Product Description:

The MHD115A-058-PP1-BA is a servo motor produced by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. Size code 115, length code A, and winding code 058 indicate the frame arrangement and winding selection for this version. In automated production lines, it converts drive commands into controlled rotary motion for positioning tables, transfer arms, or spindle attachments where precise speed and torque regulation are essential for cycle accuracy and repeatability. A keyed shaft interface simplifies coupling to gearboxes or belt pulleys and provides positive torque transfer without relying only on a clamping connection.

The motor’s mechanical envelope uses a 192 mm square mounting flange that mates with a 180 mm centering diameter, allowing rigid alignment on the machine frame. Rated mechanical output at standstill reaches 32.0 Nm of continuous torque, and the winding uses an Insulation Class F system for elevated internal temperature capability. The housing is sealed to IP65, so dust and low-pressure water jets do not affect internal components during normal industrial service. Position data are generated by an optical digital servo feedback encoder that supplies absolute rotor information to the drive controller. Power conductors exit on side B through an output connector, which helps keep cable routing clear of moving machine elements.

The motor operates in ambient temperatures of 0 to 40 °C, with storage permitted from -20 to +80 °C and installation altitude up to 1000 m above sea level. A permanent-magnet holding brake delivers 70.0 Nm to secure vertical loads when power is removed, and a shaft seal protects the output end. During motion, the feedback system achieves ±0.5 angular minutes of system accuracy while heat is released by natural convection. Absolute position tracking over more than 4096 revolutions allows the drive to retain position reference through power cycles and supports controlled restart behavior.
