Product Description:

The MHD112A-058-NP1-BN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for precision motion tasks, the unit delivers commanded torque and velocity to conveyor sections, pick-and-place heads, and forming tools while responding to position loops closed in the drive controller. Its shaft uses a keyway for positive torque transfer, and a shaft seal helps limit lubricant escape at the machine interface. Insulation class F windings tolerate winding temperatures up to 155 °C, which helps the motor handle repetitive industrial duty in automated production cells. This makes the motor suitable for axes that must start, stop, and reverse with controlled motion rather than simple constant-speed rotation.

It delivers a continuous stall torque of 15.0 Nm, providing steady holding force for vertical axes or tensioning drives. A sealed rating of IP65 prevents dust ingress and water jets from contacting internal laminations, so the motor can be mounted outside electrical cabinets. Heat is removed by liquid cooling, which helps control winding temperature during long operating periods and frequent load changes. The cooling circuit also reduces the need for external airflow around the housing. Rotor position is monitored by digital servo feedback (HSF), which supplies high-resolution incremental information to the controller for accurate speed and position regulation. The motor can operate across an ambient range of 0 to 40 °C without derating, which broadens installation options in enclosed or climate-controlled equipment.

During an emergency stop or power loss, the integrated brake can hold the shaft with 22.0 Nm of torque, helping prevent load drift on suspended axes. Closed-loop accuracy is aided by a system error band of ± 0.5 angular minutes, which supports repeatable indexing in multi-station assemblies and synchronized transfer systems. Alignment to driven equipment is simplified by a centering pilot of 130 mm on the 192 mm mounting flange, while a permissible setup altitude of 1000 m above mean sea level keeps thermal behavior predictable in most factory locations. Power leads exit through a connector on side B, which can simplify cable routing when the motor is installed near guards or machine frames. The feedback head uses optical sensing for relative position detection.
