The invention provides a high-magnetoconductivity clutch coil assembly comprising an iron core end cover (1), an iron core shell (2), a coil assembly (3), and epoxy resin (4). The high-magnetoconductivity clutch coil assembly is characterized in that a slope (2a) is arranged in the iron core shell (2). The high-magnetoconductivity clutch coil assembly is simple in structure and convenient to machine, efficient utilization of a magnetic circuit is achieved in the effective space range, thus the clutch torque is increased under the premise of not changing the diameter of the iron core shell, andthe performance of the clutch is improved.
