摘要
Certain example embodiments relate to torsion compensation coils that cooperate with primary coils in voice coil motors of disk drive devices, and methods of making the same. In certain example embodiments, a voice coil motor is provided which may include a single external magnet. A primary coil may be located above the external magnet, with the primary coil being capable of receiving a first current. At least one torsion compensation coil may be connected to the primary coil. The at least one torsion compensation coil may be capable of receiving a second current. The at least one torsion compensation coil may be configured to reduce torsion and/or bending forces introduced by the first current passing through primary coil and/or magnetic field leakage from the external magnet.
