Product Description:

The MHD115B-024-PP1-RA is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Intended for closed-loop positioning and velocity control, it delivers regulated rotary motion to axes, gantries, and transfer stations throughout automated manufacturing cells. A keyed shaft transmits the drive torque, while an integrated optical encoder feeds position data to the drive controller for precise path execution.

Its continuous stall capability reaches 50.0 Nm, allowing the motor to support static loads without thermal overload. The housing carries an IP65 rating, so dust and low-pressure water jets cannot reach internal windings or bearings. Position data are generated by a digital servo feedback unit that sits inside the housing and communicates absolute angle information to the motion controller. A square 192 mm flange with a 180 mm pilot aligns the stator to the machine frame, and the spring-applied brake delivers 70.0 Nm of holding torque to secure vertical axes when power is removed. The optical measurement method supports accurate position detection, and winding code 024 indicates the resistance and inductance values used for medium-speed applications.

Thermal management relies on natural convection, so unobstructed airflow around the ribbed housing is required inside the 0 to 40 °C operating range. Class F insulation permits elevated winding temperatures during dynamic duty cycles without compromising dielectric strength. System precision is specified at ± 0.5 angular minutes, and the feedback remains absolute (>4096 revolutions), eliminating homing after power cycles. The motor may be stored between -20 and +80 °C, installed up to 1000 m above mean sea level, and mounted using its B-length, size 115 frame. A shaft seal keeps lubricant inside the bearing cavity, completing the protective envelope for general-purpose industrial service.
