Product Description:
The MHD112B-058-NG1-AN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. The unit converts electrical energy into controlled mechanical motion for positioning tasks in automated machinery lines, where closed-loop velocity and torque regulation are required. Its construction supports integration with Indramat drive controllers, allowing precise axis control in packaging, material handling, and general factory automation.
At standstill, the rotor can deliver a continuous torque of 28.0 Nm, giving the drive adequate holding force for static loads without thermal overload. Heat generated by this load is removed through liquid cooling, so the stator maintains thermal equilibrium even during extended duty cycles. The housing has an ingress rating of IP65, meaning dust-tight sealing and resistance to low-pressure water jets, which is useful in washdown or particulate environments. A 192 mm square mounting flange aligns the motor with standardized machine faces, while the internal hollow-shaft encoder provides digital servo feedback (HSF) for high-speed position sampling that supports rapid control loop updates.
Dynamic positioning accuracy is supported by a holding brake that clamps the shaft with 22.0 Nm of static torque, preventing drift when power is removed. The motor uses Class F insulation, so winding temperatures up to 155 °C are permissible without loss of dielectric strength. When combined with the optical measurement system, the drive reaches a repeatable precision of ±0.5 angular minutes, which is suitable for multi-axis gantries installed up to 1000 m elevation. Reliable service is maintained across an ambient range of 0 to 40 °C, and a shaft seal protects the plain shaft interface against coolant ingress during continuous production cycles.
