Product Description:

The MHD115C-058-PG0-BA is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is intended for closed-loop motion axes where precise speed and position control are required in gantries, machining centers, or packaging lines. This C-length, size 115 unit uses a plain shaft for direct coupling and routes power through a connector on side B, which can simplify cabinet layout. An integrated digital servo feedback encoder provides absolute position information, reducing the need for external reference sensors at startup. This arrangement supports direct feedback to the drive for accurate velocity and position regulation during motion.

The motor delivers a continuous standstill torque of 70.0 Nm, allowing it to hold heavy loads without overheating. A centering diameter of 180 mm and a flange size of 192 mm support rigid mounting that helps maintain alignment under dynamic forces. Its enclosure carries an IP65 rating, and a shaft seal helps keep lubricants in and contaminants out. Operation is permitted at ambient temperatures from 0 to 40 °C. Storage is permissible from -20 °C to 80 °C, and the unit can be installed at sites up to 1000 m above mean sea level. It is supplied without a holding brake, so vertical axes require external mechanical restraint or drive torque when power is removed.

An F-class winding insulation rated F permits higher allowable winding temperatures, which increases thermal headroom during intermittent overloads. Position accuracy is maintained within ± 0.5 angular minutes, and the optical feedback system supports a position detection range of more than 4096 revolutions before rollover. The housing relies on natural convection for heat dissipation, avoiding the extra wiring required by forced-air or liquid cooling. The optical measuring method supports closed-loop operation with compatible IndraDrive amplifiers. This feedback arrangement helps the motor maintain stable position tracking across multi-turn operation.
