Product Description:
The MHD093B-035-NG1-BN is a rotary servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It converts electrical power from a drive controller into tightly regulated torque and speed, letting automated lines position axes, indexes, or spindles with consistent precision. The motor’s closed-loop design and high-speed feedback make it suitable for packaging machines, gantry loaders, or metal-cutting heads that require repeatable motion under variable loads.
Its mechanical interface follows a centering diameter of 130 mm and a 140 / 150 mm square flange, allowing standard face mounting. The plain shaft can deliver a continuous stall torque of 17.5 Nm, while a holding brake rated at 22.0 Nm secures the load when power is removed. Position data are provided by an HSF digital servo encoder that uses an optical scanning method and reports relative displacement to the controller. Power cables exit on side B through an output connector, keeping installation clear of moving parts. Thermal stability is maintained by liquid cooling; coolant circulating through the housing removes losses before they reach the stator laminations. The sealed enclosure is classified at IP65, stopping dust and water jets from reaching internal components during wash-down or debris-laden operation.
The operating envelope spans 0 to 40 °C, with safe storage from -20 to +80 °C, and functionality remains unchanged up to 1000 m above mean sea level. Class F insulation supports the winding temperature limits associated with continuous industrial duty. Closed-loop repeatability is enhanced by a system accuracy of ± 0.5 angular minutes, helped by a shaft seal that augments the enclosure against fluid ingress. Size code 093, length code B, and winding code 035 specify the stator geometry and electrical characteristics used for drive tuning.
