Product Description:

The MHD112A-024-PP1-BN belongs to the MHD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a brushless AC servo motor used to drive machine tool spindles, gantry axes, and other positioning modules where high dynamic accuracy is required in industrial automation. A liquid-cooled housing, an integrated absolute encoder, and a keyed output shaft allow the motor to supply controlled torque while maintaining thermal stability and reliable mechanical coupling inside sealed cabinets and multi-axis assemblies.

When clamped motionless, the motor can supply a continuous torque of 15.0 Nm, giving drive controllers a stable working reserve for process loads that must be held without rotor movement. Accurate mounting is assisted by the centering diameter of 130 mm, and the interface bolts to a square flange that measures 192 mm across. Heat produced by copper losses is extracted through liquid cooling, so the stator temperature remains low even at high cycle rates. Power leads exit on the rear face and terminate on side B, simplifying cable routing in cabinets where multiple motors share a common trunk. The A-length frame and size-112 lamination stack keep overall mass moderate while still accommodating the winding code used with medium-voltage servo inverters.

For static safety, a holding brake generates 22.0 Nm of locking torque, preventing back-driving on vertical or suspended axes during power loss. Position feedback is provided by digital servo feedback; the signal originates from an internal multi-turn encoder with absolute tracking for more than 4096 revolutions, so homing routines are unnecessary after power-up. Mechanical power is transmitted through a keyed shaft, and a shaft seal is fitted to limit lubricant escape and particle ingress. The power terminals use an output connector for direct cable connection.
