Product Description:

The MHD115A-058-NP1-BN servo motor is produced by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. It is a brushless AC drive element used for closed-loop axis control in industrial automation, where repeatable rotary positioning and steady torque are required. The motor’s keyed shaft mates with couplings or gearboxes to actuate conveyors, gantries, and forming tools, while its integrated feedback device allows the associated controller to command tight velocity and position profiles during continuous or cyclic duty.

The unit delivers a continuous standstill torque of 32.0 Nm, letting machinery hold or accelerate medium-inertia loads without overheating. A centering diameter of 180 mm aligns the frame, and the flange face measures 192 mm for ISO-pattern mounting. The housing is sealed to IP65, and heat is removed through liquid cooling, so the stator can operate at elevated current density. The windings are insulated to Class F, allowing winding temperatures up to 155 °C. The power lead exits on side B through an output connector, which helps with cable routing in compact cabinets. Winding code 058 identifies the electrical constants used with compatible Indramat drives, and the A motor length in size 115 keeps the package compact. Digital servo feedback (HSF) with optical measurement supplies high-speed position data, while relative position detection supports homing routines. Installation is permitted up to 1000 m above mean sea level, and a shaft seal protects the bearings.

A holding brake rated at 70.0 Nm secures vertical or load-bearing axes when mains power is absent. The motor can operate in ambient temperatures of 0 to 40 °C and may be stored at -20 to +80 °C without damage to the windings or magnets. System precision is reinforced by a positioning accuracy of ±0.5 angular minutes, making the device suitable for indexing tables and multi-axis synchronizing tasks.
