Description

Coil forming equipment for flat wire motor Technical Field The application relates to the technical field of coil processing, in particular to coil forming equipment for a flat wire motor. Background Currently, a flat wire motor is a motor that uses a flat wire (flat wire) instead of a conventional round wire as a winding conductor. The motor is similar to a common round wire motor in structural design and working principle, but has remarkable improvement in the aspects of performance, efficiency, power density and the like by virtue of the unique advantages of the flat wire, and is particularly suitable for the fields of high requirements of new energy automobiles, aerospace and the like. On the flat wire motor stator production line, coils can be inserted into stator core slots after being subjected to 2D molding and 3D molding in sequence. In traditional coil shaping production line, coil every time shaping processing is accomplished through a set of independent stamping die and actuating device, leads to the mould that needs the overall arrangement on the coil shaping processing line and actuating device's quantity too much, and then leads to coil shaping processing line overlength, and coil shaping processing production's cycle becomes long and manufacturing cost increases.
