TorqueSlip Characteristics In Three Phase Induction Motor ...

The curve obtained by plotting torque against slip from s = 1 (at start) to s = 0 (at synchronous speed) is called torqueslip characteristics of the induction motor. It is very interesting to study the nature of torqueslip characteristics. We have seen that for a constant supply voltage, E 2 is also constant. So we can write torque equations as,

Fourbar linkage Wikipedia

A fourbar linkage, also called a fourbar, is the simplest movable closedchain linkage. It consists of four bodies, called bars or links, connected in a loop by four joints. Generally, the joints are configured so the links move in parallel planes, and the assembly is called a planar fourbar linkage. Spherical and spatial fourbar linkages also exist and are used in practice. Pumpjacks' main mechanism is a fourbar linkage
