Abstract

A rotation detecting device includes a magnet, a first magnetic sensing assembly and a second magnetic sensing assembly. The magnet is rotatable about a rotation axis. As the magnet is rotated for one turn, a magnetic characteristic of the magnet is correspondingly changed for a cycle. The first magnetic sensing assembly is located over the magnet, wherein the rotation axis of the magnet passes through the first magnetic sensing assembly. A first lengthwise direction of the first magnetic sensing assembly is in parallel with a rotation radius direction of the magnet. The second magnetic sensing assembly is arranged beside the first magnetic sensing assembly. A second lengthwise direction of the second magnetic sensing assembly is in parallel with a rotation tangential direction of the magnet. An included angle between the second lengthwise direction and the first lengthwise direction is (90+θ) degrees, wherein −30≤θ≤30.
