Here, the article outlines the specific features that distinguish a brushless drill from a brushed.
This post also explains the merits and demerits of each type of drill motors so that you make an informed decision when purchasing a motor drill.
How a Power Drill Works
A power drill is an essential tool in the woodwork and construction projects.
Before dwelling on the details about brushed drill VS brushless, it is vital to understand how a motor drill operates.
The power drill is made to convert the electrical energy to mechanical energy.
The different specifications of electric motors, brushed or brushless, run on the same principle of electromagnetism.
As the motor windings receive power, a temporary magnetic field is created.
The effect that arises can then repel or attract the unit’s permanent magnets.
The magnets in electric motors facilitate the spinning motion of the motor shaft.
As the spinning continues, the current moves to different parts of the winding. The engine is powered, and the rotor turns continuously.
Operational Differences in a Brushless Drill VS Brushed
A brushed drill
The oldest drill in the power tool market is the brushed type invented in the 19th century. The motor drill has undergone various modifications to improve its operations.
A brushed drill derives its power from a brushed electric motor that has the following components; carbon brushes, commutator, magnets and the armature.
As the motor gets energized, charge moves from the battery through the carbon brushes into the commutator.
The armature and the commutator are attached to the motor shaft.
The armature, which consists of copper windings receives the charge from the commutator.
The armature and the commutator rotate on the motor shaft, which is within the motor.
The carbon brushes and magnets form the stationary components of the electric motor.
The carbon brushes are suspended by springs to enable them to make physical contact with the rotating commutator.
As current passes through the armature, electromagnetism occurs in the copper windings making the armature to spin.
A brushless drill
A brushless electric motor powers a brushless drill. The brushless electric motor is a recent technology invented in the 20th century.
However, its popularity has risen just recently due to its efficiency and durability.
The brushless technology in electric motors eliminates the need for commutator and carbon brushes.
The circuit board is the alternative component that replaces carbon brushes and commutator.
The other components of a brushless drill include the magnets and the armature.
The position of these two components is reversed compared to the location of the same parts in a brushed drill.
The magnets are positioned to the rotor while the armature is fixed and is stationary outside the motor.
A circuit board facilitates the energy delivery to the armature. A brushless drill also has a sensor that detects the rotor’s motion.
As circuit board regulates the power that travels to the armature, an electromagnetic field is created. The magnets position on the motor shaft starts spinning.
The original design of all brushless drills is similar.
However, small improvements can have significant on the performance of motor drill and its application.
For instance, motors that lack groove on steel rolling possesses low inductance which makes them perform faster with fewer ripples.
The other factor that affects the performance of a drill is a rotor pole number.
The higher the number of rotor poles, the less the speed and more torque.
Brushless motor is controlled by control algorithms which may be either trapezoidal, sinusoidal or vector commutation.
The control algorithm depends on factors such as the control software and the hardware.
The control software represents the program that is used to run the brushless drill motor.
There are merits and demerits associated with each type of control algorithm used.
