Abstract
A coil module comprises a circular core and a winding is provided. The circular core comprises an outer circular portion and an inner circular portion. The winding is wound around the outer circular portion in a single-layer configuration and around the inner circular portion in a multi-layer configuration. The coil module comprises a first thickness after the winding is wound around the outer circular portion and comprises a second thickness after the winding is wound around the inner circular portion, wherein the first thickness is greater than or equal to the second thickness.
Claims18
A coil module comprising:
- a circular core with a closed shape comprising an outer circular portion and an inner circular portion;
- and
- a winding being wound around the circular core, in which the winding is wound around the outer circular portion in a single-layer configuration, and the winding is wound around the inner circular portion in a multi-layer configuration;
- wherein the circular core is in compliance with a relationship of:
- (H1−H2)/2≧ΔL×Φ, in which H1 is a first height, H2 is a second height, the first height being greater than the second height, ΔL is a difference of the layer number of the winding wound around the outer circular portion and the inner circular portion, and Φ is a wire diameter of the winding.
