The equivalent circuit of a single phase induction motor is shown in the figure, where the parameters are Xl1 = Xl2 = 2 Ω, R1 = R2 = 2 Ω, XM = 240 Ω and s is the slip. [cite: 115] At no-load, the motor speed can be approximated to be the synchronous speed. [cite: 116, 117] The no-load lagging power factor of the motor is___________ (up to 3 decimal places).
