Product Description:

The MHD093C-058-NP1-AA belongs to the MHD Synchronous Motors series developed by Bosch Rexroth Indramat for electrically driven automation axes. The C-length frame and 093 size stator are combined to deliver medium power in compact machine spaces, while the keyed output shaft couples directly to gearboxes or pulleys. In production cells, this motor converts drive-controller current into rotational motion that positions tooling, conveyor sections, or indexing tables with repeatable accuracy. Its synchronous design supports controlled acceleration and stable operation in positioning and speed-controlled applications.

Rated for a continuous standstill torque of 23.0 Nm, the motor can support static loads without overheating under rated current. An integrated holding brake adds a counter-torque of 22.0 Nm so vertical or suspended axes remain fixed during power loss. Rotor position is monitored by Digital servo feedback (HSF), enabling high-resolution speed and position loops in Rexroth drive controllers. Winding code 058 sets the phase resistance and inductance to match the MHD power range. Heat generated in the windings is dissipated through the housing by natural convection, so unobstructed airflow around the frame is required for continuous operation. The motor reports relative position data, and the built-in shaft seal helps limit lubricant migration toward the feedback system.

Mechanical interfaces follow IEC dimensions: a centering pilot of 130 mm aligns the stator concentrically, while the mounting face corresponds to the 140 / 150 mm flange group for direct installation in existing servo assemblies. Power conductors exit the motor housing on side A, allowing cable trays to remain on one side of a multi-axis assembly and helping keep routing consistent in tightly packed machine frames. Torque is transmitted through a keyed shaft, which prevents slip during rapid reversals and works with standard keyed hubs. A shaft seal is fitted to help guard against coolant spray.
