Product Description:

The MHD093B-058-PG0-AN belongs to the MHD Synchronous Motors series produced by Bosch Rexroth Indramat. This brushless AC servo motor performs closed-loop speed and position tasks in machine tools, packaging stations, and material-handling axes. Its synchronous design lets the drive regulate torque quickly during rapid starts, stops, and directional changes. An integrated digital servo feedback encoder returns absolute rotor data to the drive controller, enabling tight control loops without additional sensors. In industrial automation cells, the motor converts regulated electrical power into precise mechanical rotation and serves as the primary actuation element for synchronized multi-axis assemblies.

The motor sustains 17.5 Nm of continuous standstill torque, allowing it to hold static loads or accelerate heavy inertias without overheating while energized at zero speed. Its housing carries an IP65 rating that helps protect internal components from dust and low-pressure water jets in areas with coolant spray or airborne debris. A cooling jacket with liquid cooling channels coolant directly around the stator, rapidly removing heat and maintaining stable winding temperatures during high-duty operation. This cooling method reduces reliance on surrounding air movement, which is useful in enclosed machinery. The pilot diameter of 130 mm aligns the flange on the machine frame, and the motor supports positioning accuracy of ±0.5 angular minutes for tight contour control in interpolated moves.

Operation is permitted in ambient temperatures from 0 to 40 °C, and the windings use class F insulation for thermal durability. The unit is supplied without a holding brake, so power-off load retention must be provided by external mechanical locking or drive torque. Position feedback is provided as absolute feedback over >4096 revolutions, allowing the controller to restore shaft orientation after power cycling without a homing move. Additional features include a 140/150 mm flange pattern, a plain shaft with a factory-installed seal, a side-A output connector, and permitted mounting up to 1000 m above mean sea level. The side-A output connector can simplify cable routing when rear access is limited.
