S series motors

The Danfoss Char-Lynn S series motors with optimized Geroler sets and steel end caps offer enhanced performance with reduced drive-running angle while retaining a compact package size. The Geroler set has precision-machined rollers in the outer ring to support the rolling contact between the star and ring. This improves mechanical efficiency, especially at start-up and at low speeds. These motors provide reliable, leak-free performance and smooth start-up operation.
