Product Description:

The MHD115C-058-PP0-BN is a servo motor produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It is intended for axis drives in machining centers, printing lines, and material-handling stations, where it converts drive commands into accurate rotary motion that can be synchronized with adjacent axes. This type of motor is used where steady torque response and repeatable positioning are needed during indexing, feed control, and coordinated machine motion. The motor uses an IEC square-style frame, which supports straightforward installation in automation equipment and compatibility with Indramat drive hardware.

The motor supplies a continuous standstill torque of 70.0 Nm, allowing it to support substantial static loads without overheating. Heat at this operating point is removed by liquid cooling, which helps keep stator temperature stable during high-duty cycles and repeated acceleration sequences. Mechanical alignment uses a 180 mm centering pilot and a square flange measuring 192 mm, permitting direct mounting to large gearboxes or machine plates. Torque is transmitted through a keyed shaft that resists slip under reversing loads, while motion data are returned through integrated digital servo feedback. The unit is supplied without a holding brake, so any parked-load retention must come from the drive or an external device.

Winding code 058 matches compatible Indramat drive settings for this motor type and supports proper current delivery across the speed range. Position information is available as absolute feedback (>4096 revolutions), so the axis retains multi-turn position data after power loss and can return to operation without a reference run in many systems. Power cabling exits on side B through an output connector, and a shaft seal helps keep coolant or oil away from the encoder cavity. The motor uses frame size 115 with motor length C, giving it a large mechanical format suited to high-torque servo axes in compact machine layouts.
