Direct Drive based Telescope for MASS-DIMM

Direct Drive Telescope for MASS-DIMM

This is the third instrument/project which I worked on as part of my Ph.D. The project goal was to develop a direct drive based telescope for the MASS_DIMM instrument. Lists of tasks I was involved in:-

Mechanical design of the telescope-interaction with the designer.
Design and fabrication of a direct drive axial flux motor.
Design and development of control electronics for the axial flux motor. Electronic boards like Encoder Interface boards, PIC microcontroller based controller, gate drive circuitry, MOSFET based drive electronics were developed.
Design of test setup for the ETEL motor (to be used in the telescope.
3D modelling of the telescope tube, and wind load analysis of the tube. Comparison study between the wind load on Tube type and truss type telescope optics.
