Latest Patents

Eric-G Lean holds a patent for a spindle motor designed specifically for optical disc drives. This spindle motor is a brushless motor of a single-phase axial-winding and radial-gap type. It includes a stator, a rotor coupled to the stator, and a driving circuit that supplies a driving signal to the stator to rotate the rotor. The stator features a pair of upper and bottom salient-pole pieces, which are formed with multiple tooth-like portions serving as salient-poles. The peak surface of each tooth-like portion is designed into a symmetrical convex shape, minimizing the cogging torque of the motor. Additionally, the use of a phase-adjuster in the driving circuit allows the motor to produce large output torque at high speeds. The output characteristics of this spindle motor meet the requirements of high-speed CD-ROM drives.
