COIL UNIT AND COIL ASSEMBLY FOR IRON-LESS LINEAR MOTOR

摘要

A coil unit and coil assembly for iron-less liar motor and the coil unit includes two vertical function sides and two axial non-function sides. The multiple units are alternatively connected to each other by inserting the vertical function side of one coil unit into the hollow portion of the adjacent coil unit so as to form a coil assembly. The width of the vertical function side is D1 and the distance between two respective insides of the two vertical function sides is D2. D2=m×D1+ΔL, wherein m representing the number of the vertical function sides of other coil units received in the vertical direction of the hollow portion. The ΔL is the width of the gap which receives a separation plate between the two adjacent vertical function sides to increase the efficiency of dissipating heat or insulation when current passes through the coil assembly.

1. A coil unit comprising:
an insulation wire bent continuously to form a loop which encloses a hollow portion, the coil unit having two vertical function sides and two axial non-function sides, a bent section formed adjacent to each of the two axial non-function sides so as to alternatively arrange the multiple coil units by inserting the vertical function side of one coil unit into the hollow portion of the adjacent coil unit, the coil unit having two side areas, a width D1 of the vertical function side being defined from the side area corresponding to the vertical function side, a distance between two respective insides of the two vertical function sides being defined as D2, D2=m×D1+ΔL, wherein m represents a number of the vertical function sides of other coil units received in a vertical direction of the hollow portion, ΔL being a width of a gap which receives a separation plate between at least two adjacent vertical function sides.
