Article

Advancement in power electronics over the last few decades has made it possible to utilize a variety of rotating electric machines that would otherwise not be feasible. One such class of machines is called reluctance machines because of the way they produce an electromagnetic torque. A reluctance machine is an electric machine in which torque is produced by the tendency of its movable part to move to a position where the inductance of the excited winding is maximized.

Los avances en la electrónica de potencia en las últimas décadas han permitido el uso de una variedad de máquinas eléctricas rotativas que de otro modo no sería factible. Una de ellas se denomina máquina de reluctancia debido a la forma en la que dichas máquinas producen un torque electromagnético. Una máquina de reluctancia es una máquina eléctrica en la cual el torque se produce por la tendencia de su parte móvil a moverse a una posición donde se maximiza la inductancia del devanado excitado.

Service centers are seeing an increase in the number of SRMs received for repair, and some of the technicians encountering them are unfamiliar with how they work. As with any other rotating machine, a basic understanding of operating principles can be useful in troubleshooting and repair. One of the most critical things for service center personnel to understand upfront is that these machines cannot be operated without a special drive, which typically would need to be supplied by the end-user or the manufacturer.

Los centros de servicio están notando un incremento en el número de SRMs que reciben para reparar y algunos de los técnicos no están familiarizados con su funcionamiento. Como cualquier otra máquina rotativa, un conocimiento básico de los principios de funcionamiento puede ayudar a detectar problemas y durante la reparación. Uno de los puntos más críticos para el personal del centro de servicios es entender de antemano que estas máquinas no pueden ser operadas sin un drive especial, el cual normalmente necesita ser suministrado por el usuario final o el fabricante.

Article

One of the many interesting things we get to do as repairers of rotating electrical equipment is to rewind the rotating poles of synchronous machines. Handling large poles can present special challenges, but the actual winding process itself can be downright enjoyable—if we are adequately prepared. This article will outline procedures that take the mystery out of successful pole winding. The procedures are also helpful for stationary field coils and interpoles.
