How do brushless exciters work

WebOct 6, 2009 · "A brushless ac exciter works the same way as the main generator" OK but a generator increases it's power output by an increase in mechanical input. A brushless exciter increases the field current from power elsewhere. Clearly 15A and say 100V on the exciter can't result in 1500A and 1000V on the generator field without some other power … WebAug 20, 2024 · And although a brushless motor is better than its brushed counterpart, it doesn't mean a brushed motor is bad. In fact, a brushed motor is plenty good. You can achieve the same tasks with a brushed motor as people would with a brushless one. In general, brushless motors are the ideal motors inside your tools and equipment.
