Product Description:

The MHD093B-058-PG0-BN is a servo motor built by Bosch Rexroth Indramat and supplied within the MHD Synchronous Motors series. Designed for closed-loop motion axes, it couples directly to machinery where accurate speed and torque control is required for packaging, material handling, or robotic cells. The unit’s permanent-magnet rotor works with a matching drive controller to provide rapid positioning without mechanical transmission slack. Its plain shaft is ready for coupling to gearboxes or timing pulleys used on automated production lines. This arrangement supports accurate indexing, transfer, and point-to-point positioning in automated equipment.

The motor uses the 093 size and B length code, with a mounting centering diameter of 130 mm and a flange interface rated IP65 against dust and water jets. Continuous torque at standstill reaches 17.5 Nm, and the housing uses liquid cooling to remove heat. The stator windings use the 058 code and are insulated to Class F for a 155 °C conductor limit. Feedback comes from a digital servo encoder with an optical measuring method and absolute position storage for more than 4096 revolutions. Power cables exit through a connector on side B, and a shaft seal helps prevent lubricant leakage. This model is supplied without a holding brake, so static load retention must be provided externally.

The motor operates in ambient temperatures from 0 to 40 °C, and it may be stored in a dry location from −20 to +80 °C without affecting insulation or encoder performance. System accuracy is specified at ± 0.5 angular minutes, which helps minimize positioning error in multi-axis gantries. Installation is permitted up to 1000 m above MSL; above that height, cooling capability and dielectric clearances must be reduced. A dual-pattern flange of 140 / 150 mm supports a wider range of machine interfaces while keeping the centering lip engaged for precise alignment. Dry storage conditions also help protect the motor during periods before installation.
