I'm studying induction motors and there's a few things I'm not following.

Firstly, on a torque-speed curve I'm assuming the speed refers to rotor speed as a percentage of the synchronous speed.

What is full load? if a motor can produce enough torque to move a load then full load I can only assume to be when the motor is producing maximum torque i.e. operating at it's maximum power. For a NEMA type B motor for example this is about 200% of 'full load' therefore my assumption does not hold true.

Also, the full load torque is by definition the torque produced at rated power. What is rated power? - Obviously I understand it is the power rating on the nameplate but what does it actually mean?

Have you looked on the Internet and typed in "all about circuits", this is a great resource for all types of electrical knowledge

Hope this helps
