Motor Noise
I think the rate of rotation is what's causing the weak air flow.
But this motor is fixed at 85 rpm, so I'll have to consider how to do this.
But that's the top speed for ones I can get cheap on Amazon...
There!

It's making a heck of a racket, isn't it?

  • がんばれ小傘さん 3211

    だんだんと流れが怪しくなってきましたよ?(笑)

    モーターがこの比率で回転させられるギリギリのトルクだったようです。
    モノタロウあたりで探せばもっと速いACモーターを売ってるんですけど、6000円~1万円近くするのでさすがに買えません。
    DCモーターだと追加で電源回路を用意しないといけないのでこんなかんじに。

    プーリーもちょうどいいものがなかったのでMDF板を切って自作しました。
    伝動ベルトは溶着するタイプのゴム紐を切って作りました。

    このあたりから、作るのが楽しくなってきて静音性は二の次になってきました。
    本末転倒ですね!(笑)

    Hang in There, Kogasa-san 3211

    The flow's gradually become more and more suspicious, right? :-)

    It seems the motor just barely had the torque to be made to run at this ratio. If you search places like MonotaRO, they sell faster AC motors, but they go for ¥6K to nearly ¥10K, so naturally, I couldn't buy one. I'd have to prep an additional power supply if I went with a DC motor, so here we are.

    I didn't have exactly what I needed for a pulley, either, so I cut up some MDF panels and made one myself. I cut up a welding-type elastic band to make the drive belt.

    From around this point on, making stuff became more fun, so quietness became a secondary concern. Got them priorities backwards! :-)
