Hi there,
Can anyone help to shed some light about the so called three phase induction motor energy saver which allegedly can save the energy consumption of the motor by as much as 25%. My employer requested the feasibility study. Pity the claimant doesn’t want to disclose the principle of operation and also they don’t want to disclose the variables which I should measure to notice the effects, they just say it works.. Please help
Regards,

RE: Hi there, Can anyone help to shed
There's another active type saver the supposedly monitors the power factor and reduces/increases voltage when needed.
The best thing to do is to size your motor for the application; make sure your running at at least 3/4 load.
RE: Hi there, Can anyone help to shed
In some instance, the efficient of a motor could be increased if the motor is rebuild.
SUGGESTION: Check with DOE and other organizations for guide, publications and software available.

Search on “motor energy saver” at this site. Similar devices have been discussed here.
RE: Hi there, Can anyone help to shed
Verification is very simple, have him/her hook up one of his/her 'demo' or test product (at no charge of course) to one of your motors and setup kW and amp meters. Take readings with and without the 'energy saver'. If you do not see any significant reduction in kW, (and only kW) do not fall for the product!
Reduction is kvA or pf is irrelavant, you do not need a 'energey saver' for that as there are other proven avenues for them.
baldor's suggestion is a good one to size the motor correctly.
Plus motor draws what it needs, so I am personally skeptical of such energy saver gismos.
