You are asking about 50/60 Hz CFL ballast chokes? They act as constant current source and can work for you if the load has at least proportional (resistive) V/I characteristic or a stiffer characteristic towards constant V.

Hm... it is to power up a 240v shaded pole motor at hald the voltage (120v, draws 8W there)
The other thing I was thinking was a simple series diode. The diode will cut-off the negative portion of the AC cycle but not completely (0.6v drop) the resulting waveform will be a very distorted AC and the P2P voltage would be around half.
The motor nominal voltage is 240v. So can i connect the primary of a small transformer in series with the motor, to use this as a choke? The primary has some resistance so this might work?
