Product Description:
The MHD115B-024-PP1-AA is a servo motor built by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for closed-loop positioning and speed regulation in automated machinery, the unit converts commanded electrical energy from a drive into precise mechanical motion through its permanent-magnet rotor and integral feedback. Its integrated feedback allows the connected drive to monitor rotor position continuously during acceleration, deceleration, and steady-speed operation. By delivering controlled torque to axes such as gantries, presses, and packaging stations, it forms the actuation element in many CNC and material-handling cells.
The motor uses winding code 024 with motor size 115 and length B, a configuration that produces a continuous standstill torque of 50.0 Nm, while heat is removed by natural convection through the ribbed housing. Mounting is facilitated by a centering diameter of 180 mm and a square flange of 192 mm, allowing rigid coupling to standardized machine frames. The keyed shaft transmits torque and is protected by a shaft seal that helps prevent oil or dust ingress, and the enclosure is rated IP65. Electrical power reaches the stator windings through a connector on side A, and insulation class F materials permit winding temperatures up to 155 °C. Position feedback is handled by a digital servo encoder that uses an optical measurement method and provides absolute information beyond 4096 revolutions, enabling tight synchronous control. The feedback signals leave the motor through the same connector group.
A holding brake is fitted and can secure the axis with a torque of 70.0 Nm whenever power is removed. The feedback system delivers a system accuracy of ±0.5 angular minutes, keeping positional deviation low for contouring or indexing tasks. Reliable operation is specified at ambient temperatures from 0 to 40 °C and at installation elevations up to 1000 m above mean sea level, while storage temperatures from −20 to +80 °C permit safe transport or long-term storage.
