Abstract: | Variants of excitation systems of low-speed synchronous machines with tangential and radial magnetization of permanent magnets are considered. Based on magnetic-field simulation using the finite-element method, different excitation systems are compared and the rotary-speed range is determined that should be preferred for one or another form of permanent magnets. |
