Product Description:

The MHD093A-035-NP1-BA is a permanent-magnet servo motor manufactured by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. It serves as the rotary drive element in automated machinery, delivering commanded speed and position profiles for packaging lines, transfer stations, and general handling systems. Mechanical integration is simplified by a 140/150 mm square flange, a 130 mm centering diameter, and size-093 laminations in the short A-length housing. The flange and centering features help seat the motor accurately on mating machine surfaces during installation.

A keyed shaft with a shaft seal transmits load while limiting contaminant ingress. The winding code 035 aligns electrical constants with compatible Rexroth drives, allowing a continuous standstill torque of 12.0 Nm. An internal brake supplies 22.0 Nm so vertical axes remain fixed when power is removed. The brake also supports load holding during shutdowns or power loss. Heat is removed through natural convection, and the windings use Insulation Class F. The enclosure is rated IP65, preventing dust and water jets from reaching live parts. Power is supplied through an output connector on side B, which helps reduce cable loops inside the cabinet.

The feedback system uses Digital servo feedback (HSF) with an optical measuring method to supply high-density incremental data to the drive controller. This feedback arrangement allows the drive to monitor rotor movement continuously during positioning and speed-controlled operation. Relative position detection pairs with a system accuracy of ± 0.5 angular minutes, enabling fine error compensation without external encoders. During operation, the motor maintains thermal stability between 0 to 40 °C, and it may be stored from -20 to +80 °C without degradation. Installation is permitted up to 1000 m above mean sea level for standard operation.
