33mm Long Life 12V Small Size DC Brushless Motor

The VBL-3338 is a high-performance brushless motor developed by the Weishida, with excellent torque and high-speed rotation capability. The motor uses advanced brushless technology to achieve high efficiency and durability, so it is widely used in aircraft, vehicles, drones, ships and other applications. Low noise, low energy consumption, etc., can meet the user's needs for high processing capacity and long time work. In addition, it has a variety of protection mechanisms, which can avoid damage during use, and maintain a reliable and stable working state.33mm Long Life 12V Small Size DC Brushless Motor consists of two parts: rotor and fixator. There is a permanent magnet on the rotor and three stators on the fixator, each wound with a set of windings. When the driving power supply is applied to the stator winding, the magnetic field generated by the winding is also different due to the different current in the winding, which interacts with the permanent magnet on the rotor, thus rotating the rotor.

The brushless DC motor is mainly composed of a rotor made of a permanent magnet material, a stator with a coil winding, and a position sensor. The stator consists of stacked steel stacks with axial grooves for winding. The windings in BLDC are slightly different from those of conventional induction motors. The rotor part consists of permanent magnets (usually rare earth alloy magnets such as neodymium, samarium cobalt and NdFeB. Depending on the application, the pole number can vary between two and eight, with the Arctic and Antarctic placed alternately. The position sensor (Hall sensor) is not brush in the brushless motor, so the change is electronically controlled. In order to rotate the motor, the stator windings must be energized sequentially, and the location of the rotor (i. e., the North and South poles of the rotor) must be known to accurately energize a specific set of stator windings.The position sensor of the Hall sensor (working based on the Hall effect principle) is usually used to detect the position of the rotor and convert it into electrical signals. Most BLDC motors use three Hall sensors that are embedded in the stator to detect the position of the rotor. Whether the output of the Hall sensor will be high or low, depending on whether the rotor is Antarctic or nearby. By combining the results of the three sensors, the exact order of electrification can be determined.

The basic rule is the left-hand rule is used to determine the direction of the force of an electrical conductor in a magnetic field. F = BILsinθ, where B is the magnetic induction intensity (unit T), I is the current (unit A), L is the effective length of the conductor (unit m), F is the force (unit N), and θ is the Angle between B and I.

Brushless DC motor does not use a brush. The brushless DC motor does not use a commutator to regulate the current inside the coil, but uses an electronic commutator to transmit a current that generates an AC electrical signal that leads to motor drive. The Lorentz force law states that the carrier conductor is force as long as it is placed in a magnetic field.Due to the reaction force, the magnet will bear equal and opposing forces. When the coil through the current, will produce a magnetic field, the magnetic field is driven by the stator pole, with polarity, heterpolarity attract each other, if continuously change the direction of the current in the coil, the rotor induced the magnetic field will continue to change, so the rotor will rotate under the action of the magnetic field. The carrier conductor (stator) is fixed, while the permanent magnet (rotor) is moving. When the stator coil gets power from the power supply, it becomes an electromagnet and starts producing a uniform magnetic field in the air gap. Although the power supply is DC, the switch still generates an AC voltage waveform with a trapezoidal shape. The rotor continues rotating due to the interaction force between the electromagnetic stator and the permanent magnet rotor. By switching the windings to high and low signals, the corresponding windings are motivated for the Arctic and Antarctic. The permanent magnet rotor with the South and North Pole aligned with the stator pole, causing the motor to rotate.

The drive mode of brushless straight electromechanical can be divided into various modes according to different categories, and each has its own characteristics.
According to the drive waveform: square wave drive, this drive mode is convenient to achieve, easy to realize the motor without position sensor control;
Sinusoidal drive: This drive mode can improve the operation effect of the motor and make the output torque uniform, but the implementation process is relatively complex. At the same time, this method has SPWM and SVPWM (space vector PWM), the effect of SVPWM is better than SPWM.
