In this paper there is studied the dynamic regime behaviour of a reluctance synchronous motor fitted out with a starting cage. There are analyzed two concrete situations: cage made of aluminium and cage made of copper. There are presented the mathematical model of the motor, the simulation program and the simulations carried out for the two situations. For the case of cage made of aluminium there have been performed experimental tests for direct-on-line no-load starting, tests that confirm the simulations carried out. The paper ends with conclusions regarding the influence of the cage material upon the time- dependent variation of the main electrical and mechanical quantities of the motor.
