Product Description:

The MHD115C-059-NG0-LN is a servo motor manufactured by Bosch Rexroth Indramat for inclusion in the MHD Synchronous Motors series. As a servo actuator, it converts drive output from compatible controllers into controlled rotary motion for positioning, velocity, and torque duties within automated machinery. The model belongs to motor size 115 and uses the C-length housing, giving it the mechanical envelope required for mid-range power tasks while remaining compatible with common flange-mounted machine arrangements.

Its continuous stall capability reaches 70.0 Nm, allowing stable torque delivery without thermal overload at zero speed. Heat generated under this load is removed through liquid cooling. A cooling jacket integrated into the housing circulates coolant to keep winding temperature within permissible limits during sustained operation. The stator is centered with a 180 mm pilot diameter, matching ISO flange tolerances so the shaft aligns accurately with gearboxes or couplings. Rotor position is monitored by a digital servo feedback (HSF) encoder, providing high-speed serial data for precise commutation and motion control. Electrical power enters through a power connector that supports shielded cables and locks against vibration.

The flange face measures 192 mm, supplying sufficient bolt-circle area for high-torque joints without adapter plates. A plain shaft transmits motion, and the factory-installed shaft seal helps keep lubricants in place while limiting contaminant entry. Position control uses relative position detection, so the drive performs a reference move after power-up before full positioning accuracy is available. The motor uses winding code 059, which corresponds to resistance and inductance values used by compatible MHD drives. Connections are oriented to the left side of the housing, which can simplify cable routing in line-mounted machines, and the unit is supplied without a holding brake when external locking is used.
