Just crunching through the number on the first site. Not believing the power factor that I back calculated. Need a measured current at load. Not the motor must be run above synchronous by about the same speed as difference for the motor.

10 W 110 VAC .7 Amp AC 50Hz

1350 rev/min 10W/110V/0.7A = power factor 0.13

Active power 10W * 0.13 = 1.3W

reactive power sqr(10^2 -1.3^2) = 9.915W

Capacitive current Ic = 9.915W/110V = 0.09 amp

Capacitive reactance Xc = 110V/0.09A = 1222 ohms

Minimum capacitance C = 2*pi*50Hz*1222ohm = 383900 microF

16 W 110 vac 0.9 Amp AC 50hz

1300 rev/min 16W/110V/0.9A = power factor 0.16

Active power 16W * 0.16 = 2.56W

reactive power sqr(16^2-2.56^2)= 15.79W

Capacitive current Ic = 15.79W/110V = 0.1435 amp

Capacitive reactance Xc = 110V/0.1435A = 766.5 ohms

Minimum capacitance C = 2*pi*50Hz*766.5ohm = 240803 microF

40 W 220 vac 0.41 amp AC 50hz

2740 rev/min 40W/220/0.41A = power factor 0.44

Active power 40W * 0.44 = 17.6W

reactive power sqr(40^2-17.6^2) = 35.92W

Capacitive current Ic = 35.92W/220V = 0.163 amp

Capacitive reactance Xc = 220V/0.163A = 13459.7 ohms

Minimum capacitance C = 2*pi*50Hz*13459.7 ohm = 4228489.5 microF
