موتور براشلس KV930 A2212 مناسب برای کوادکوپتر و هواپیمای مدل موتور براشلس همانطور که از نامش پیداست فاقد جاروبک بوده و سیم پیچ آن دارای ساختار سه فاز 120 درجه ای می باشد در این موتور به دلیل حذف جاروبک اصطکاک ناشی از جاروبک حذف شده و بازدهی افزایش پیدا کرده است این کار سبب شده تا مدت زمان کار موتور با باتری در شرایط یکسان افزایش یابد و به دلیل داشتن دور بالا اکثرا در ربات پروازی کوادکوپتر مولتی روتورها و هگزا کوپترها به کار می رود موتور براشلس A2212  با توجه به نوع ساخت با تغییر دو فاز به صورت ساعتگرد و هم به صورت خلاف جهت ساعتگرد عمل می کند منظور از Clockwise و Counterclockwise در یک موتور براشلس جهت چرخش پیچ نگه دارنده ملخ ها می باشد که در این موتور به صورت ساعتگردClockwise است  کاربرد موتور براشلس A2212 ربات پروازی کوادکوپتر مولتی روتور    مشخصات موتور براشلس KV930 A2212 کیلوولت 930 حداکثربازدهی 80 درصد حداکثر بازدهی جریان 10  4 آمپر با بازدهی بیش از 75 درصد ظرفیت جریان 12 آمپر بر هر 60 ثانیه جریان در حالت بی باری در ولتاژ 10 ولت 05 آمپر تعداد سل های باتری برای راه اندازی موتور 2 الی 3 LiPoly ابعاد موتور 30  275 میلی متر قطر شفت 317 میلی متر   مستندات تست A2212KV930  Description A brushless DC electric motor BLDC motor or BL motor also known as electronically commutated motor ECM or EC motor and synchronous DC motors are synchronous motors powered by direct current DC electricity via an inverter or switching power supply which produces electricity in the form of alternating current AC to drive each phase of the motor via a closedloop controller The controller provides pulses of current to the motor windings that control the speed and torque of the motor Brushless DC motors typically have an efficiency of 8590 while brushed motors are usually only 7580 efficient Brushes eventually wear out sometimes causing dangerous sparking limiting the lifespan of a brushed motor Brushless DC Motors are quiet lighter and have a much longer lifespan Because computers control the electrical current brushless DC motors can achieve much more precise motion control Because of all these advantages brushless DC Motors are often used in modern devices where low noise and low heat are required especially in devices that run continuously This may include washing machines air conditioners and other consumer electronics They may even be the main power source for service robots which will require very careful control of force for safety reasons In a brushed DC motor the rotor spins 180degrees when an electric current is run to the armature To go any further the poles of the electromagnet must flip The brushes as the rotor spins make contact with the stator flipping the magnetic field and allowing the rotor to spin a full 360degrees A brushless DC motor is essentially flipped inside out eliminating the need for brushes to flip the electromagnetic field In brushless DC motors the permanent magnets are on the rotor and the electromagnets are on the stator A computer then charges the electromagnets in the stator to rotate the rotor a full 360degrees Brushless motors offer several advantages over brushed DC Motors including high torque to weight ratio more torque per watt increased efficiency increased reliability reduced noise longer lifetime no brush and commutator erosion elimination of ionizing sparks from the commutator an overall reduction of electromagnetic interference EMI With no windings on the rotor they are not subjected to centrifugal forces and because the windings are supported by the housing they can be cooled by conduction requiring no airflow inside the motor for cooling This in turn means that the motors internals can be entirely enclosed and protected from dirt or other foreign matter  Features KV 930 Max Efficiency 80 Max Efficiency Current 410A 75 Current Capacity 12A60s No Load Current  10V 05A No Of Cells 23 LiPoly Motor Dimensions 275 x 30mm Shaft Diameter 317mm
