Product Description:

The MHD090B-058-NP1-UN is a servo motor manufactured by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. In automated production cells, it converts drive current into precise rotary motion so indexing tables, gantry axes, or carton erectors can reach commanded positions with controlled acceleration and settling. Its medium-frame housing fits the 090 platform with a B-length stator core, giving the motor a compact form for machines that need strong dynamic response without excessive installation space. Closed-loop operation also helps the axis remain stable when load conditions change during repetitive cycles.

The motor supplies 12.0 Nm of continuous standstill torque when the stator is held at rated temperature. Position feedback is generated by digital servo feedback (HSF), allowing the connected drive to monitor rotor movement with fast signal processing. Accurate centering is established by a 110 mm pilot diameter, and a square 140 mm mounting flange supports secure attachment to the driven machine. Heat is removed through liquid cooling, which moves thermal energy away from the housing during sustained duty. This cooling method supports stable operation where cabinet air circulation is limited or ambient heat is high.

For static holding or emergency shutdowns, an integrated brake provides 11.0 Nm of holding torque and engages automatically when power is removed. The power and feedback connector assembly is turnable through a range of 270°, which helps route cables around guards, panels, or adjacent axes. Output torque is delivered through a keyed shaft, and the motor uses relative position detection for motion feedback referenced to the last datum. A shaft seal helps protect the bearing cavity from contamination, and the combined connector layout keeps power and feedback connections organized at the motor housing.
