Product Description:
The MHD093C-058-NP1-BN is a three-phase synchronous servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for axis modules in packaging machines, handling systems, and printing lines, the unit converts drive current into controlled rotary motion with high positional repeatability. It links directly to Rexroth digital drives, providing closed-loop torque and velocity control that supports accurate starts, stops, and speed changes in automated equipment.
At stall, the motor can deliver 23.0 Nm of continuous torque, which is the maximum load it can hold without overheating. The centering diameter is 130 mm, so the mounting surface must match this pilot diameter to keep the shaft aligned during operation. Heat leaves the stator through liquid cooling, which allows higher RMS current than comparable air-cooled frames. A dual-pattern flange of 140 / 150 mm provides two bolt-circle options for machine integration. Electrical behavior is matched by winding code 058, which sets the voltage constant and allowable current for the paired drive. The keyed shaft transmits torque without slip, and the 093 frame size gives the motor inertia suited to medium-duty indexing and repeated motion cycles.
The integrated holding brake supplies 22.0 Nm of static torque, so vertical or suspended axes can remain in place when power is removed. Rotor position is monitored by digital servo feedback (HSF), which returns high-resolution incremental data and supports the relative position detection method used during homing. Body length code C increases active copper volume, which helps raise peak torque while keeping the same flange outline. Power and protective ground conductors exit on side B, and the factory-fitted output connector simplifies cable connection by eliminating internal hard-wiring. This arrangement supports compact machine layouts where cable routing space is limited and stable feedback is required throughout frequent acceleration and deceleration.
