Product Description:
The MHD115A-058-PP0-BA is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It pairs an integrated digital servo-feedback encoder with absolute position detection that extends beyond 4096 revolutions, enabling closed-loop motion control in assembly cells, gantries, and indexing stations. By linking the drive electronics to the mechanical load, the motor delivers precise speed and position regulation required for repeatable industrial automation. This feedback arrangement allows the drive to compare commanded motion with actual rotor position throughout acceleration, constant-speed operation, and stopping sequences.
At standstill, the motor delivers a continuous torque of 32.0 Nm, providing stable holding force on vertical or high-inertia axes. Its housing carries an IP65 degree of protection, sealing the windings and bearings against dust and water jets encountered on production floors. A centering diameter of 180 mm and a flange size of 192 mm align the stator accurately to gearboxes or machine frames. The stator windings use Class F insulation, which supports operating temperatures up to 155 °C. Operation is permitted in ambient temperatures from 0 to 40 °C, and heat is released through the ribbed aluminum frame without forced ventilation.
Cooling relies on natural convection, allowing installation without external blowers even at a maximum setup height of 1000 m above mean sea level. Power is transferred through a keyed shaft that helps prevent slip, and a shaft seal is fitted to keep contaminants out of the bearing cavity. Optical scanning inside the absolute encoder yields system accuracy of ± 0.5 angular minutes, which helps reduce positioning error in coordinated multi-axis assemblies. The motor is supplied without a holding brake, and its power leads exit through a connector on side B. It can also be stored safely between -20 °C and +80 °C when the machine is not in operation.
