Ping360 sonar head oil filled, if there is a flow noise when motor spin?
The rotations are not fast enough to cause any kind of flow noise, especially without air in the transducer head. The motor is a stepper motor though, so if you’re trying to tell if it’s moving you should be able to feel small vibrations as the motor steps through each position, with a fingertip placed on the outside of the device.
Okay, thank you very much for your reply. Finally, would you like to ask if it is convenient to provide purchasing channels for stepper motors? I want to buy it for testing.
We don’t sell stepper motors, so you’ll need to find some other supplier for those I’m afraid.
