Product Description:

The MHD093B-058-NP0-BA is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is installed in automated machining centers, packaging lines, and material-handling axes where closed-loop drives are required to position loads with high repeatability. Its synchronous design allows the connected drive to regulate position and speed with consistent response during repeated starts and stops. The motor’s 093 frame size and B length provide medium inertia while remaining compact, and its keyed shaft transmits torque directly to pulleys or couplings without additional fixtures.

Under continuous stall conditions, the motor can deliver 17.5 Nm of torque, giving machines stable holding force for low-speed cuts or index moves. A centering diameter of 130 mm mates the housing accurately to precision flanges, and the standard mounting interface measures 140 / 150 mm for compatibility with common IEC adapters. Heat is removed through natural convection, so no forced-air blower is integrated and surrounding airflow must carry away stator heat. Winding code 058 identifies the electrical characteristics used with the matching drive so current can be regulated correctly. This arrangement supports stable low-speed operation without adding external cooling hardware to the motor body.

The unit is supplied without a holding brake, so applications that need static load retention must use drive torque or an external brake. Rotor feedback is provided by digital servo feedback (HSF), and the incremental signal uses a relative measuring principle that supports homing at power-up. Power leads exit to side B through an output connector, which helps keep cabling clear of nearby moving parts. A shaft seal is fitted to limit lubricant migration, and the housing supports natural cooling without fins. The smooth exterior is easy to wipe down in production environments where dust, residue, or light surface contamination may collect during normal machine operation.
