Rotary electrical machine with commutator and series windings - has cyclic distribution of conductors in rotor slots with coil sections in pairs on either side

摘要

The rotating electrical machine has a commutator and the windings are connected in series. The mechanical commutator consists of N-laminas which are cyclically connected to a branch between two sequential series connected windings. The motor is esp. for use in domestic appliances such as mixers. Each coil is distributed on both sides through at least two slots (1, 6) on the rotor. This distribution is applied in a cyclically permutating manner for all the coils around the circumference of the rotor. this means that each slots contain parts of sides of coils of at least two sequential coils on one side and two of another two coils on the other side.
