Product Description:

The MHD112B-058-PP2-BN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It converts electrical energy supplied by matched drive controllers into controlled mechanical rotation for positioning and feed axes in industrial automation. The motor combines a keyed shaft, an integrated absolute encoder, and a factory-installed holding brake for closed-loop motion control on machines that require high accuracy and repeatability. This arrangement also supports stable speed regulation and accurate position feedback during repeated axis movements.

At standstill, the motor can supply 28.0 Nm of continuous torque, giving it the ability to resist load without overheating during static clamping or low-speed feed operations. The housing carries an IP65 rating, so dust ingress is prevented and water jets do not affect internal components. Heat generated by the stator windings is removed through liquid cooling; coolant channels in the housing keep the winding temperature below insulation class F limits during extended duty. A flange size of 192 mm sets the bolt circle for mechanical mounting, while the optical digital servo feedback system reports rotor position with a system accuracy of ± 0.5 angular minutes to the drive for tight position loops.

A centering pilot of 130 mm aligns the housing precisely to the machine frame, and the integrated holding brake supplies 32.0 Nm to lock the shaft when power is removed. The multiturn position detector provides absolute position feedback for more than 4096 revolutions, so the machine control retains axis reference without homing after power cycles. The permitted ambient operating range is 0 to 40 °C; outside this range, derating or separate enclosure conditioning is required. Power leads exit on side B through an output connector, and a shaft seal is fitted to protect internal bearings from coolant splash or lubricant mist.
