H02K23/02 - CPC Classification

Classification description:

DC commutator motors or generators having mechanical commutator; Universal AC/DC commutator motors characterised by arrangement for exciting

Sub-classes:

H02K23/023 » {having short-circuited brushes} 5
H02K23/026 » {having an unregular distribution of the exciting winding or of the excitation over the poles} 2
H02K23/04 » having permanent magnet excitation 168
H02K23/06 » having shunt connection of excitation windings 5
H02K23/08 » having series connection of excitation windings 12
H02K23/10 » having compound connection of excitation windings 2
H02K23/12 » having excitation produced by a current source independent of the armature circuit 1
H02K23/14 » having high-speed excitation or de-excitation, e.g. by neutralising the remanent excitation field 0
H02K23/16 » having angularly adjustable excitation field, e.g. by pole reversing, by pole switching 3
H02K23/18 » having displaceable main or auxiliary brushes 24
H02K23/20 » having additional brushes spaced intermediately of the main brushes on the commutator, e.g. cross-field machine, metadyne, amplidyne, other armature-reaction excited machine 17
H02K23/22 » having compensating or damping winding 6
H02K23/24 » having commutating-pole winding 4
