A team of Engineers at Carlo Gavazzi has teamed up with researchers at the University of Malta to come up with HDMS – A High Dynamic Motor Starter which starts single phase motors – widely used in air-conditioning and pumps – that eliminates the need of a start capacitor whilst still starting with less than 1.2 times the motor’s nominal current. This innovation was made possible with an investment of €200,000 through the R&I Fusion Fund which is administered by the Malta Council for Science and Technology.
The results of HDMS were disseminated during a half day Public Engagement event held at the Chaplain’s Hall at the EsploraPlanetarium Building, Kalkara.
During his address, the Minister for Equality, Research and Innovation the Hon. Owen Bonnici said, “The Government is committed to keep investing in research and innovation and I would also like to encourage other private entities to consider investing in research and innovation because they are indeed our future.”
“Without such collaborations,” Minister Bonnici continued, “These Research and Innovation projects would be impossible and I cannot stress enough the importance for our country to keep investing in the strengthening of the research and innovation pillar which is the key for our economic growth and competitive impact.”
In his opening remarks, Executive Chairman Dr Jeffrey Pullicino Orlando said that: “Malta’s manufacturing industry is an important component of the Maltese economy and it is inspiring to see tangible results, including those achieved by the HDMS project consortium. The long-term goal is to strengthen and expand Malta’s high-value manufacturing cluster by developing an international standing not only as a production base, but also as a testing ground for innovation. The Malta Council for Science and Technology, in its public capacity, strives to foster a social ethos driven by research and innovation so that this sector continues to contribute to the economic growth of our country. This is achieved through FUSION, the Council’s portfolio of funding programmes, where researchers and their unremitting pursuit of innovative ideas come to fruition and make a valuable contribution to the sustainability of the local economy.”
The Project leadear of HDMS Inġ. Jason Demicoli said “HDMS was a great journey of cooperation between Industry and Academia, bringing innovation to the market! Starting by understanding the pain of our customers, we embarked on a challenging project based on our engineers’ competence, to develop and successfully launch an innovative fully patented Single Phase Soft starter”.
Typically single phase induction motors and compressors such as those used in heat pumps, water pumping and marine air-conditioning are problematic as during the start of these motors the large inrush current can reach levels of five to seven times the motor nominal current causing disturbance to the electrical grid or voltage sensitive equipment. The disturbance can cause voltage dips that can result in flickering of lights but can also disturb the operation of neighbouring equipment. Within off-grid installations (generator of PV) there might simply not be enough power to sustain this peak current and the generator or PV inverter might trip. To reduce this effect motor soft starting devices have been developed on the market, however these usally have a short lifetime since they all require a start capacitor to generate the required starting torque. Start capacitors are the weakest link in single phase soft starters and they tend to be the first components to fail as they are very senstive to high temperature and voltage fluctuations.
The HDMS innovation, overcomes both issues of high starting current as well as the short start capacitor lifetime. In fact, field appication tests have shown that HDMS can start single phase motors with a 60 – 70% less current surge compared to a direct start. This innovation brings with it a number of benefits. Appliances will have a longer lifetime, it will bring less disturbance to the eletrical grid, easy integration with off grid powered motor applications, savings on lower maintance hence less machine stoppages and increase in the share of renewable energy sources which are included in the EU Renewable Engergy Sources directive.

Innovazzjoni lokali żviluppata biex ċerta tipi ta’ apparat domestiċi ikollhom ħajja itwal mingħajr il-bżonn li jintuża start capacitor f’muturi single phase
Tim ta’ inġiniera mill-kumpanija Carlo Gavazzi ingħaqdu ma’ riċerkaturi mill-Fakultà tal-Inġinerija mill-Università ta’ Malta sabiex ikkrejaw HDMS – High Dynamic Motor Starter. L-innovazzjoni ta’ dan il-prodott elettroniku hi li kapaċi jixgħel kumpressuri u pompi mingħajr l-użu ta’ start capacitor filwaqt li jnaqqas l-impatt fuq il-vultaġġ peress li jwaqqa’ l-kurrent tal-mutur għal-madwar 1.2 darba il-kurrent nominali tal-mutur. Din l-innovazzjoni kienet possibbli permezz ta’ investiment ta’ €200,000 mill-Fond FUSION tal- R & I amminstrat mill-Kunsill Malti għax-Xjenza u t-Teknoloġija.
Ir-riżultati ta’ HDMS ġew imħabbra waqt avveniment għall-pubbliku li seħħ fiċ-Chaplain’s Hall fil-binja tal-EsploraPlanetarium, il-Kalkara.
Waqt li ndirizza dawk presenti, l-Ministru għall-Ugwaljanza, ir-Riċerka u l-Innovazzjoni, l-Onor. Owen Bonnici qal, “Il-Gvern huwa kommess li jkompli jinvesti fir-riċerka u l-innovazzjoni, u nixtieq inħeġġeġ ukoll entitajiet privati sabiex jikkunsidraw li jinvestu fir-riċerka u l-innovazzjoni għaliex dawn huma tabilħaqq il-futur tagħna.”
Il-Ministru Bonnici kompla jgħid li, “Mingħajr kollaborazzjonijiet bħal dawn, dawn il-proġetti tar-Riċerka u l-Innovazzjoni jkunu impossibbli. Ma nistax nisħaq biżżejjed l-importanza li pajjiżna jibqa’ jinvesti u jsaħħaħ il-pilastru tar-riċerka u l-innovazzjoni, essenzjali fit-tkabbir ekonomiku u l-impatt kompetittiv.”
Iċ-Ċermen Eżekuttiv Dr Jeffrey Pullicino Orlando, fid-diskors tal-ftuħ tiegħu qal li: “L-industrija tal-manifattura f’Malta hija parti integrali tal-ekonomija Maltija u huwa inkoraġġanti li nkomplu naraw riżultati tanġibbli f’dan il-qasam, bħar-riżultati miksuba mill-konsorzju tal-proġett HDMS. L-għan aħħari huwa li nsaħħu u nwessgħu l-qasam tal-manifattura ta’ valur għoli billi niksbu reputazzjoni tajba fuq livell internazzjonali. Dan niksbuh billi nservu bħala bażi ta’ produzzjoni, kif ukoll billi noffru opportunitajiet biex innovazzjonijiet ġodda jiġu ttestjati hawn Malta. Il-Kunsill Malti għax-Xjenza u t-Teknoloġija, fil-responsabbiltà fdata lilu, jistinka sabiex irawwem fis-soċjetà kultura ta’ riċerka u innovazzjoni sabiex dan il-qasam ikompli jikkontirbwixxi għal tkabbir ekonomiku f’pajjiżna. Dan niksbuh permezz ta’ FUSION, il-portafoll ta’ programmi ta’ finanzjament tal-Kunsill, fejn l-ideat innovattivi tar-riċerkaturi jieħdu l-ħajja u jikkontribwixxu b’mod siewi għas-sostenibbiltà tal-ekonomija lokali.”
Il-mexxej tal-proġett HMDS l-Inġ Jason Demicoli qali li “HDMS kien vjaġġ fenomenali ta’ kooperazzjoni bejn l-Industrija u l-Akkademja, li wasslu l-innovazzjoni lejn is-suq! Dan billi fhimna dak li jgħaddu minnu l-klijenti tagħna, dħalna għal proġett ta’ sfida ibbażat fuq il-kompetenza tal-inġiniera, biex jiżviluppaw u jniedu innovazzjoni, protetta b’patent, ta’ Single Phase Soft starter.”
Tipikament muturi single phase u kumpressuri bħalma huma wżati f’heat pumps, pompi tal-ilma u air-conditioners li jintużaw fuq opri tal-baħar, joħolqu diffikultà meta jkunu qed jintxtegħlu. Dan minħabba l-fatt li jkun hemm kurrent qawwi f’salt li jista’ jilħaq sa aktar minn ħames sa seba’ darbiet aktar mill-kurrent nominali tal-mutur b’konsegwanza li jista’ jikkawża effetti negattivi fil-grid tal-elettriku jew f’apparat li jkun sensittiv għal żbilanc fil-vultaġġ. Dan it-tfixkil jista’ jikkawża tnaqqis fil-vultaġġ u teptip tad-dawl kif ukoll jista’ joħloq ħsarat f’ċerta tagħmir elettroniku fl-istess installazzjoni. Fil-każ ta’ generators u panelli fotovoltajiċi jista’ jkun li s-saħħa ma tkunx biżżejjed biex tipprovdi l-kurrent u l-vultaġġ neċessarju u l-generators u l-PVs, jistgħu anke jieqfu jaħdmu temporanjament. Sabiex jitnaqqas dan ir-riskju fis-suq jeżistu prodotti elettronici magħrufa bħala soft starters. Soft starters li jintużaw fuq single phase, ġeneralment ikollhom bżonn ta’ start capacitor biex jiġġenera s-saħħa meħtieġa biex jinxtegħel it-tagħmir. L-istart capacitors huma komponenti sensittivi ħafna għal żbilanc fil-vultaġġ kif ukoll għat-temperaturi għolja u tipikament huma l-ewwel komponenti li jfallu.
Din l-innovazzjoni tal-HDMS tegħleb dawn l-isfidi ta’ influss ta’ kurrent għoli fil-mument li jinxtegħel apparat induttiv bħal muturi, kif ukoll il-problema tal-ħajja qasira tal-capacitor. Fil-fatt, studji urew li HDMS jista’ jixgħel muturi single phase b’influss ta’ kurrent bejn 60 – 70% inqas minn meta jinxtegħel b’mod dirett. Din l-innovazzjoni għandha ħafna benefiċċji
fosthom li l-apparat jista’ jkollu ħajja itwal, se jkun hemm inqas tfixkil mal-grid tal-elettriku, se tintegra aħjar mal-apparat bħal generators u panelli fotovoltajiċi, se jkun hemm inqas manutenzjoni riżultat ta’ inqas ħsarat u żieda fis-sehem ta’ sorsi ta’ enerġija rinnovabbli li huma inklużi fid-direttiva tal-UE dwar Sorsi u Enerġija Rinnovabbli.
