What is a Gauss Jordan elimination?

\[ s = \frac{N_s - N_r}{N_s} \]

where:

- \( N_s \) is the synchronous speed of the motor (in RPM),

- \( N_r \) is the rotor speed (in RPM).

Slip is expressed as a fraction or percentage and indicates how effectively the motor is converting electrical energy into mechanical energy. For example, a slip of 0.05 (or 5%) means that the rotor is rotating at 95% of the synchronous speed.
