Product Description:
The MHD115B-058-PG1-RN belongs to the MHD Synchronous Motors series produced by Bosch Rexroth Indramat. As a servo motor it delivers closed-loop rotary motion for positioning axes, packaging stations, and transfer lines that need repeatable speed and torque. The integrated digital encoder feeds rotor position data to the drive, allowing the controller to synchronize motion with other devices in an industrial automation cell.
A centering diameter of 180 mm aligns the housing with machine frames, while the flange face measures 192 mm, giving a stable bolt pattern for the size 115 frame. The motor develops 50.0 Nm of continuous standstill torque, so it can hold heavy loads without overheating when stationary. Heat generated by that load is extracted through Liquid cooling, enabling higher continuous ratings than air-cooled designs. Power enters through a right-side Power connector, simplifying cable routing in cabinets arranged to the left of the axis. A Plain shaft is supplied, allowing direct coupling to gearboxes or pulleys without keyways that could introduce backlash. The built-in holding brake engages automatically when power is removed and is sealed from coolant by an internal shaft seal.
The brake supplies 70.0 Nm of static torque, so vertical or overhung loads remain fixed during an E-stop. Absolute feedback exceeding >4096 revolutions ensures the drive knows exact rotor angle after a power cycle, eliminating homing moves and reducing cycle times. Winding code 058 defines the electrical resistance and inductance values the compatible drive expects, while motor length B balances torque capability with envelope size for retrofit situations. Together, these attributes let the axis deliver precise, thermally stable motion control in continuous-duty production environments.
