Hey i'm DIVYA SHREE NANDINI. I'm here to present my topic on INDUCTION MOTOR. An INDUCTION MOTOR is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction. Wanna know more about it then check it out. If you've any queries about it then you can ask me. Thank You! :)

Putting the SPARK into Virtual Training.pptxCynthia Clay
ย
This 60-minute webinar, sponsored by Adobe, was delivered for the Training Mag Network. It explored the five elements of SPARK: Storytelling, Purpose, Action, Relationships, and Kudos. Knowing how to tell a well-structured story is key to building long-term memory. Stating a clear purpose that doesn't take away from the discovery learning process is critical. Ensuring that people move from theory to practical application is imperative. Creating strong social learning is the key to commitment and engagement. Validating and affirming participants' comments is the way to create a positive learning environment.

RMD24 | Debunking the non-endemic revenue myth Marvin Vacquier Droop | First ...BBPMedia1
ย
Marvin neemt je in deze presentatie mee in de voordelen van non-endemic advertising op retail media netwerken. Hij brengt ook de uitdagingen in beeld die de markt op dit moment heeft op het gebied van retail media voor niet-leveranciers.
Retail media wordt gezien als het nieuwe advertising-medium en ook mediabureaus richten massaal retail media-afdelingen op. Merken die niet in de betreffende winkel liggen staan ook nog niet in de rij om op de retail media netwerken te adverteren. Marvin belicht de uitdagingen die er zijn om echt aansluiting te vinden op die markt van non-endemic advertising.

5. Similarly if various instances are considered upto 360
o
, it is seen
that the resultant always has a magnitude of 1.5 times peak
value and pointing in a direction at the angle of
consideration.
For every 360
o
, the resultant magnetic field completes one
rotation.
Inference:
When 3 phase currents flow in a balanced 3 phase winding, a
rotating magnetic field is created which has constant
magnitude, but rotates in synchronism with supply
frequency.
This speed of rotating magnetic field is called SYNCHRONOUS SPEED
