Product Description:

The MHD115A-024-NP1-AA is a servo motor manufactured by Bosch Rexroth Indramat and part of the MHD Synchronous Motors series. Intended for tightly controlled industrial axes, the unit transforms drive current into regulated torque and speed so that machine tools, packaging equipment, and material-handling systems can position loads with repeatable accuracy. Relative position detection simplifies homing during startup and helps the control system reestablish a reference position after power is restored. That combination supports accurate positioning moves and stable speed regulation during continuous machine operation.

At the mechanical interface, the motor bolts to a machine frame through a 192 mm square flange and centers on a 180 mm pilot to keep the rotor coaxial with the driven load. Continuous stall capability is rated at 32.0 Nm, delivering the baseline torque needed during static holding or low-speed feed moves. Rotor feedback is supplied by digital servo feedback (HSF), which uses an optical method for high-resolution signal generation and gives the drive precise position information during closed-loop operation. Heat dissipates through natural convection, and the enclosure is sealed to IP65 to keep out dust and low-pressure water jets. The motor has length code A in size 115, a keyed output shaft with a shaft seal, and power conductors that exit on side A through an output connector for straightforward cable routing.

A built-in brake provides 70.0 Nm of holding torque, letting vertical or indexing axes remain locked when the inverter is disabled. Electrical insulation meets Class F limits, and overall motion precision reaches ± 0.5 angular minutes once the encoder is referenced. The stator is wound to pattern 024, matching the electrical values expected by compatible Rexroth drive amplifiers. The motor operates in ambient temperatures from 0 to 40 °C, can be stored between -20 and 80 °C, and functions without derating up to 1000 m above mean sea level.
