Product Description:

The MHD093B-058-NP1-BN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It converts three-phase drive power into controlled mechanical motion for pick-and-place modules, machining centers, and packaging equipment. Through integrated feedback and matched winding design, the unit supports synchronized positioning tasks that demand consistent torque delivery over extended duty cycles. This design also helps maintain stable response during repeated start-stop cycles and coordinated axis motion.

The motor supplies a continuous standstill torque of 17.5 Nm, so static load can be held without additional gearing while the drive current stays within continuous limits. An enclosure rating of IP65 seals the stator against dust ingress and low-pressure water jets, allowing installation outside a cabinet. Heat is extracted through liquid cooling, meaning coolant channels in the housing carry thermal energy away and keep winding temperatures below the Class F limit. Rotor alignment is referenced to a centering pilot of 130 mm, and the mounting interface follows a square flange footprint of 140/150 mm. Digital servo feedback (HSF) delivers high-resolution rotor position to the drive through an optical measuring method, supporting fast control loops and accurate speed regulation during contouring and indexing.

A holding brake integrated into the rear housing supplies 22.0 Nm of static torque, so vertical axes remain locked when power is removed. Position repeatability is supported by a system accuracy of ± 0.5 angular minutes, which works with the relative position detection scheme to enable fine incremental moves. Ambient ranges from -20 to +80 °C for storage and 0 to 40 °C during operation permit staging and service in ordinary factory climates. The shaft is keyed and protected by a positive shaft seal, while Class F insulation tolerates high winding temperatures under transient overload. Wiring exits on side B through an output connector, and installation is permitted up to 1000 m above mean sea level. This layout also supports straightforward cable routing in compact machine frames.
