H02P2203/00 - CPC Classification

Classification description:

Indexing scheme relating to controlling arrangements characterised by the means for detecting the position of the rotor

Sub-classes:

H02P2203/01 » Motor rotor position determination based on the detected or calculated phase inductance, e.g. for a Switched Reluctance Motor 46
H02P2203/03 » Determination of the rotor position, e.g. initial rotor position, during standstill or low speed operation 105
H02P2203/05 » Determination of the rotor position by using two different methods and/or motor models 54
H02P2203/07 » Motor variable determination based on the ON-resistance of a power switch, i.e. the voltage across the switch is measured during the ON state of the switch and used to determine the current in the motor and to calculate the speed 5
H02P2203/09 » Motor speed determination based on the current and/or voltage without using a tachogenerator or a physical encoder 51
H02P2203/11 » Determination or estimation of the rotor position or other motor parameters based on the analysis of high frequency signals 80
