Components Compatible with QS Motor QS205 50H V3 3000W 3T (21")

QS205 50H V3-pattern direct-drive hub motor, 3000W rated, 3T winding, pre-laced into a 21" moped/motorcycle rim (150mm dropout). 205mm stator, 50mm magnet, 16 pole pairs, dual hall + KTY83 temp probe, disc brake. Sold by NBPower as 'NBpower/QS205 50H V3'; consistent with a genuine QS205 50H V3 (16pp aluminium) but not independently verified as QS-produced — NBPower units are stamped 'NBP WP50H'. Winding sets torque-per-amp and top speed (3T fastest ~1020rpm … 5T highest-torque ~650rpm); peak torque is a current-limited envelope, ~170-180 N·m at the 3kW/80A tier rising to ~200-220+ N·m at the 5kW/100A+ tier.
