Product Description:
The MHD112A-035-PG1-AN belongs to the MHD Synchronous Motors series developed by Bosch Rexroth Indramat. It is a permanently excited AC servo motor intended for closed-loop positioning and velocity control in automated machinery. By integrating digital feedback and a plain output shaft, the unit converts drive current into precise rotary motion under CNC or PLC command. This makes it a practical choice for feed axes, handling systems, and other machines that require accurate response during repeated motion cycles. Its 112 frame format and liquid-cooled construction make it suitable for continuous-duty equipment where stable thermal behavior and compact installation are important.
The motor carries an enclosure rating of IP65, so dust is kept out and water jets do not interfere with operation. At standstill, it can supply 15.0 Nm of continuous torque, which allows sustained loading during interpolation, holding, or tensioning tasks. Heat from this output is removed through liquid cooling, which helps keep winding temperatures controlled during long duty cycles. A factory-installed holding brake provides 22.0 Nm of static torque, allowing vertical or suspended loads to remain in place when power is removed. The permitted ambient range is 0 to 40 °C, which suits standard indoor industrial installations and supports stable operation within normal production environments.
A centering pilot of 130 mm helps align the motor concentrically on the machine interface. The optical feedback system provides an accuracy of ± 0.5 angular minutes, supporting repeatable positioning and stable speed control. It also offers absolute position over more than 4096 revolutions, so the controller can retain multi-turn position information after startup. Insulation class F allows winding hot-spot temperatures up to 155 °C. The motor also uses a 192 mm flange, a power connector on side A, and a shaft seal to support installation in enclosed industrial equipment.
