Practical Implementation Of The Bridge Configured Winding For Self-Bearing Machines

Every electrical machine has a substantial magnetic flux. It transpires that if even a relatively small asymmetry of flux distribution exists in the air gap, a large unbalance magnetic force will pull the rotor towards the stator in the direction of the smallest airgap. Such a property is exploited in the so-called self-bearing machine where, as well as functioning as a motor or generator, the machine can also produce lateral forces.
