What is brushless motor----working principle
What is brushless motor----working principle
A brushless DC electric motor (BLDC motor or BL motor) uses semiconductor switching devices to realize electronic commutator, that is, electronic switching devices instead of traditional contact commutator and brush.It has the advantages of high reliability, no commutating spark, low mechanical noise and so on. It is widely used in high grade recording seat, video recorder, electronic instrument and office automation equipment.

How to manage the quality for CNC machining parts?
The realization of customer requirements is finally achieved through internal transformation of requirements by the technology and quality department. Usually, customer requirements will be fully reflected through specific process and technical documents. Therefore, technical and quality department personnel are required to have high ability, which should be clearly defined in post responsibilities

Is the brushless motor alternating or direct current
The characteristics of brushless motors are that all motors with external characteristics of DC motors adopt electronic commutation are collectively referred to as brushless motors. Due to the appearance of brushless motor, the strict boundary between AC and DC speed regulation system has been broken.In the history of brushless motor, there have been two different brushless motor structures, namely brushless DC motor and alternating direction brushless motor.

What is CNC machining
CNC machining refers to the machining with CNC machining tools.CNC exponentially controlled machine tools are programmed by CNC machining language, usually G code.Nc machining G code language tells nc machine tool which cartesian position coordinates to use, and control the tool feed speed and spindle speed, as well as the tool converter, coolant and other functions.Numerical control machining has great advantages over manual machining. For example, the parts produced by numerical control machining are very accurate and repeatable.CNC machining can produce parts with complex shapes that cannot be processed manually. CNC machining technology is now widely promoted, most machining workshops have CNC machining capabilities, the most common CNC machining methods in the typical machining workshop are CNC milling, CNC turning and CNC EDM wire cutting (EDM wire cutting).

How to make a good CNC process plan for CNC machining parts
A good process plan for CNC machining parts needs to consider the following aspects:
Can meet the technical requirements of parts, can improve CNC processing efficiency, low processing cost, good quality control.
Therefore, the overall CNC process plan is usually as follows:
1. Selection of CNC machine tools.
2. Choose a solution.
3. Determine how to clamp the parts, then select clamp.
4. Positioning method.
5. Inspection requirements and methods.
6. Select the cutter.
7. Error control and tolerance control in machining.
8. Define CNC process.
9. CNC sequences.
10. Select cutting parameters.

Introduction about Brushed motor vs Brushless Motor (2)
Small Brushed DC Motor:
1. When the small brushed DC motor works, the winding coil and commutator rotate. The magnetic steel (i.e., the permanent magnet) and the carbon brush (i.e., the two contacts that provide direct current) do not rotate.The industry small brushed DC motor is divided into high speed small brushed DC motor and low speed small brushed DC motor. There are many differences between micro brushless DC motors and micro brushless DC motors. As you can see from the name, micro brushless DC motors have carbon brushes and micro brushless DC motors have no carbon brushes.
