Product Description:

The MHD093B-058-NP1-BA is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It combines a permanent-magnet rotor with electronic commutation so that motion controllers can generate precise, closed-loop movement in automated machining cells, packaging lines, or material-handling axes. The motor’s keyed shaft transfers torque to couplings or pulleys, while a relative, optically based position sensor supplies high-resolution feedback to the drive. This arrangement supports repeatable speed regulation and positioning on axes that start and stop frequently.

Mechanical output at stall reaches 17.5 Nm, providing constant force for holding or low-speed indexing. A protection rating of IP65 blocks dust and water jets, allowing cabinet-free installation near the work zone. The integrated encoder uses digital servo feedback (HSF), giving the controller fine velocity and position data without external sensors. An electromagnetic brake applies 22.0 Nm when power is removed, securing vertical loads or tooling in place. Heat produced in the stator escapes through natural convection, so no external fan or liquid circuit is required. The motor has a 140/150 mm square flange, winding code 058, motor length B, and a power connector pointed toward side B for straightforward cable routing. A shaft seal is also present.

The motor uses Class F insulation, and continuous operation is specified between 0 to 40 °C. A centering pilot of 130 mm aligns the housing with gearboxes or mounts, and the motor maintains composite accuracy within ± 0.5 angular minutes when paired with the HSF encoder. Storage is permissible from −20 to +80 °C, and the unit can be installed up to 1000 m above mean sea level without derating. Because the encoder uses relative measurement, no absolute battery is required.
