The '''reactances of synchronous machines''' is a set of characteristic constants used in the theory of [[synchronous machine]]s.{{sfn|Park|Robertson|1928|p=514}} Technically, these constants specified int units of the [[electrical reactance]], although they are typically expressed in the [[per-unit system]] and thus [[dimensionless]].

Das{{sfn|Das|2017|pp=180-182}} identifies the following reactances:

* leakage reactance <math>X_l</math>;

* subtransient reactance <math>X''_d</math> with the quadrature-axis counterpart;

* transient reactance <math>X'_d</math>;

* synchronous reactance <math>X_d</math>;

* quadrature axis reactances <math>X_q</math>, <math>X'_q</math>, <math>X''_q</math>, counterparts to <math>X_d</math>, <math>X'_d</math>, <math>X''_d</math>;

* negative sequence reactance <math>X_2</math>;

* zero sequence reactance <math>X_0</math>;

* Potier reactance <math>X_P</math>.
