MHD041A-144
The MHD041A-144 belongs to the MHD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a compact rotary unit used to drive axes that need position and speed regulation through a closed-loop controller. Within automated assembly cells, packaging lines, or pick-and-place stations, the motor converts electrical energy from an Indramat drive into controlled mechanical rotation. This supports repeatable starts, stops, reversals, and short indexing moves in machinery that depends on accurate servo response.
A centering pilot of 50 mm lets the housing seat precisely on aligned machine faces, while the square mounting interface measures 82 mm across. When the shaft is held at zero speed, the windings can maintain a continuous torque of 1.3 Nm, so the axis resists static process forces without extra clamping devices. Frame size 041 identifies a narrow stator diameter that reduces space requirements in multi-axis gantries. The 144 winding code indicates the phase resistance and inductance used by the matching drive amplifier so rated current can be supplied without oversaturation or control instability.
The axial build length marked A keeps overall motor depth short, easing installation in shallow enclosures or on slide carriages with limited stroke. As a closed-loop Servo Motor, the unit integrates the feedback needed for dynamic error correction, allowing the controller to command smooth velocity ramps and rapid indexing. It is intended for use with Bosch Rexroth Indramat drives, so current limits and commutation values are matched to the motor design. The MHD Synchronous Motors platform uses shared connectors, seal geometry, and cooling surfaces across multiple torque classes, which helps keep machine layouts consistent when a different output level is needed.
