Abstract:
A three-axis voice coil motor including a base, a spherical bearing, a magnetic component, an X-coil group, a Y-coil group, and at least one Z-coil group is provided. The base has a supporting pole. The spherical bearing is rotatably sleeved around the supporting pole. The magnetic component is securely sleeved around the spherical bearing and the magnetic component rotates along with the spherical bearing. The X-coil group is disposed around the magnetic component along an X-axial direction passing through the spherical bearing, and the X-coil group has first gaps. The Y-coil group is disposed around the magnetic component along a Y-axial direction passing through the spherical bearing, and the Y-coil group has second gaps. The Z-coil group is disposed around the magnetic component along a Z-axial direction passing through the spherical bearing.
