Craigh9916 Posted January 19, 2016 Report Share Posted January 19, 2016 Does anyone know if brushless motors work any better then brushed motors in the cold ? I'm asking as my brushless impact doesn't seem and different when it's really cold but my older brushed impact used to seem slower ! Now before you say it I know the main problem is the battery in the cold but putting that aside what do you lot think has anyone noticed there new brushless impacts not being affected as much as there older brushed ones ?

HiltiWpg Posted January 20, 2016 Report Share Posted January 20, 2016 The batteries would have more of an effect on cold weather performance. The type of grease can also be a factor. The different battery types also perform differently in colder weather. Lithium tends to be better in colder temps.Sent from my iPad using Tapatalk Quote Link to comment Share on other sites More sharing options...
Logan Posted January 20, 2016 Report Share Posted January 20, 2016 I have a bruched ni cad and they don't seem to be affected by the cold Quote Link to comment Share on other sites More sharing options...
JerryNY Posted January 20, 2016 Report Share Posted January 20, 2016 it should be more about battery chemistry than anything but I'd think a brushed tool might warm up faster in the cold. Quote Link to comment Share on other sites More sharing options...
kornomaniac Posted January 20, 2016 Report Share Posted January 20, 2016 The cells in more 'modern' lithium packs ( 4.0 amp + ) work better then the older generation lithium packs ( the 1.3 / 1.5 and 3.0 of old ! ). If you put an older 3.0 pack on that brushless impact i think you would notice a difference but that is because of the pack Quote Link to comment Share on other sites More sharing options...
Craigh9916 Posted January 20, 2016 Author Report Share Posted January 20, 2016 Like I said at the start putting batteries aside just going on motors only is there a difference in cold weather between a brushed motor and brushless as I am finding my brushless seems to work as normal whatever the weather but brushed seems to be little slower in the cold but have any of you lot noticed this ?Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Andrull Posted January 20, 2016 Report Share Posted January 20, 2016 Brushed and brushless motors have no real issues with cold. Most common electronics don't really have any large issues with cold either. It's as mentioned earlier everything else. Like the bearings, hammer/impact unit on impacts and battery cells that doesn't like it. Since they all depend on some kind of liquid.The slower bit could be many things. Like different grease, different reaction from the motor on more resistance or lower juice (voltage and current) from the batteries. An brushless unit have sensors that measures the RPM, and in general a lot smarter, and could counter the effects of the cold. Quote Link to comment Share on other sites More sharing options...
