Описание:
The EMS1-20L25 is the largest frame size of the Bosch Rexroth eLION EMS1 series, designed for high‑power off‑highway applications requiring extreme robustness. It is a liquid‑cooled permanent‑magnet synchronous reluctance motor (PMSRM) suitable for traction drives, pump drives for hydraulic work functions, and generator operation. The motor features a resolver as a robust feedback sensor for rotor position detection and includes two PT1000 temperature sensors (one for stator winding temperature and one for coolant inlet temperature). The motor is designed to operate under severe environmental conditions with protection class IP6K9K, wide temperature range from –40°C to +100°C, and high mechanical load capability (shock resistance up to 50g, vibration resistance up to 10g).
