In this video number {842} BLDC motor teardown. I explained how to dismantle / teardown / disassemble brushless dc motor, it is used in LG ac indoor unit EAU62543503, EAU62543502, 4681A20091W. Brushless DC electric motor (BLDC), known as an electronically commutated motor, is a synchronous motor using a direct current (DC) power supply. It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows. The controller adjusts the phase and amplitude of the current pulses that control the speed and torque of the motor. The construction of a brushless motor system is typically similar to a permanent magnet synchronous motor (PMSM), but can also be a switched reluctance motor, or an induction (asynchronous) motor. They may also use neodymium magnets and be out-runners (the stator is surrounded by the rotor), in-runners (the rotor is surrounded by the stator), or axial (the rotor and stator are flat and parallel). The advantages of a brushless motor over brushed motors are high power-to-weight ratio, high speed, nearly instantaneous control of speed (rpm) and torque, high efficiency, and low maintenance. Brushless motors find applications in such places as computer peripherals (disk drives, printers), hand-held power tools, and vehicles ranging from model aircraft to automobiles. In modern washing machines, brushless DC motors have allowed replacement of rubber belts and gearboxes by a direct-drive design • You are Invited to Join Haseeb Electronics • / @haseebelectronics • Please check other videos • SMPS no output • {966} SMPS Is not working, not turnin... • SMPS step by step repair tutorial • {528} How To Repair SMPS || SMPS Repa... • How to download circuit diagram, service manual • {558} How To Download Circuit Diagram... • Transistor, IGBT, MOSFET equivalent • {233} How to find Equivalent or Subst... • Broken plastic gear repair • {679} How To Repair Broken Plastic Ge... • You can Follow me on :- • Instagram: / haseebelect • Facebook: https://web.facebook.com/profile.php?... • #bldcmotor #disassembly #electronics
