The Bosch Rexroth Indramat MHD115B-058-PG1-BA is a servo motor from the MHD Synchronous Motors series. It features a plain shaft with a centering diameter of 180 mm and uses digital servo feedback with an integrated encoder for absolute position detection over more than 4096 revolutions. The motor provides a continuous torque at standstill of 50.0 Nm, includes a holding brake rated at 70.0 Nm, and is protected to the IP65 standard.
Internal Product Review
The MHD115B-058-PG1-BA is a servo motor with IP65 protection, well suited for demanding machine environments. Digital servo feedback with an integrated encoder and ±0.5 angular minute system accuracy support highly precise positioning. A 50.0 Nm continuous torque at standstill and a 70.0 Nm holding brake make the package especially attractive for controlled vertical-axis duty.

Product Description:
The MHD115B-058-PG1-BA is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for closed-loop control in industrial automation, the unit converts electrical energy into mechanical rotation while sending precise position data back to a drive controller. Its performance profile suits tasks such as axis drives in machining centers, packaging lines, and material-handling equipment where repeatable torque and speed are required. The motor is intended for applications that need stable motion, accurate feedback, and consistent response during continuous industrial operation.
The motor uses winding code 058, a plain shaft, and a power connector on side B of the housing. At standstill, it supplies a continuous torque of 50.0 Nm, and heat is removed by natural convection without external fans. The housing has an IP65 rating, which helps protect internal components from dust and water jets. Mechanical alignment is supported by a centering diameter of 180 mm and a flange measuring 192 mm. Class F insulation tolerates winding temperatures up to 155 °C, and the motor is intended for ambient conditions from 0 to 40 °C. An optically based digital servo feedback encoder supplies absolute position data, and installation is permitted at elevations up to 1000 m above mean sea level.
Axis holding is provided by an integrated brake that delivers 70.0 Nm of static torque when power is removed. For transport or long periods out of service, the motor can be stored at temperatures from -20 to +80 °C, and a shaft seal helps maintain internal lubrication. Closed-loop precision is held to ± 0.5 angular minutes, and multi-turn feedback over more than 4096 revolutions, listed as Absolute (>4096 revolutions), reduces the need for external homing switches. This feedback arrangement supports accurate position tracking on axes that rotate through many turns during normal machine movement.
