Title: Motori tolerancija napona
Post by: Ikarus on April 22, 2016, 10:13:19 am
Zanima me dali je netko probao motore koji su po specifikacijama za 3s vozit na 4s. Imam na quadicu dys 1804 motore koji su već dosta izvozeni pa se razmišljam da ih probam na 4s . Sve ostale komponente mogu radit na 4s voltazi samo neznam šta bi bilo sa tim motorima. Ako je neko probao sličnu stvar molio bih da podjeli iskustvo.
Hvala 8)

Izgorit će sigurno. Bez obzira na opterečenje, manje propele i sl. Sve ovisi o namotima na statoru motora (prosjek, kvaliteta izolacije i broju namota) Najveći problem svega je pregrijavanje motora.

Probavao jesam, ali ovaj motor koji misliš stavit na 4S je jednostavno mali i pre slab (DYS 1804 2300KV) po eCalc u proračunu sa propelom 4x3 ide preko 130W a njemu je ograničenje 85W, na propele 4x2 (95W) a o potisku da negovorim.
