1.0 INTRODUCTION

This manual covers the 2-tube radiographic and fluoroscopic configurations of the Rotor-AID LC100
Rotor Controller.

1.1 General Information


Rotor-AID LC100 Series Rotor Controllers provide the necessary control signals, interlocks and
power outputs to drive the anode rotors of x-ray tubes to near 3600 rpm (60Hz) or 10,800 rpm
(180Hz) and then to DC brake them. Both boost and brake are achieved in the shortest possible
time periods which are digitally preset for each individual tube.


Solid state logic and microprocessor control is provided to accommodate all common procedures
such as fluoroscopic, cine and spot film as well as radiographic, CT and digital.


IGBT inverters are used to accelerate the rotor to high speed. Line frequency is used to
accelerate or decelerate the rotor to low speed.


Current sensing is provided to monitor main and phase stator currents during boost and run
periods and to provide relay interlock contacts to prevent x-ray exposures if these currents are
not present.


Medium size anode tubes with heat storage capacities of up to 1 million heat units
can be rapidly accelerated to full speed.

2.0 SPECIFICATIONS


2.1 Control Interface Input Voltages


Factory/field selectable jumpers for each input circuit permit nominal input levels of 5VDC,
12VDC, 24VDC, or 120VAC for each input circuit (refer to Section 3.4a). Loading is
nominally 10mA for any input voltage selected.
