Product Description:

The MHD112B-048-NG0-LN is a servo motor developed by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Intended for positioning and velocity control on automated assembly lines, it converts regulated electrical power into precise rotary motion that the machine controller can modulate in real time for repeatable closed-loop operation. It is well suited for axes that require controlled acceleration, stable running speed, and accurate stopping during repetitive machine cycles. When paired with a compatible drive, the motor can support coordinated motion in transfer systems, indexing tables, and handling equipment.

At standstill, the motor delivers a continuous torque of 28.0 Nm, allowing it to hold loads securely during dwell periods. Heat generated under sustained duty is removed by liquid cooling, so full torque remains available throughout the 0 to 40 °C operating range. The housing meets IP65, sealing internal components against dust and low-pressure water jets. A flange diameter of 192 mm sets the mounting pattern, while the frame is further characterized by size 112 and length code B. Copper windings are insulated to Class F, permitting winding temperatures up to 155 °C. Electrical characteristics correspond to winding code 048, and power is supplied through a left-facing power connector that simplifies routing inside compact cabinets.

Accurate mechanical alignment is achieved with a centering pilot of 130 mm, which helps minimize radial runout between the plain shaft and coupled equipment. Rotor position is monitored by digital servo feedback (HSF) that uses an optical measuring method and reports relative position to the drive. This feedback supports a system accuracy of ± 0.5 angular minutes for fine contour control. The motor is supplied without a holding brake, relies on an internal shaft seal to help prevent lubricant escape, and can be stored safely between -20 to +80 °C. Installation is permitted up to 1000 m above mean sea level, and the relative detection scheme maintains consistent resolution during temperature shifts and process cycles.
