Etymology

"The name is derived from the similarity between this rings-and-bars winding and a hamster wheel (presumably similar wheels exist for pet squirrels)." Is this based on anything? I'm pretty certain it's essentially right but that the term comes by way of French Cage à écureuils which I believe is much older and goes back to the days before electronics (a treadmill if I'm not mistaken). - Jmabel | Talk 20:20, 8 August 2008 (UTC)[reply]

wikt:fr:cage à écureuil gives it in the sense of a similarly shaped playground fixture. - Jmabel | Talk 20:23, 8 August 2008 (UTC)[reply]

Slightly slower speed?

Not an expert... but shouldn't it refer to a lagged phase rather than slower speed that induces torque? 82.69.54.182 (talk) 15:29, 21 September 2008 (UTC)[reply]

Think of any squirrel-cage motor as also being a generator that generates a counter-voltage that must be deducted from the line voltage to arrive at the current and torque produced. If the load is higher, then the speed is lower to produce lower counter-voltage, and therefore also higher current and higher torque. 70.27.152.243 (talk) 20:37, 20 July 2016 (UTC)[reply]

History

Invented by whom, when ? Will also shed some light on the etymology ... --195.137.93.171 (talk) 08:34, 6 April 2013 (UTC)[reply]

Inconsistency

The text states that the stator has more windings than the rotor, yet the laminate picture clearly shows the rotor (inner circle) having more windings than the stator (outer circle) - unless this laminate is from a motor where the outside rotates (i.e. is the rotor)? — Preceding unsigned comment added by 5.148.6.34 (talk) 13:34, 26 August 2015 (UTC)[reply]
