PM synchronous motors are an alternative particularly to asynchronous machines concerning special applications. They stand out due to a number of advantages. Higher efficiency and a more compact design are a clear asset over restrictions in potential operating ranges. Especially the sensitivity of PM magnets regarding temperature, mechanical shock and flawed current supply of stator winding need to be highlighted.<\/p>\n
ELIN Motors globally deliver PM synchronous machines according to customer specifications in various designs and performance levels, amongst others, to the following industry fields:<\/p>\n<\/div>\n
As a\u00a0globally operating specialist for electric machines<\/strong>, ELIN Motors is your perfect partner for synchronous motors in any design and size.<\/p>\n<\/div>\n<\/div>\n <\/div>\n <\/div>\n<\/div>\n<\/div><\/div>\n\n Surface magnets can be attached to the rotor via bonding techniques. Additional bindings generate further stabilization.<\/p>\n Implementing this design, the rotor carries the magnets below the rotor surface according to their recess. Due to the newly accumulated space, the magnets can be adjusted advantageously. As a result, the field weakening area can be used more efficiently.<\/p>\n This winding system is suitable for all types of induction machines. Most-widely implemeted are distributed windings as two-layer windings for polyphase voltage systems.<\/p>\n The advantage of this design lies in the winding head\u2019s compactness. Due to the shorter winding head and the higher line density of a PM synchronous machine, the required space for the drive can be further reduced.<\/p>\n The operating principle of any electric machine is defined by the reciprocal repelling of the magnetic fields of stator and rotor. In case of the PM synchronous machine, the permanent magnets in the rotor create a field. The power distribution in the stator winding generates itself again a corresponding magnetic rotating field repelling the rotor.<\/p>\n The most vital components of PM synchronous motors are:<\/p>\n Only the machine\u2019s cooling system ensures the operating point in the required heating phase.<\/p>\n In the following you can find an example of the applied cooling systems:\u00a0<\/strong><\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":11,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"inline_featured_image":false,"footnotes":""},"acf":[],"yoast_head":"\nSurface Magnets<\/h3>\n
