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 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

I have come across a dual coil ignition system as used by Jaguar on their V12 in the 1980's. It uses two ignition coils with their primary windings wired in parallel. The primary coil has its secondary winding wired to the distributor and then to the spark plugs as is standard practice. However, the auxiliary coil has it secondary winding output sealed off. The purpose of the system was to provide a stronger spark to the plugs, always a difficult task with the very short dwell time of a...
