gravitational force - (physics) the force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface; "the more remote the body the less the gravity"; "the gravitation between two bodies is proportional to the product of their...
To find the force of attraction between the pole faces, the standard virtual work approach is used: (4.3.4)Fx=−∂Wmag∂g=−B22μ0hl. In the case of an electric machine with smooth stator and rotor surfaces, the flux density normal to the ficititious “pole faces” is the radi...
