AI Thread Summary
Armature and copper windings are crucial components in electric motors, particularly in shaded pole motors. The armature, often featuring an offset design, enhances rotational movement by optimizing airflow and torque generation. Copper windings create a magnetic field that interacts with the armature, facilitating rotation. The closed-loop copper wires not only help maintain structural integrity but also contribute to the motor's electrical dynamics by providing a phase shift essential for torque production. Understanding these elements is key to grasping motor functionality.

What are these ?? in a motor?

I've taken a squirle cage ventilation motor appart to see what the laminations of the core material is within the electric coil. The core material then capsules an armature with an angled/off-set, made of aluminum vanes. How does the off-set aid in the armature rotating? What I also noticed is that there are two closed-loop, bare copper wires encircling the metal laminations, as if it were holding the whole essemble together. What is the electrical dynamic involvement with theses copper wires or is it simply for essembling porposes?

Thanks

It sounds like you are describing a shaded pole motor. The copper loops provide a phase shift for torque purposes.
 

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 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
