Definitions for "Commutation"
A term that refers to the action of steering currents or voltage to the proper motor phases so as to produce optimum motor torque. In brush type motors, commutation is done electromechanically via the brushes and commutator. In brushless motors, commutation is done by the switching electronics using rotor position information typically obtained by hall sensors, a tachsyn, a resolve, or an encoder.
controlling the currents or voltages in the motor phases in an effort to optimize motor performance; can be achieved mechanically or electrically.
1. A term which refers to the action of steering currents or voltages to the proper motor phases so as to produce optimum motor torque. In brush type motors, commutation is done electromechanically via the brushes and commutator. In brushless motors, commutation is done by the switching electronics using rotor position information obtained by Hall sensors, a Tachsyn, or a resolver. 2. Commutation of step motors is normally done open loop. Feedback from the motor is not required to hold rotor position precisely.
The change of a penalty or punishment by the pardoning power of the State; as, the commutation of a sentence of death to banishment or imprisonment.
The reduction of a sentence, as from death to life imprisonment.
The reduction of a sentence. In January 2003, Governor Ryan commuted all 167 Death Row inmates' death sentences to sentences of life without parole.
A substitution, as of a less thing for a greater, esp. a substitution of one form of payment for another, or one payment for many, or a specific sum of money for conditional payments or allowances; as, commutation of tithes; commutation of fares; commutation of copyright; commutation of rations.
The option of exchanging pension for cash at retirement at a fixed rate.
This term refers to withdrawing a lump sum from a pension/annuity.
The termination of all obligations between the parties to a reinsurance agreement, accompanied by a final cash settlement. Commutation may be required by the reinsurance agreement or may be effected by mutual agreement.
In the event of the termination of this contract, the Reinsurer shall be released from all further liability to the company for all loss and allocated loss expense not finally settled by the company as of the date of termination. In consideration of that release, the Reinsurer shall pay to the Company all amounts of loss and allocated loss expense due for losses finally settled.
Transaction in which policyholders or insurers surrender all rights and are relieved from all obligations under an insurance or reinsurance contract in exchange for a single current payment. Insurance Provides monetary help in times of trouble and difficulties usually when an insured individual dies or is dismembered.
