Product Description:
The MHD093C-058-PG0-RA is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed as a torque source for positioning and speed-controlled axes, this motor can be coupled directly to industrial loads such as gantry drives, conveyors, and packaging machinery. That arrangement is common in machinery where the motor is mounted close to the load to reduce backlash and improve response. In automated systems, it serves as the rotary output element for axes that must start, stop, and reverse with controlled torque. It converts drive current into precise mechanical rotation and returns position data to the control system, supporting stable closed-loop motion during acceleration, indexing, and steady-speed operation.
The unit supplies a continuous standstill torque of 23.0 Nm through a plain shaft with a shaft seal, making it suitable for direct mechanical coupling in enclosed machine layouts. Mounting uses a centering diameter of 130 mm and a flange pattern of 140 / 150 mm, which helps the motor align accurately within the 093 frame. The housing has an IP65 rating and uses natural convection for cooling, so surrounding air can remove heat without a fan. Power enters through a right-side connector matched to the 058 winding, and the motor has no holding brake. This layout keeps cable entry on one side of the housing and leaves the drive end clear for the connected machine element.
Control precision is supported by a system accuracy of ± 0.5 angular minutes, measured by an optical method and paired with Absolute (>4096 revolutions) position data from the integrated encoder. This feedback arrangement allows the control system to maintain position information across multiple shaft turns without relying on a separate external sensor. The windings can operate continuously in ambient temperatures from 0 to 40 °C, while storage is permitted from -20 to +80 °C and installation is allowed up to 1000 m above sea level. An insulation rating of F supports winding temperatures consistent with Class 155 limits. The motor also uses digital servo feedback and has a length code of C.
