Title

(EN) LINEAR VARIABLE DIFFERENTIAL TRANSFORMER WITH COMPLIMENTARY STEP-WINDING SECONDARY COILS
(FR) TRANSFORMATEUR DIFFÉRENTIEL LINÉAIRE VARIABLE COMPORTANT DES BOBINES SECONDAIRES DE BOBINAGES À PAS COMPLÉMENTAIRES

Abstract:

(EN)A linear variable differential transformer comprising a coil form; a first primary coil; an optional second primary coil; a first secondary coil; and a second secondary coil; wherein the windings of the secondary coils create complimentary and preferably uniform steps. Each step is preferably wound in at least two layers. In the embodiment comprising two primary coils, the inductive couplings between the primary and secondary coils cause null position to be physically centered within the transformer.
(FR)L'invention concerne un transformateur différentiel linéaire variable qui comprend une forme de bobine ; une première bobine primaire ; une deuxième bobine primaire facultative; une première bobine secondaire ; et une deuxième bobine secondaire. Les bobinages des bobines secondaires produisent de pas complémentaires et de préférence uniformes. Chaque pas est de préférence enroulé de manière à former au moins deux couches. Dans la forme de réalisation comprenant deux bobines primaires, les couplages inductifs entre les bobines primaire(s) et secondaires font en sorte que la position zéro est centrée physiquement dans le transformateur.
