This equipment serves as the initial station in a flat-wire stator production line, designed to automatically insert insulating paper into the slots of a stator core, thereby establishing slot insulation. The machine is compatible with O-type, B-type, S-type, and C-type insulating papers, and supports both "cold insertion" and "hot insertion" processes. It features an insertion precision of ±0.1 mm, a single-slot cycle time of ≤1 second, and a maximum insertion height of 300 mm. The dual-station design enhances efficiency, while integrated dust extraction and real-time temperature monitoring functions ensure that the paper insertion process is free of damage. The insulation withstand voltage exceeds 5000V. With a modular design for model changeovers and mirror-polished paper feed channels, the machine enables rapid reconfiguration without causing damage to the paper.
Suitable for the insertion of insulating paper into the stator core slots of flat-wire drive motors for new energy vehicles. It accommodates both composite and pure paper materials, and is compatible with O, B, S, and C paper types. The cold insertion mode is suitable for standard insulating papers, while the hot insertion mode is ideal for thicker or more rigid insulating papers. Within the production line, this station is positioned downstream of the stator core loading station and upstream of the coil insertion machine. The equipment supports insertion heights of up to 300 mm and accommodates stators with varying slot counts (ranging from 48 to 108 slots).
Automatic paper feeding, bending/forming, and insertion into stator slots; support for switching between O/B/S/C paper types; selectable cold/hot insertion modes (with real-time temperature monitoring for hot insertion); alternating operation via a dual-station configuration; dust extraction system for clearing paper debris; post-insertion inspection to ensure zero damage; and modular design for rapid model changeovers.
