Product Description:

The MHD115B-024-PP1-BA servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. It is an electromechanical actuator intended for high-duty positioning and velocity control in automated machines. By translating three-phase drive current into regulated rotary motion, the motor serves as the primary mechanical element in packaging stations, gantry axes, and material-handling cells where consistent torque and encoder-based feedback are required for repeatable cycles.

At standstill, the rotor can deliver 50.0 Nm of continuous torque, which indicates the sustained load the axis may hold without overheating. The housing meets IP65, so the internal windings remain protected from dust and low-pressure water jets during cabinetless mounting. Position data is generated by an integrated digital servo feedback encoder behind the shaft, allowing the drive controller to close speed and position loops without external sensors. The motor bolts to a machine plate through a 192 mm square flange and centers on a 180 mm pilot to maintain concentricity. Heat from copper losses is removed by natural convection, so no forced-air system is required. The motor uses insulation class F windings and a keyed shaft. It also uses optically based measurement, winding code 024, and power entry through an output connector on side B. The motor has size 115 and length code B, and it can be installed up to 1000 m above mean sea level.

An internal brake rated at 70.0 Nm locks the shaft when the drive is disabled or during vertical-axis emergencies. Motion precision is supported by a system accuracy of ± 0.5 angular minutes, so commanded positions are followed closely throughout the full revolution range. The feedback device records multiturn position as absolute feedback for more than 4096 revolutions, eliminating homing moves after power restoration. Normal operation is permitted at ambient temperatures from 0 to 40 °C, while storage between -20 °C and +80 °C helps protect the insulation when the machine is idle. A fitted shaft seal blocks lubricant migration along the keyed journal, and the class F insulation protects the windings during thermal cycling.
