A method of manufacturing a compressed coil and a system for holding a wire during the manufacture of a compressed coil are disclosed. The method includes providing a wire including a first lead section, a central section and a second lead section. The central section of the wire is wound around a bobbin to form a coil. A punch top is located over an end of the bobbin such that the end of the bobbin is located at least partially within a through-hole of the punch top. A second lead section of the wire is located within a groove in an outer surface of the punch top or bobbin and pressure is applied to the bobbin and/or punch top to compress the coil.

This is the U.S. National Stage of International Application No. PCT/GB2015/052861, filed Sep. 30, 2015, which in turn claims the benefit of and priority to United Kingdom Application No. GB1417355.3, filed Oct. 1, 2014.
The present invention relates to a method and system for manufacture of a compressed coil. In particular, but not exclusively, the present invention relates to a method of compressing a coil whilst preserving the integrity of the coil terminations.
There is an increasing demand in the automotive and aerospace industry for high power density electrical machines. Such machines usually operate at high current densities and high speeds.
Embodiments of the invention are further described hereinafter with reference to the accompanying drawings, in which:
FIGS. 1a, 1b, 1c and 1d respectively illustrate a punch top, a bobbin, another view of the bobbin and a die;
FIG. 2 illustrates a bobbin with a wire wound about the bobbin;
In the drawings like reference numerals refer to like parts.
FIGS. 1a, 1b, 1c and 1d respectively illustrate an example of a punch top, a bobbin, the bobbin of FIG. 1c from another perspective, and a die used during a method of manufacturing a compressed coil.
In this example, the bobbin 101 includes a central portion (a spindle) 102 and a flange 103 located at a first end 104 of the spindle 102 (as shown in FIGS. 1b and 1c). The spindle 102 has a substantially rectangular cross-sectional shape and is of suitable length for a wire to be wound around the spindle to form a coil. The bobbin is formed from high strength tool steel material in this example.
