Product Description:
The MHD115B-024-NP0-BN servo motor belongs to the MHD Synchronous Motors series from Bosch Rexroth Indramat. It is designed as a closed-loop drive element that converts commanded current into precise rotary motion for positioning, indexing, and speed-regulated tasks in automated machinery. This type of motor is commonly used on axes that require accurate starts, stops, and speed changes during repeated machine cycles.
The unit delivers 50.0 Nm of continuous torque at standstill, which supports heavy inertial loads during holding phases. Heat generated under this load is removed by an integrated liquid cooling jacket, so rated performance can be maintained even inside sealed enclosures. The enclosure carries an IP65 protection rating, which helps keep dust and water jets away from the internal windings. Proper operation is allowed from 0 to 40 °C, while storage is limited to -20 to +80 °C. The motor mounts through a 192 mm square flange with a 180 mm centering pilot, matches size code 115, and uses length code B for its stack depth. A keyed shaft with an installed shaft seal transfers torque while limiting lubricant escape. The motor comes without a holding brake, and the power connector is oriented toward side B with an output connector interface. Insulation class F permits winding temperatures up to 155 °C, and the motor can be installed at elevations up to 1000 m above mean sea level.
Position feedback is provided through digital servo feedback (HSF), which uses an optical measurement method to create high-resolution incremental counts for the drive controller. With relative position detection, the system achieves a total accuracy window of ± 0.5 angular minutes, which supports tight registration in print, tool, or assembly axes. The motor uses winding code 024, which sets the voltage constant and current ratings expected by MHD-compatible drives. The optical feedback system gives the controller consistent position data during rapid duty cycles and fast reversals.
