WebApr 13, 2024 · The central component of the model is the voltage equation with the corresponding resistances R, leakage inductances L, and inductances M. The voltages and currents of the three stator phases and and the rotor loops and are considered individually. WebIdeally, neglecting losses, the fully-controlled bridge d.c. voltage sets the speed to which the motor will accelerate. Control is therefore very similar to a d.c. drive. Power can flow in only one direction via the diode bridge which means that motoring torque can be developed only at subsynchronous speeds. meditec pharma https://skayhuston.com
