique et de l'acier à aimant permanent (5) qui correspond à la rainure annulaire étant disposé dans la rainure annulaire. Le mandrin à aimant permanent électrique présente les avantages d'une structure simple, d'une faible difficulté de traitement, d'une bonne performance d'étanchéité, d'une petite perte magnétique, etc.
(ZH) 一种电永磁吸盘包括壳体(1),壳体上设有至少一个敞开式内腔,内腔下部设有可逆磁钢(2),内腔中沿着可逆磁钢的外壁设置有线圈(3)。在内腔中叠加固定有磁极(4),在磁极的下表面设置有环形凹槽,在环形凹槽中设置有与环形凹槽相配合的永磁钢(5)。这种电永磁吸盘具有结构简单、加工难度小、密封性好和磁力损失小等优点。
