Product Description:
The MHD112C-024-NP0-LN synchronous motor is produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. This servo unit is intended for drive packages that require acceleration, repeatable speed control, and closed-loop positioning on gantries, machine tools, and packaging stations. It occupies the 112 size envelope with a C-length stator and uses a left-hand power connector that couples directly to the associated inverter. By delivering controlled torque on demand, it serves as the rotational element in precise industrial automation loops. Its design suits axes that must start, stop, and reverse direction without losing positional consistency. This makes it suitable for coordinated motion where the drive must respond quickly to changing commands.
Its mechanical interface uses a centering shoulder of 130 mm and a flange that measures 192 mm across, allowing rigid attachment to gearboxes or machine frames. The motor can supply 38.0 Nm of continuous standstill torque, so it can hold load force at zero speed without thermal overload under rated operating conditions. Heat generated in the windings is removed by liquid cooling, which supports higher continuous current than air-cooled designs. For feedback, a digital servo feedback (HSF) encoder sends position data to the controller, and the system uses relative detection rather than absolute tracking. The motor is supplied without a holding brake, which helps reduce rotating mass.
The motor uses 024 windings, which establish the voltage constant and thermal behavior used for drive matching. The frame size of 112 is paired with a rotor that uses a keyed shaft, providing secure mechanical coupling to pulleys or couplings. A shaft seal is fitted to help protect the motor interior from coolant and other contaminants during machine operation. Cabling enters through a standardized power connector, and signal connections are routed on the opposite face to keep surrounding space more open. Because the feedback system is relative, the axis must be homed at startup before full positioning accuracy is available. After referencing, the motor can repeat commanded motion in normal servo operation.
