Do eddy currents in a rotor core of an induction motor create torque proportional to the coil current of a squirrel cage?
In a rotor of an induction motor, the core plates and wire coil conductors have non-zero thicknesses. Therefore, eddy currents non-zero too. And they approximately proportional to the coil current of ...

What's the difference between a direct drive/torque motor and a stepper?
A torque motor is 'either a rolled-up linear motor or a classic servo drive with a large number of poles'. As I understand it they are ironless 3 phase supply motors, though perhaps neither of these ...

How do I find the torque of a simple electrical motor?
I created a simple electric motor following Khan Academy's tutorial, and now I am trying to figure out how I can find the torque from it (which should be quite small).
Here is an image of the setup ...

How to find the back-EMF constant of BLDC motor from a motor technical data?
I have a BLDC motor with these info (please don't pay attention to the striped column):
How from these info, how can I get the Back-emf constant ? Is it just 36V/4krpm = 9 V/krpm ?
Thank you a lot.
