모터 동력계 벤치, 부하 뱅크, 전기구동 양산 검사에 관한 LANDI 엔지니어링팀의 선정 가이드와 시험 방법 노트.
Speed, torque, accuracy, cooling, software and acceptance criteria — the six specifications that decide whether a motor dynamometer bench will actually do the job, and what each one costs you if you get it wrong.
A purely resistive load only proves half of what a genset can do. This article explains the role of power factor, inductive and capacitive loading in real commissioning tests, and how to choose between containerised and rack-mounted load banks.
An e-drive assembly has to be performance-checked, NVH-judged and archived in about a minute. This article covers station layout, which tests to keep, and how pass/fail thresholds are set in practice.
A load bank is a controllable artificial load used to prove that gensets, UPS systems and power plants perform at real power. This article explains how one works, the resistive, inductive and capacitive types, and where each is used.
From rated capacity and power factor to voltage class, cooling and site conditions — the four calculations behind a load bank specification, and the mistakes that come up most often.
How eddy-current, AC and DC dynamometers differ in dynamic response, energy recovery and cost — and which test job each one suits.
Efficiency error is rarely set by the sensor datasheet. This article breaks down how torque, speed, electrical power and sampling synchronisation combine, and what actually reduces the error.
Why anti-islanding testing needs a precisely tuned RLC resonant load, what the quality factor Qf means, and where these tests most often go wrong.
Standby diesel sets running lightly for years accumulate unburnt fuel, carbon and lost power. This article covers the cause, how to recognise it, and how to run the periodic full-load exercise.
Alignment, coupling choice, range matching and calibration interval usually affect a torque measurement more than the transducer's accuracy class does.
