1. A magnetic alignment system, comprising:

  • a magnet array configured to produce a magnetic field;

    a motor rotor disposed over the magnet array, wherein;

    the motor rotor comprises four coil assemblies arranged in a matrix, and among each two adjacent ones of the four coil assemblies, one is oriented along a first direction and the other is oriented along a second direction perpendicular to the first direction;

    a fixed tooling fixed in position with respect to the magnet array; and

    a force sensor unit connected between the motor rotor and the fixed tooling, wherein the force sensor unit is configured to, in the event of one of the four coil assemblies being supplied with a three-phase current, measure a force generated by the one of the four coil assemblies under an effect of the magnetic field.
