VIEGO FELIPE, Percy Rafael; GOMEZ SARDUY, Julio Rafael  e  PADRON PADRON, Enrique Arturo. New syncronous high-efficiency motors. Universidad y Sociedad [online]. 2020, vol.12, n.2, pp. 205-211.  Epub 02-Abr-2020. ISSN 2218-3620.

A basic comparative study on construction characteristics, fundamental parameters and some applications of high efficiency synchronous motors without windings in the rotor was carried out. These are, for variable speed loads driven by variable frequency drives, synchronous reluctance motors and synchronous reluctance assisted by permanent magnet. For constant loads with direct start to the line, reluctance and reluctance assisted by permanent magnet were developed. The latter was studied briefly. A case study with economic analysis was conducted for a Cuban company, demonstrating substantial savings compared to the use of a high efficiency asynchronous motor.

Palavras-chave : High-efficiency electric motors; synchronous reluctance motors; direct-on-line-start; permanent magnets; rare earths or ferrites; economic analysis.
