What is the difference between a brushless drill motor and a brushless drill motor?
The main difference between brushless or brushed drill motors is that the brushed variants are made of carbon while the brushless unit s use magnets to generate power. For this reason, brushless motors are better adapted, generate no friction, produce less heating and provide better performance.
What are the advantages of brushless motors?
The advantages of brushless technology are numerous. The absence of brushes eliminates problems associated with overheating and breakdowns. The service life of the brushless motor is therefore related only to the bearings. The brushless motor is more compact and two to three times lighter than brushed units.
Why are brushless motors better than stators?
The design of the brushless units reduces internal resistance and helps dissipate the heat generated in the stator coils. The efficiency is thus better since the heat of the coils can dissipate more efficiently thanks to the much larger stationary motor casing.
Why are carbon brushes used in motors?
They are installed on the fixed part of a motor to ensure optimal transmission of power to the rotor (the rotating part). They provide switching without the spark. Working in pairs, these components are wearing parts and subject to friction.
Why do motors have low heat dissipation?
They also have low heat dissipation capacity due to rotor limitations, high rotor inertia, low maximum speed, and electromagnetic interference (EMI) due to arcing on the brushes.
When did brushless motors become popular?
The brushless motor’s journey to prominence began in the early 1960s with the arrival of a power dimmer that had the capacity to convert alternating current (AC) to direct current (DC). In 1962, T. G. Wilson and P. H. Trickey published an article describing a brushless motor operating on direct current.
Why buy a corded electric drill?
Although cordless drills have made great advances, you're still reliant on a battery when you use one. A corded electric drill works anywhere there's a power socket – and it works all day and night if you need it to. Performance doesn't deteriorate as it does with cordless drills, and torque is usually higher, too.
Electric drill power
Corded electric drill power is measured in amps. An entry-level model for light-duty DIY tasks will be rated for around three amps. At the other end of the scale, general-purpose drills of professional-grade quality are rated at up to nine amps.
Electric drill speed
When evaluating the speed of an electric drill, consider that maximum speed is less important than variable speed. If you have a small drill bit and want to make a 1/16-inch hole in a piece of aluminum, you need high speed. However, if you're using a 1/2-inch spade bit in wood, you need slower speed.
Electric drill chucks
There are two types of chuck: keyed (also called Jacobs) and keyless. Keyed chucks have been around since the invention of the electric drill. The use of a key allows you to apply more force to tighten the drill bit.
Other electric drill features
Weight: General-purpose corded electric drills weigh anywhere from three to six pounds. That’s not particularly bulky, but it could be a consideration for users with reduced hand or arm strength. It's worth checking the weight of a drill before you buy because high performance doesn't always mean a heavier drill.
Electric drill prices
If you’re in the market for a low-cost electric drill, you can find a good one from a trusted brand like BLACK + DECKER for $30 or less. We advise potential buyers to stick with known brands with a proven track record for durability and reliability.
Safety tips
