Washing machine drain pump motor type

AI Thread Summary
The discussion centers on the type of motor used in a washing machine drain pump, specifically questioning the absence of brushes. It is suggested that the motor is likely an induction type, possibly a Shaded Pole motor, known for being inexpensive and low-maintenance. The efficiency of these motors is noted to be low, but they are reliable for the short operational lifespan of washing machines. A resource link is provided for further understanding of AC motors. Overall, the conversation highlights the practicality of using induction motors in this application.

Brush motors are a lot of hassle for that sort of application. It will almost certainly be an induction motor and the ones I've seen looked like Shaded Pole types. Not very efficient but trouble free and cheap and they don't run for long over the life of the machine.
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Electromagnet magnetic field issue'

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
