The explanation is simple: the resolver consists only of metal parts (copper, stainless steel and Fe-Si) except the insulating materials in the stator which are all made of polyimide (Kapton). Since the insulation is the most sensitive to radiation, its choice determines the radiation resistance of the entire resolver.\u00a0Cf. CERN publications on the radiation resistance of insulating materials. Polyimide survives a maximal dose of 5*10^9 Rad\u00a0 or 5*10^7 Gy.<\/p>\n

Problem 1\u00b0<\/h2>\n

[\/vc_column_text][vc_column_text uncode_shortcode_id=”182378″]A major nuclear power plant had problems with prematurely failing surveillance resolvers\u00a0that were operating in a high radiation zone of the system.

The solution: Nuclear Monitoring Sensors by Admotec<\/h2>\n

[\/vc_column_text][vc_column_text uncode_shortcode_id=”170924″]Admotec engineers recommended the use of Rotasyn resolvers with radiation resistive insulation materials for monitoring angle and speed. The Rotasyn design has twice the MTBF (Mean Time Between Failures) compared to standard resolvers due to the lack of coils on the rotor, and is available with complete\u00a0radiation resistive insulation made from\u00a0polyimide. Due to the highly increased lifetime, the maintenance cost of the control systems of the power plant could be greatly reduced.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_single_image media=”113676″ media_lightbox=”yes” media_width_percent=”100″ uncode_shortcode_id=”119226″][\/vc_column_inner][\/vc_row_inner][vc_empty_space empty_h=”3″][vc_column_text text_color=”color-150441″ uncode_shortcode_id=”223099″ text_color_type=”uncode-palette”]<\/p>\n

Problem 2\u00b0<\/h2>\n

[\/vc_column_text][vc_column_text uncode_shortcode_id=”185608″]In order to measure the position of probes in the Large Hadron Collider (LHC) at the CERN institute in Geneva, an angular feedback system that is both hermetically enclosed and able to withstand high doses of radiation is needed.[\/vc_column_text][vc_empty_space empty_h=”3″ mobile_visibility=”yes”][vc_row_inner row_inner_height_percent=”0″ overlay_alpha=”50″ gutter_size=”3″ shift_y=”0″ z_index=”0″ inverted_device_order=”yes” limit_content=”” uncode_shortcode_id=”149564″][vc_column_inner width=”1\/2″][vc_single_image media=”113436″ media_lightbox=”yes” media_width_percent=”100″ uncode_shortcode_id=”195194″][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_empty_space empty_h=”3″ mobile_visibility=”yes”][vc_column_text text_color=”color-150441″ uncode_shortcode_id=”345374″ text_color_type=”uncode-palette”]<\/p>\n

The solution: Hermetic Rotasyn by Admotec<\/h2>\n

[\/vc_column_text][vc_column_text uncode_shortcode_id=”207528″]Admotec resolvers with their solid rotor allow a hermetic separation of the rotor and the stator and hence an encapsulated operation. Since the insulation of the stator is completely made from polyimide, the\u00a0resolvers are able to withstand extremely high radiation doses without compromising the functionality of the system. These two unique properties make Admotec resolvers perfectly suited for this high-end application.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_empty_space empty_h=”5″ mobile_visibility=”yes”][\/vc_column][\/vc_row][vc_row row_height_percent=”0″ overlay_alpha=”50″ gutter_size=”3″ column_width_percent=”100″ shift_y=”0″ z_index=”0″ uncode_shortcode_id=”178858″ back_color_type=”uncode-solid” back_color_solid=”#e0e0e0″][vc_column width=”1\/1″][vc_column_text uncode_shortcode_id=”119474″]<\/p>\n
