October 5th, 2020 12:13 AM #202Brushless are for DC battery operated.
I have yet to see a brushless corded power tools. Most corded are brushed AC driven, they have more torque than brushless.

your inverter a/c is actually a brushless motor. the inverter is fed DC that's converted from 220v AC there's a lot of electronics to accomplish that. power tools need to be compact and robust so they're fine just having a brushed motor directly driven from AC
btw your last statement isn't true. brushless perform better. all modern electric vehicles use brushless motors

October 5th, 2020 08:10 AM #204Yeah I know. brushless are just magnetic levitation motors controlled by semicon to turn on a specific phase or duty cycle. Electric cars won't be efficient without using inverters. What I'm saying is with power tools, I have yet to see a demolition hammer drill using inverter. DC just whines at high RPM while brushed gets more torque. Its like comparing a honda engine to a diesel engine. Its not yet economically viable using inverter on corded power tools, aside from additional components, its not as reliable as brushed.

yeah coz demolition hammers won't benefit from inverter i.e. it's pointless
but i think you're confused about brushed motors having more torque. that's not true. brushless motors can be designed for low RPM torque (wound for more turns of thinner wire) or high RPM (thicker wires w/ less turns)

October 18th, 2020 06:28 PM #206Got a Deerma VC25 last 10.10 Shopee sale.
The low setting is good enough. 1 full charge would probably be enough for cleaning our small house.
Mga ilang gamitan kaya bago mawala yung "new appliance smell" from the motor?
Complaint ni misis mabigat daw. Sanayan lang siguro.
