Product Description:

The MHD115A-058-NG1-AA belongs to the MHD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a servo motor intended for closed-loop drive systems where precise rotary positioning is required in automated equipment. An optical measurement method works with relative position detection to relay shaft data to the controller. The integrated feedback channel helps the drive keep motion synchronized with commanded profiles during positioning and speed control.

This model delivers a continuous standstill torque of 32.0 Nm, indicating the static torque available at zero speed. Mechanical alignment during installation is supported by a 180 mm centering diameter behind a 192 mm square flange. The housing carries an IP65 rating that seals the internals against dust and low-pressure water jets. Rotor position is monitored by a Digital servo feedback (HSF) encoder, which supplies high-speed signals for tight velocity control. Heat removal relies on Natural convection, so no external fan is required within the 0 to 40 °C operating ambient range. Power enters on side A through an output connector, which can simplify cable routing where the connection side must remain accessible. This configuration uses motor size 115, motor length A, and winding code 058.

The holding brake generates 70.0 Nm of static torque, allowing the axis to stay locked when the drive is de-energized. Overall positioning repeatability is kept within ± 0.5 angular minutes, which suits precision tooling and indexing tasks. Storage temperatures from -20 to +80 °C help protect the insulation system during shipment or downtime, and the windings use insulation class F. A shaft seal is fitted to help prevent lubricant escape, and the maximum setup height is 1000 m above mean sea level. The plain shaft arrangement is suited to applications that use a direct coupling without a keyed shaft connection.
