Title (EN) MOTOR LAMINATION MITIGATING TORQUE CONSTANT ROLL OFF
(FR) STRATIFICATION DE MOTEUR ATTÉNUANT LE GLISSEMENT CONSTANT DU COUPLE
Abstract:
(EN) A straight line lamination for an electric motor has alternating finger segments and hinge segments to be rollable after windings are installed to form a circular motor stator. The lamination is configured such that inner edges of a back iron region are non-arcuate in shape to provide extra back iron material near the hinge segments for mitigating torque constant roll off.
(FR) L'invention concerne une stratification en ligne droite destinée à un moteur électrique et présentant une alternance de segments formant doigts et de segments d'articulation pour pouvoir rouler après l'installation d'enroulements de manière à former un stator de moteur circulaire. La stratification est conçue de sorte que des bords internes d'une région de fer arrière soient de forme non arquée pour fournir un matériau de fer arrière supplémentaire près des segments d'articulation afin d'atténuer le glissement constant du couple.
