BLDC HDD MOTOR AS GENERATOR Frequency Out 600Hz 11.5VAC
« Reply #1 on: September 09, 2022, 01:54:37 PM »
SHORT VIDEO
Just test Freq and Voltage out from BLDC HDD as generator 3 Phase  test for 1 Phase only
Dont Forget to Subscribe to My Youtube Chanel Video for my other project
Remember : More High speed = more high Frequency = more High Ampere out (Because more low Inductive Reactance) <<< This is the reasson Why more Faster generator spinning then The Current (Amp) Produced more high

How much polus of magnet your rotor has?
It is important for ratio rpm and frequency,I suppose.
p.s. Could I come to your Indonesia, like forever?   ;)

regarding the number of magnetic poles of the BLDC HDD rotor, sorry I really don't know but for other BLDCs that have the same three-phase from used part ofphotocopy machine components as in the picture it has 16 magnetic poles. regarding the high frequency produced by the bldc hdd as a generator, return to the physics formula F=Number of pole X Speed ​​(Rpm) / 120 so the way I get high frequency is using speed and it can be seen in the pulley ratio in the motor driver 5x or more than the pulley in the bldc hdd generator. please watch the video again. this can happen because BLDC HDD has almost no cogging / very very low cogging. so it is very easy to get high speed just play pulley ratio and speed of dc motor Driver, on my test with 7VDC I get 300Hz on it

Please look at pulley ratio, on the left is dc motor (4000Rpm on 24VDC) as Driver and the right is BLDC HDD motor as generator

Continued testing of bldc hard drive motors. This time, the three phase AC outputs are fullbridge rectified and the capacitors become one DC output

As a Driver use 24VDC Motor
36VAC 800Hz output Gnerator from 1 phase test
