Of course, keeping the size of the tool compact helps when working in tight spaces, and of course, running a super-efficient brushless motor results in very long runtimes from your battery.

The brushless motor ensures that the tool runs cooler, only draws the power it needs and gets you longer runtimes per charged battery.īrushless Impact Drivers – click to see what’s in stockįinally, a brushless impact driver is the sort of tool you’ll be reaching for all day long, ready for driving massive screws, fasting metal nuts or even making bit holes with spade bits.
Guaranteed longer runtime from fully charged batteries, better durability to handle vibration and lighter motors all add up to a superior performance from brushless SDS+ rotary hammer drills.īrushless Angle Grinders – click to see what’s in stockĪs with SDS+ rotary hammer drills, angle grinders require loads of efficient delivery and handling of power from the battery in order to work properly. Of course, a brushless motor will always provide the 3 great points mentioned above, but for these tools in particular, they are a game changer:īrushless SDS+ Rotary Hammer Drills – click to see what’s in stockīig-hitting tools that require plenty of power will always benefit from brushless motors. Board Pattern Drawing The circuit board example of the motor drive circuit in this guide consists of main board and interface board, taking into consideration the size reduction of the entire tool.
Watch our brushless motor video guide which explains the complete ins and outs of brushless motors:īelow we have listed some power tools which benefit from having a brushless motor. 18 Toshiba Electronic Devices & Storage Corporation 4. Some manufacturers claim that you’ll see around 30% longer runtimes from your batteries when they’re slotted into a brushless power tool. But add to this the fact that the motors are more durable, more able to withstand knocks and bumps, tend to be a little bit larger, and can more efficiently turn battery energy into power output, it becomes abundantly clear that brushless cordless power tools are just better than their brushed cousins. It goes without saying that motors with a smarter approach to drawing energy stored in the battery have a massive “tick” in their favour.

Overall, the motor is smarter, only using the energy required by the application, rather than just wanting to run on full power, which is typically the issue with older, brushed motors. They’re replaced by magnets and a small circuit board to coordinate the energy delivered by the battery to the windings of the motor. Rather than having, per a traditional brushed motor, carbon brushes, a ring of magnets, an armature, and a commutator, a brushless motor loses the brushes – obviously – and the commutator. There are 3 key points that make brushless power tools better than brushed:
