Product Description:

The MHD112A-058-NG1-AN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Intended for precision positioning axes, the unit converts drive current into controlled rotation while a built-in optical feedback element transmits shaft data to the motion controller. Its mounting pattern and plain shaft allow direct coupling to gearboxes, making it suitable for packaging, printing, and material-handling lines where continuous duty and tight speed regulation are required.

The motor delivers a continuous standstill torque of 15.0 Nm, enabling it to hold loads without overheating when the axis is motionless. The motor is sealed to IP65, so dust and low-pressure water jets do not impair operation inside a cabinet or on open machinery. Heat is removed through liquid cooling, which keeps winding temperature below the Class F limit during sustained high current. The square mounting face uses a 192 mm flange, which provides compatibility with standard IEC adapters. Position feedback is obtained from a digital servo feedback (HSF) encoder, which supplies high-resolution incremental data for rapid loop closure. Additional details include winding code 058, insulation class F, and a power connector oriented toward side A for straightforward cable runs.

A spring-applied holding brake provides 22.0 Nm of static torque to secure vertical or suspended loads during power loss. Positioning accuracy is maintained within ± 0.5 angular minutes, allowing the axis to repeat commanded positions with minimal deviation. Mechanical alignment is simplified by a centering diameter of 130 mm. The motor operates continuously in ambient temperatures from 0 to 40 °C, and storage is permitted between −20 and +80 °C. Operation is supported up to 1000 m above mean sea level, a shaft seal helps prevent lubricant escape, and relative position detection complements the encoder after restart.
