DIGITAL ELECTRIC POWER DRIVES FOR NEW GENERATION QUANTUM OPTICAL SYSTEMS

SKU0064

DESCRIPTION

The power electric drive is intended for pointing of quantum-optical systems of new generation. The device has:

high positioning precision.
smoothness of motion within the speed ranges from zero to tenths of degrees.
broadband dynamic flexibility essential for minimization of environmental perturbations.

Thanks to the use of a gearless electric drive based on torque motors and high-precision optical angle sensors, ITMO researchers developed guidance systems for optical telescopes that correspond to the international requirements and provide for a pointing accuracy on the level of arcseconds.

The research is conducted by ITMO University on the order of JSC High Precision Systems (main customers: ROSCOSMOS, The Ministry of Defense of the Russian Federation).

ADVANTAGES OF THE DEVELOPMENT

Works with precision absolute optical sensors via the BISS interface.
Elimination of the stepwise motion pattern of the tracking axis at infralow speeds.
A wide range of tracking speeds (18000) at small mean squared error values that call for a high Q factor in the system speed (from 200 to 2000).

CHARACTERISTICS

Maximum axis rotation speed: up to 100 °/s
Maximum axis rotation acceleration: up to 100 °/s2
Moments of inertia of rotating parts: from units to tens of thousands kg-m2
Data exchange via CAN-interface
Mean squared error at the speed of 0...5 °/s: no more than 1”
