Product Description:

The MHD115A-024-NP0-AA is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is designed to deliver controlled rotary motion to automated axes, handling positioning tasks where digital loop feedback is required. Within an automation cell, the motor couples to a drive controller, translating commanded current into precise shaft torque for conveyors, gantries, or tool spindles.

This model supplies a continuous standstill torque of 32.0 Nm, providing the steady mechanical force needed for holding or slowly moving loads without overheating. The enclosure carries an IP65 rating, so dust ingress and low-pressure water jets do not affect internal components. A centering diameter of 180 mm aligns the 192 mm square flange against the machine frame, keeping runout minimal. During long-term storage, the unit tolerates air temperatures from -20 to +80 °C, protecting insulation and bearings before installation. Position data comes from a digital servo feedback (HSF) encoder that uses an optical measurement method and achieves ±0.5 angular-minute system accuracy, enabling fine interpolation in multi-axis assemblies. Additional design points include a keyed shaft for positive torque transfer, winding code 024, motor size 115 with length code A, and power conductors routed to side A through an output connector.

The operational envelope extends from 0 to 40 °C, matching typical cabinet cooling limits, while heat is removed solely by natural convection, so no blower maintenance is required. Class F insulation withstands 155 °C winding temperature, ensuring dielectric strength during cyclical duty. A protected shaft seal blocks oil or coolant from the bearing cavity, complementing the keyed shaft design. The motor is supplied without a holding brake, making it suitable for applications where drive torque or external mechanics secure the load. Relative position detection simplifies homing routines, and installation is permitted up to 1000 m above mean sea level.
