Anforderungen an die TherapeutInnen,In comparison to the steady-state operation of the DC-machine the energy storage elements (inductivities L., L. and inertia Θ) have to be considered additionally for the dynamic operation.

https://doi.org/10.1007/978-3-663-02556-6For the calculation of the dynamic operation of the induction machine the general set of equations for rotating field machines (space vector theory, please refer to Chap. 11) can be used. Because of the constant air-gap when neglecting the slotting effect any choice of α(t) is possible.

Rotating Field Theory,Induction machines and synchronous machines are rotating field machines. The stator construction of these machine types are principally the same, they differ in the rotor design. The similarity of these machine types are discussed first, later a detailed consideration of induction machine and synchronous machine will follow.
