- In this video, we'll review the causes of motor overload, the differences of electrical and mechanical overload, the devices used in solving motor over-exertion, single phase motors, motor warranty, primary symptoms, nuisance tripping, preventing future overload, finding new motors, overload devices (such as the overload relay and variable frequency drive) and more.
If your motors fail often, are losing a large percentage of efficiency, or are over-exerting themselves constantly, you may find this video useful. We'll guide you through the process of preventing future motor overload and ways to check if your motor is overloading.

Great advice
nice statment
Thanks Hemin - more videos coming soon.
Thankyou sir
I have a motor with Furnas relay coil, and H12 heating elements, I always have to reset the relay can't figure the problem and the motor current is in range on the motor data plate.
Hi Avis, great question.
Are you referring to the starter or the relay? A starter is a relay combined with an overload. As these devices age, the overload can become more sensitive and the overcurrent point tends to drift lower. This can cause premature trips. I recommend checking if you have a variable overload, in which case, you may be able to set it a little higher in order to prevent the trips.
Alternatively we offer magnetic starters from WEG and our technical support team that can help you size the overload appropriately to prevent trips.
I hope this helps!
excellent training! thanks
Thanks for watching JC!
Hi.
we are experiencing the current issue.
Motor is on a Soft Starter.
motor name plate 283.0 amps.
The motor is pulling over 10 amps in two phases .
input voltage is phase A= 279, phase B= 281, phase C= 282.
we megged the motor and cables they seems to be fine.
There is not loose connections .
there is no weird noises coming from the motor.
there is no high vibration.
motor spins freely and there is nothing jamming the shaft.
We do not understand why the current is high on two phases only.
What kind of test can tell us what the problem is ???.
Thanks.
It sounds like it could be phase loss but I'm not sure based on the information provided. Best bet is to take it into a local shop to troubleshoot.
I love the video
Thanks - more videos coming soon.
Good job
Thanks
I do have trail blazer 2016 I do have a problem with overload electricity they told me to change the alternator I changed it but still now the battery and I change it too but still having and showing overload electric on it now I need to know what I have to check or what part I have to check or replace it plz need your help by the way they check everything but still can't fine the problem
Hi Ahemd - sorry to hear about your car problems. My expertise is on the electric industrial motor side - you may be better off to work with a dealership or auto expert on this one.
The VFD has already overload protection for the motor? do we really need an another overload protection device?
Hi Mark, yes, VFDs provide overload protection. The internal overload protection needs to be set correctly according to the rules set out by the local electrical code since the drive may be rated for more amps than the motor is. The decision to add external overload protection depends on local electrical code and if the VFD being used is compliant with local standards. Thanks for the question!
