High power Brushless dc motor

The VBL-4321 is a high-performance external rotor brushless motor developed by Weishida, with a number of excellent features and performance. The motor uses cutting-edge digital control technology, which offers the benefits of long life, excellent stability, and great reliability. Its highly integrated features, which include built-in temperature protection, speed feedback, and motor control, not only lower the motor's volume but also significantly increase the system's stability and safety. The motor has an effective sliding tile bearing design that may lower friction during mechanical rotation and guarantee the system's stability and longevity throughout time. High power Brushless dc motor The rotor is located outside the motor, while the stator is inside. This structure has higher speed, greater torque and better thermal stability compared to traditional brushless motors. It consists of motor shaft, rotor, stator and electronic controller.

The rotor and stator make up the two main components of the brushless outer rotor motor. A collection of powerfully magnetic permanent magnets affixed to the exterior cylindrical rotor make up the rotor. One thousand coils, fixed to the inner cylindrical stator, make up the stator. The rotor may rotate inside the stator because of a specific space that exists between them. The creation of torque between the current and the magnetic field's rotation is the basic idea at work. A magnetic field that interacts with the permanent magnet on the rotor is created when current flows through the stator coil. Outer rotor power brushless motors use a design with an external rotor that provides smooth, stable rotation. These motors are capable of achieving higher torque than comparable sized inner rotor designs. The higher inertia produced by external rotor motors makes them ideal for applications that require lower noise and reliable performance at lower speeds.

It is made of high strength materials and is equipped with the latest magnet technology, giving it high efficiency and low noise when operation. The rotor rotates through a magnetic field without the need to touch the stator, so it is also known as a "contactless motor". Can transmit power more efficiently and withstand higher loads. 

A Hall encoder is a sensor that uses magnetoelectric conversion to change the mechanical geometric displacement on the output axis into a pulse or a digital number. It is made up of the Hall element and the Hall code disk, or magnetic ring. The Hall code disk is evenly distributed around a circular plate with distinct magnetic poles that has a given diameter.

Product Description

Unlike brushed motors, brushless motors allow you to flexibly set the input power (voltage, current) waveform of the stator coil when you know the rotor position, or the position connection between the permanent magnet and the stator coil. In other words, the rotor and excitation coil positions need to coincide. The ideal timing to feed the power waveform to the motor coil is when the two positions coincide. There is a chance that the motor's actual steering will be entirely different from what was anticipated if the positions do not match at different beginning points. As a result, it is crucial to detect the rotor position.

The sensor is used to detect the rotor position, and the detection methods are also varied
Direct detection of the rotor position by using a Hall element (also known as a Hall sensor)
Using an encoder (photoelectric type, decomposition type) method
Position estimation method of detecting electric current
Position estimation method of detecting the reverse electromotive force generated during motor rotation

1. The motor of the outer rotor revolves externally. Typically, the coil part is non-spinning while the imbedded magnetic steel part is rotating.
2. Heat dissipation is better, maintenance is easy, but the internal rotor motor requires tough maintenance and it is difficult to circle the internal coil.
3. While the outer rotor motor is precisely the opposite, the rotational inertia is greater than that of the inner rotor.
4. Typically utilized for impellers, providing effective cooling.
5. The inner rotor motor's torque is marginally softer and smaller, while the external torque is stronger and harder.

FAQ

Is the position sensor important in the motor matter?

The torque in the motor is produced by the current passing through the armature as a result of the rotor's magnetic flux crossing the chain armature. Therefore, interference with the magnetic flux Φ a must be avoided as much as possible when the magnetic flux Φ an is generated by the electric current flowing through the armature. This will allow the position sensor to precisely detect the magnetic flux Φ g of the rotor in the rotation. Thus, the most important thing to consider while designing the brushless motor position sensor's layout is how to reduce the position sensor's detection error.
