VFD / Variable Frequency Drive මගින් මෝටර් වේග පාලනය කරමු / Engineering Technology A/L

How #variable_frequency_drive controls speed of #3_phase_induction_motor. #VFD_motor_control for AC induction motors, have been the innovation that has brought the use of AC motors back into prominence, with ease of motor speed controlling. By using the #VFD, induction motor can get its speed controlled, by changing the #frequency of the supply voltage. At first, #Variable_speed_drive converts fixed AC voltage into DC voltage through a bridge rectifier. Then, DC voltage is filtered and smoothened through capacitors and inductors in the #DC_bus, before transforming it back in to the AC voltage through the inverter. Resultant AC voltage frequency is not fixed, and is maneuverable to get required magnitude for motor speed controlling. Operation of VFD is explained here in this video well with fine animation work. වේරියබල් ෆ්රික්වන්සි ඩ්‍රයිව් නැත්නම් VFD එකෙන්, 3 phase මෝටර් ස්පීඩ් කොන්ට්‍රෝල් කරන්නේ කොහොමද කියලා මේ වීඩියෝ එකෙන් බලන්න.
