Product Description:
The MHD115C-058-PG1-BA servo motor is manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. Designed for closed-loop drive systems, the unit converts electrical energy into controlled mechanical rotation for positioning tables, pick-and-place heads, and conveyor sections. Integrated digital feedback allows the connected amplifier to read absolute rotor position, while the built-in brake keeps loads secure during power removal for demanding automation tasks.
With a continuous standstill torque of 70.0 Nm, the motor can deliver substantial stationary torque, and the holding brake is rated to the same level for static locking. Heat generated by winding code 058 is removed through natural convection, eliminating external cooling hardware. The specified operating window is 0 to 40 °C, and an enclosure rating of IP65 blocks dust and water jets. Accurate centering is provided by a 180 mm pilot diameter that mates with the square 192 mm flange. Power reaches the stator through a connector on side B, and a plain shaft with a seal transmits motion. Optically acquired digital servo feedback supplies rotor position information to the drive. The motor has size 115 and length C, and operation is permitted up to 1000 m above mean sea level.
The 192 mm flange mates directly with gearless axes and matches the 180 mm register without adapters. Closed-loop accuracy of ± 0.5 angular minutes is achieved by the optical encoder using absolute feedback for more than 4096 revolutions. Class F insulation permits winding temperatures up to 155 °C. During storage the unit tolerates −20 to +80 °C, easing inventory handling. The optically based measurement method avoids external sensors, and the output connector adheres to standard cabling.
