What sort of motor is used in the lead retraction device in my vacuum cleaner?

AI Thread Summary
The Vampyr 731i vacuum cleaner features a lead retraction device that may utilize a spring mechanism, as the retraction occurs when the power cable is unplugged. There is uncertainty about whether a motor is involved, with suggestions that a spring could be responsible for winding the cable back in. The discussion raises the possibility of a battery being present due to the vacuum's quarter turn rotary switch. However, specific technical details about the motor or mechanism are not readily available online. The inquiry highlights a lack of accessible information regarding the device's inner workings.

I can't find the technical information online
Howstuffworks.com only gives the information that the fan motor is electrical

Could it just be spring loaded?
You wind up a spring by pulling the power cable out and then release it and it winds back in.

Wouldn't it have to be a spring? It happens when the power cable is unplugged. So how would you power a motor?
 
It must have a battery in it because it has a quarter turn rotary on switch.
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Two capacitors, etc.'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
