Brushless DC electric motor
Synchronous electric motor powered by an electronic controller
A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows. The controller adjusts the phase and amplitude of the current pulses that control the speed and torque of the motor. It is an improvement on the mechanical commutator (brushes) used in many conventional electric motors.
The construction of a brushless motor system is typically similar to a permanent magnet synchronous motor (PMSM), but can also be a switched reluctance motor, or an induction (asynchronous) motor. They may also use neodymium magnets[1] and be outrunners (the stator is surrounded by the rotor), inrunners (the rotor is surrounded by the stator), or axial (the rotor and stator are flat and parallel).[2]
The advantages of a brushless motor over brushed motors are high power-to-weight ratio, high speed,

DC Motors: Fundamentals, Types, and Uses in Today&#;s Industry
In the bustling world of industrial machinery and advanced electronics, DC motors are unsung heroes, powering countless devices and systems around us. These motors have transformed industries with distinct designs and versatile applications, driving innovation everywhere. The journey of DC motors, from their inception to their pivotal role in contemporary applications, is fascinating.
As experts in manufacturing the DC motor cores that form the heart of these motors, we&#;re excited to delve deep into the intricacies of DC motors: their foundational principles, diverse types, and indispensable presence in today&#;s dynamic industry landscape.
History and Evolution of DC Motors
Journeying back to the late 19th century, the genesis of the DC motor marked a watershed moment in technological advancements. American inventor Thomas Davenport pioneered the first practical DC motor in But it wasn’t until the diligent efforts of scientists like Nikola Tesla and Thomas Edison that DC motors began to evolve and find a foothold in various industries.

Parts of a DC Motor
DC motors look something like this above, although there are ganska a few variations. These are used to omvandla electrical energy into mechanical energy and we can use these for example in our power tools, toy cars and cooling fans.
When we look at a DC motor, we first see the metall protective casing which forms the stator.
At one end we have the tip of a shaft protruding through the casing which we can attach gears, fan blades or pulleys onto.
On the other end we have a plastic end cap with two terminals. We can connect a power supply to these terminals to rotate the shaft.
If we remove the casing to look inside the motor, we then find two magnets which form eller gestalt the stator. These are permanent magnets which struktur a north and south m
