The former has  sinusoidal airgap flux and the back EMF, thus has  to be supplied with sinusoidal current to produce  constant torque. The PMBDCM has the trapezoidal  back EMF, so the rectangular current waveform in its armature winding is required to  obtain the low torque ripple. Generally, the  magnets with parallel magnetization are used in the  PMSM while the magnets with radial magnetization  are suitable for the BDCM. The interior PM (IPM)  synchronous machine is being studied as a promising  candidate for high-power starter\/alternator in  future internal combustion engine vehicles. The  other many popular applications of IPM machine are  traction, machine tool, spindle drives, air  conditioning compressors and electrical vehicles.  Torque ripple minimization in PM motors is  conventionally obtained by either good motor design  or appropriate control strategies. In design  optimization programs, a reliable and detailed  analysis of the torque and back-EMF of the machine  should be performed.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843392679\"\u003e\u003ch3\u003eOptimal Shape Design, Construction and Testing\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843392679","offer_id":39469958856797,"sku":"9783843392679","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/80f67cdd-1c30-43eb-9948-a0e22611bf26.jpg?v=1781932012","url":"https:\/\/shop.autorenwelt.de\/en\/products\/interior-permanent-magnet-synchronous-motors-von-arash-kiyoumarsi-und-rolf-hanitsch","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
