Product Description:

The MHD112C-058-PG0-BN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is intended for closed-loop motion control where precise positioning and steady velocity regulation are required across automated machinery. The integrated feedback device works with a compatible drive so the motor can support coordinated motion in packaging equipment, material-handling axes, and other industrial systems that need repeatable rotary response. Its synchronous design also supports accurate response to command changes during repeated start, stop, and speed-holding cycles.

The motor seats against machinery with a centering diameter of 130 mm, which aligns the flange accurately with the mounting pilot. At standstill, it can deliver a continuous torque of 38.0 Nm, giving the axis stable output for constant loads. A square flange measuring 192 mm provides the attachment pattern and spreads reaction forces into the machine frame. Internal channels circulate coolant through the housing, and liquid cooling removes heat directly from the stator for stable performance in compact enclosures. Electrical characteristics follow winding designation 058, so the matching drive can apply the correct current parameters. The motor also uses size 112, length C, and a power connector on side B to support straightforward installation and cable routing. That connector position can also reduce cable crowding when the motor is mounted close to guarding or adjacent axis hardware.

The output uses a plain shaft that fits clamp or shrink-fit couplings, and a shaft seal helps protect the internal bearings from splash exposure. Position data come from feedback with absolute resolution of more than 4096 revolutions, and digital servo feedback lets the controller recover rotor position after power cycles without a separate reference run. This feedback arrangement helps the drive maintain commutation and position tracking during startup and normal operation. The unit is supplied without a holding brake, so any load that must remain fixed at standstill requires holding torque from the drive or an external mechanical restraint. Because the shaft is smooth, torque transfer depends on the selected coupling rather than a keyed connection.
