Nettet14. okt. 2024 · 사실 이 Insulation Class는 모터 내부에 감겨져 있는 Winding 즉, Wire의 절연등급을 의미하는 것이지만 Wire 자체의 등급이라기 보다 Wire에 코팅 혹은 Varnishing(광택)된 재료에 의한 Insuation 등급이라고 보면 된다. 보통 Insulation Class는 Winding Insulation Class라고 부르기도 한다. The electrical insulation system for wires used in generators, electric motors, transformers, and other wire-wound electrical components is divided into different classes by temperature and temperature rise. The electrical insulation system is sometimes referred to as insulation class or thermal classification. … Se mer The maximum hot-spot operating temperature is reached by adding the rated ambient temperature of the machine (often 40 °C), a temperature rise, and a 10 °C hot-spot allowance. Electrical machines are usually designed … Se mer • Insulator (electricity) • Electrical insulation paper Se mer In IEC standards, the insulation system is a classification based on the level of electrical shock protection given to a user.

Nettet6. jan. 2010 · Insulation "Class" has to do with temperature rise, not voltage spikes. VFD controlled motors should have higher VOLTAGE ratings on the winding insulation, but that is NOT reflected in the class rating. Class F is a really good idea, but not an absolute. If for instance your pumps are in a well ventilated space, Class B would probably be fine. NettetThere are basically four classes of insulation - A, B, F and H - class F being the most commonly used. These insulation classes were established to meet motor …
