  • Motor drive apparatus and control method for a surveying instrument
    Patent number: 8365424
    Abstract: A motor drive apparatus for a surveying instrument and a control method for controlling a surveying instrument enables a fast rotation of an instrument axis with high angular resolution. The motor drive apparatus for a surveying instrument includes a first motor for rotating an instrument axis. The first motor includes a stator and a rotor having a rotation axis and a plurality of step positions relative to the stator. The motor drive apparatus also includes a mounting unit for mounting the first motor so as to be pivotable around the rotation axis and an adjusting unit for rotating the stator of the first motor around the rotation axis.
