But that is not what makes the ROSYNC so special. The developers achieved the outstanding efficiency through new materials and a special stator design. During development, the self-holding torque in the de-energised state was greatly reduced in favour of smooth running. Further advantages are the constant speed (independent of load and voltage), short start and stop times, low-vibration running and a compact design for limited space conditions. Because the better the efficiency, the smaller you can build.<\/p>\n<!-- \/wp:paragraph --><\/div>\n<!-- \/wp:column --><\/div>\n<p><!-- \/wp:columns --><!-- wp:paragraph --><\/p>\n<p>Assuming an electricity price of \u20ac0.23*, the results are as follows:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-bd098d5 elementor-widget elementor-widget-text-editor\" data-id=\"bd098d5\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<!-- wp:columns -->\n<div class=\"wp-block-columns\"><!-- wp:column -->\n<div class=\"wp-block-column\"><!-- wp:table {\"hasFixedLayout\":false} -->\n<figure class=\"wp-block-table\">\n<table>\n<tbody>\n<tr>\n<td>\u00a0<\/td>\n<td>Rosync<\/td>\n<td>Asynchronous motor<\/td>\n<td>Remarks<\/td>\n<\/tr>\n<tr>\n<td>Output power in W<\/td>\n<td>50<\/td>\n<td>50<\/td>\n<td>\u00a0<\/td>\n<\/tr>\n<tr>\n<td>Efficiency<\/td>\n<td>90%<\/td>\n<td>55%<\/td>\n<td>\u00a0<\/td>\n<\/tr>\n<tr>\n<td>Power consumption in W<\/td>\n<td>55<\/td>\n<td>90<\/td>\n<td>\u00a0<\/td>\n<\/tr>\n<tr>\n<td>Duty cycle per year<\/td>\n<td>8000 hrs.<\/td>\n<td>8000<\/td>\n<td>Three-shift operation<\/td>\n<\/tr>\n<tr>\n<td>Energy consumption per year in kWh<\/td>\n<td>440<\/td>\n<td>720<\/td>\n<td>Power consumption x hours \/ 1000<\/td>\n<\/tr>\n<tr>\n<td>Energy savings per year in kWh<\/td>\n<td>280<\/td>\n<td>\u00a0<\/td>\n<td>\u00a0<\/td>\n<\/tr>\n<tr>\n<td>Electricity costs per year in kWh<\/td>\n<td>101 \u20ac<\/td>\n<td>165 \u20ac<\/td>\n<td>Electricity price \u20ac 0.23<\/td>\n<\/tr>\n<tr>\n<td>Cost savings in 12 years<\/td>\n<td>750 \u20ac<\/td>\n<td>\u00a0<\/td>\n<td>\u00a0<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<figcaption class=\"wp-element-caption\"><span style=\"color: #ffffff;\"><strong>Sample calculation: Three-phase AC motors in use with conveyor belts<\/strong>, *Source: Electricity prices for commercial and industrial customers in Germany until 2021 - published by<\/span> <a href=\"https:\/\/de.statista.com\/statistik\/info\/unser-research-versprechen\">Statista Research Department<\/a>, <span style=\"color: #ffffff;\">01.04.2022<\/span><\/figcaption>\n<\/figure>\n<!-- \/wp:table --><\/div>\n<!-- \/wp:column --><\/div>\n<!-- \/wp:columns -->\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-444d0e2 elementor-widget elementor-widget-image\" data-id=\"444d0e2\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"500\" height=\"360\" src=\"https:\/\/www.rotek-motoren.de\/wp-content\/uploads\/2022\/05\/Rosync_Vergleich500_360.jpg\" class=\"attachment-large size-large wp-image-14229\" alt=\"Energiesparmotor ROSYNC im Vergleich mit SPG Motor\" srcset=\"https:\/\/www.rotek-motoren.de\/wp-content\/uploads\/2022\/05\/Rosync_Vergleich500_360.jpg 500w, https:\/\/www.rotek-motoren.de\/wp-content\/uploads\/2022\/05\/Rosync_Vergleich500_360-300x216.jpg 300w, https:\/\/www.rotek-motoren.de\/wp-content\/uploads\/2022\/05\/Rosync_Vergleich500_360-250x180.jpg 250w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">The photo shows the size comparison: a 40W three-phase AC motor from SPG (diameter 90 mm) and our Rosync motor with an output power of 50W (diameter 65 mm).<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a0474d3 elementor-widget elementor-widget-text-editor\" data-id=\"a0474d3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"wp-block-columns\">\n<div class=\"wp-block-column\">\n<p>Compared to conventional synchronous motors, the output power of the ROSYC is between +40 and +200 per cent for the same size. Its behaviour on the frequency converter is also outstanding thanks to its practically resonance-free operation from 1 - 70 Hz. Thanks to its compact design, it not only saves energy but also material. It is also maintenance-free and has a long service life. This solves several customer requirements at once. They save space and energy. They transmit a high torque. And they maintain safety.<\/p>\n<p>Thanks to the design, which is consistently focussed on material efficiency, the acquisition costs are at the usual market level for European quality motors. With an assumed service life of 12 years, the life cycle costs of a Rosync motor are more than a third lower than those of an asynchronous motor of comparable performance.

With an assumed service life of 12 years, the life cycle costs of a Rosync motor are more than a third lower than those of an asynchronous motor of comparable performance.<\/p>\n<p>The savings effect is particularly evident in applications with longer duty cycles, such as the conveyor belts mentioned above, screw conveyors in pellet heating systems or as drives in rotary heat exchangers. For example, replacing just 100 small motors in operation with motors from the Rosync series can reduce electricity costs by around 6000 euros every year, depending on the electricity price.<\/p>\n<\/div>\n<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-082b792 elementor-widget elementor-widget-image\" data-id=\"082b792\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"500\" height=\"360\" src=\"https:\/\/www.rotek-motoren.de\/wp-content\/uploads\/2022\/05\/rosync_fimatech_foerderbandantrieb_500_360.jpg\" class=\"attachment-large size-large wp-image-12733\" alt=\"Energiesparmotor ROSYNC als effizienter und platzsparender F\u00f6rderbandantrieb\" srcset=\"https:\/\/www.rotek-motoren.de\/wp-content\/uploads\/2022\/05\/rosync_fimatech_foerderbandantrieb_500_360.jpg 500w, https:\/\/www.rotek-motoren.de\/wp-content\/uploads\/2022\/05\/rosync_fimatech_foerderbandantrieb_500_360-300x216.jpg 300w, https:\/\/www.rotek-motoren.de\/wp-content\/uploads\/2022\/05\/rosync_fimatech_foerderbandantrieb_500_360-250x180.jpg 250w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">ROSYNC as an efficient and space-saving conveyor belt drive<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e9baa64 elementor-widget elementor-widget-text-editor\" data-id=\"e9baa64\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"wp-block-columns\">\n<div class=\"wp-block-column\">\n<p>The Rosync also demonstrates in an exemplary manner how climate-damaging CO<sub>2 <\/sub>emissions can be reduced through consistent product design.
