This topic shows how to drive a BLDC motor using Arduino where the speed is controlled with a potentiometer. The brushless dc (BLDC) motor is a 3-phase motor comes in two main types: sensored and sensorless. The sensorless BLDC motor control technique is based on the BEMF (Back Electromotive Force) produced in the stator windings.
Most BLDC Motors use three Hall Sensors that are embedded into the stator to sense the rotor's position. The output of the Hall Sensor will be either HIGH or LOW depending on whether the North or South pole of the rotor passes near it. By combining the results from the three sensors, the exact sequence of energizing can be determined.

Key learnings: BLDC Motor Definition: A brushless DC motor is defined as an electronically commutated motor that lacks brushes, enhancing operational efficiency and torque.; Core Components: The two primary components of a BLDC motor are the rotor, which rotates, and the stator, which remains stationary.; Operational Efficiency: BLDC motors excel in …
Le moteur semble surdimensionné (par exemple, dans les combinaisons réducteur-moteur, la vitesse du moteur est limitée par la vitesse d'entrée maximale du réducteur). Fonctionnement à court terme. La puissance de sortie des moteurs CC et CE (BLDC) en fonction du couple présente une dépendance parabolique (voir diagramme).
The BLDC motor (sensored or sensorless) is a 3 phase DC motor which means it has 3 winding on the stator core. Two coils are energized at a time to create a rotating electric field. This method is fairly easy to implement, but to prevent the permanent magnet rotor from getting locked with the stator, the excitation on the stator must be ...

This tutorial will cover how to interface the BLDC motor with STM32 using the PWM. The basic requirement for this tutorial to work is that you must have a BLDC motor connected to the controller via an Electronic Speed Controller (ESC). I have a 1400KV BLDC motor and a 30A ESC. Their pictures are shown below.

As with all BLDC motors, this one is driven by a three-phase half-bridge of transistors (See 2nd photo below). I used an IC made by ST Microelectronics (L6234) for the bridge, also known as the motor driver. The electrical connections for the L6234 are shown in Step 8.

BLDC motors are synchronous, with the magnetic fields generated by the rotor and stator both rotating at the same frequency. This helps prevent slippage observed in many high induction motors. Although single-phase, two-phase, and three-phase motors are available, three-phase designs are by far the most popular in today's applications. ...
