by reversal of phase sequence of connections to the motor

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Arrangements for stopping or slowing electric motors, generators, or dynamo-electric converters > for stopping or slowing an individual dynamo-electric motor or dynamo-electric converter > for stopping or slowing an AC motor > by reversal of phase sequence of connections to the motor

CPC:

Arrangements for stopping or slowing electric motors, generators, or dynamo-electric converters (stopping of synchronous motors with electronic commutators H02P6/24; stopping dynamo-electric motors rotating step by step H02P8/24; vector control H02P21/00) > for stopping or slowing an individual dynamo-electric motor or dynamo-electric converter > for stopping or slowing an AC motor > by reversal of phase sequence of connections to the motor

No child classifications to compare. This is a leaf node in both IPC and CPC.
