A set of primary schemes for astronomical applications  including the altitude axes being driven by 2 DC torque motors  the azimuth by 4 DC torque motors using helical gears  and two pieces of the 27-bit segment tape encoders for each set of axes is proposed. To meet practical engineering needs  the shafting motion parameters are designed and motor elementary parameters are primarily calculated to offer the important references for further study on system driving model and prototype development.
