Does a Needle Possioner make Noice at Low Speed?

by

Yes, a needle positioner can make noise at low speed. Needle positioners are small devices attached to sewing machine motors that control the stopping position of the needle, either up or down, to improve precision during sewing.

Here are some reasons why a needle positioner might make noise at low speeds:

1. Motor Adjustments

  • At low speeds, the motor connected to the needle positioner may create a clicking or humming noise as it adjusts to maintain the correct needle position.
  • This noise is more noticeable when the motor has to engage intermittently or apply a little extra torque to control the needle position precisely.

2. Electrical Adjustments and Friction

  • Inside the positioner, there are electrical adjustments that happen to monitor and keep the needle in place, which can produce a slight buzzing or whirring noise.
  • Friction between the internal parts of the positioner and the needle bar or shaft can also create subtle noises.

3. Old or Worn Needle Positioner

  • Over time, needle positioners can develop wear and tear, especially if they’re older models or have been heavily used. Worn parts or loose components inside the positioner might cause it to rattle or buzz.
  • Regular maintenance, including lubrication, can sometimes reduce this noise.

4. Brand and Model Differences

  • Some models are inherently quieter than others, as they’re designed with sound-dampening features. If your machine has an older or simpler model of positioner, it might lack these quieter components.

How to Minimize Noise

If the noise is bothersome, here are a few tips:

  • Lubricate the machine and positioner as specified in the user manual, especially if it’s been a while.
  • Check for Loose Parts: Ensure all screws and fittings on the positioner are tightened.
  • Upgrade the Positioner: If noise is a persistent issue, consider upgrading to a quieter or more advanced needle positioner if your machine allows it.

In general, while some noise is normal at low speeds, excessive rattling or grinding noises may indicate wear or a need for adjustment.
