Product Description:
The MHD131B-024-NG0-BN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It converts drive controller commands into precise rotary motion for positioning axes, indexing tables, and spindle functions in industrial automation. Position data are captured by an optical feedback system that uses a relative detection method, allowing the connected drive to regulate speed and position during dynamic motion. This arrangement helps the axis follow commanded acceleration ramps, maintain steady running speed, and stop repeatably at target positions. Winding code 024 identifies the electrical layout used by this 131-frame motor and matches it to compatible inverters.
At standstill, the motor can sustain a continuous torque of 48.0 Nm, allowing loads to be held without excess heating. Heat is removed through an internal jacket that supports liquid cooling, which permits higher duty cycles than air-cooled housings and helps stabilize thermal behavior during repetitive operation. An enclosure rating of IP65 protects the windings from dust and water jets in industrial settings. Mechanical alignment is supported by a centering diameter of 250 mm and a square flange measuring 260 mm. The motor uses a plain shaft with a shaft seal, and the power conductors exit through a connector on side B for straightforward cable routing away from the mounting face.
The optical encoder provides Digital servo feedback (HSF), enabling closed-loop regulation to a system accuracy of ± 0.5 angular minutes. Rated performance is maintained across an ambient range of 0 to 40 °C, and the unit can be stored between -20 °C and 80 °C when not in service. Insulation to class F supports winding temperatures up to 155 °C during normal thermal loading. Because the feedback method is relative, the axis normally establishes its reference position during the machine homing sequence. The motor is supplied without a holding brake, so any required holding function must be provided externally, and motor length B keeps the stack compact while supporting installation heights up to 1000 m above sea level.
