A relatively new concept is the use of a magnet system consisting of various types of magnets on one rotor, for example sintered and bonded magnets. This concept has been applied to the design and manufacture of the four-pole rotor of a synchronous motor with 400 W power and a rotational speed of 1500 rpm. In this motor, the stator of an asynchronous motor type Sh 71-4B is applied. The application of the new construction of the rotor resulted in an increase in motor efficiency and power factor compared to an asynchronous motor with the same volume.<\/jats:p>","DOI":"10.3390\/s140712425","type":"journal-article","created":{"date-parts":[[2014,7,10]],"date-time":"2014-07-10T11:22:59Z","timestamp":1404991379000},"page":"12425-12436","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Synchronous Motor with Hybrid Permanent Magnets on  the Rotor"],"prefix":"10.3390","volume":"14","author":[{"given":"Barbara","family":"Slusarek","sequence":"first","affiliation":[{"name":"Tele and Radio Research Institute, 11 Ratuszowa St., 03-450 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dariusz","family":"Kapelski","sequence":"additional","affiliation":[{"name":"Tele and Radio Research Institute, 11 Ratuszowa St., 03-450 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ludwik","family":"Antal","sequence":"additional","affiliation":[{"name":"Wroclaw University of Technology, 27 Wybrzeze Wyspianskiego St., 50-370 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pawel","family":"Zalas","sequence":"additional","affiliation":[{"name":"Wroclaw University of Technology, 27 Wybrzeze Wyspianskiego St., 50-370 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maciej","family":"Gwo\u017adziewicz","sequence":"additional","affiliation":[{"name":"Wroclaw University of Technology, 27 Wybrzeze Wyspianskiego St., 50-370 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2014,7,10]]},"reference":[{"key":"ref_1","first-page":"16","article-title":"Powder magnetic materials","volume":"R.86 Nr 4","author":"Slusarek","year":"2010","journal-title":"Przegl\u0105d Elektrotech."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"18","DOI":"10.1016\/S0026-0657(09)70170-5","article-title":"New PM magnetic development","volume":"64","author":"Slusarek","year":"2009","journal-title":"Metal Powder Rep."},{"key":"ref_3","first-page":"173","article-title":"Soft and synchronous starting of low-power SMPMSM motor","volume":"R.89 Nr 2b","author":"Antal","year":"2013","journal-title":"Przegl\u0105d Elektrotech."},{"key":"ref_4","first-page":"135","article-title":"Influence of the rotor construction on the single-phase line start permanent magnet synchronous motor performances","volume":"R.87 Nr 11","author":"Zawilak","year":"2011","journal-title":"Przegl\u0105d Elektrotech."},{"key":"ref_5","doi-asserted-by":"crossref","first-page":"1555","DOI":"10.1109\/28.887206","article-title":"The design of high efficiency line start motors","volume":"36","author":"Knight","year":"2000","journal-title":"IEEE Trans.
