Translation guide
A commutator is a specialized technical term with two main meanings: an electrical component in motors/generators and a mathematical concept in algebra. This guide focuses on the electrical meaning, which is more common for learners, and briefly covers the mathematical usage.
A rotary switch in electric motors and generators that reverses current direction.
Standard technical term for the commutator in motors and generators. Used in engineering and technical contexts.
An element measuring non-commutativity in a group or ring.
The English word 'commutator' maps to different Japanese terms depending on the field. Using 整流子 in a math context or 交換子 in an electrical context will cause confusion. Always check the domain before translating.
The motor's commutator is worn out.
Katakana loanword from English, commonly used in technical manuals and by engineers. Slightly less formal than 整流子 but widely understood.
The commutator needs to be replaced.
Mathematical term for commutator in group theory and ring theory. Used in abstract algebra contexts.
Calculate the commutator subgroup of the group.
Katakana loanword also used in mathematical contexts, especially in physics-related algebra. Less common than 交換子 in pure math.
In quantum mechanics, the commutator of operators is important.
