Abstract :
Standstill forces on tubular induction machines are calculated by two methods: a simple one-dimensional technique and a two-dimensional axisymmetric finite element analysis. The end effect force produced by the finite length of the machine is calculated. The work is confirmed by tests taken on a practical machine
