The Bosch Rexroth R911280584 (MHD093B-035-NG0-BN) is a synchronous servo motor engineered for high-dynamic motion applications. It features electronic commutation with four pole pairs and permanent magnets, supporting repeated high-frequency start-stop cycles. The motor operates within a voltage range of 350–396V AC and a frequency of 167 Hz. In naturally cooled operation, it delivers 17.5–20Nm torque at 12.8–15.1A; with liquid cooling, it achieves 33.3Nm torque at 24.3A continuous current and requires 1.3 l/min coolant flow to dissipate 900W of heat. The unit uses a B05 flange with a plain shaft, centering diameter of 130 mm, and is equipped with digital servo feedback HSF encoder for relative position detection. It includes shaft sealing, a B-side output power connector, and lacks a holding brake. The installation temperature range is 0 to +40°C.
