Product Description:
The MHD090B-047-NG1-UN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It forms the rotary actuation stage in closed-loop industrial axes, converting drive current from Rexroth controllers into mechanical rotation with high position repeatability. The motor incorporates relative optical feedback to inform the drive of rotor position, making it suitable for packaging lines, machining centers, and material-handling modules that require coordinated motion within multi-axis automation cells.
Its continuous stall capability is rated at 12.0 Nm, allowing the shaft to hold steady loads without overheating during static positioning cycles. The housing is sealed to IP65, so dust and sprayed water are kept away from the windings and the integrated digital feedback sensor. Thermal energy is removed by liquid cooling, with coolant circulating around the stator to sustain full torque at elevated ambient temperatures. Mechanical interface dimensions include a 110 mm centering diameter that aligns the flange to gearboxes and a square flange of 140 mm that matches IEC mounting patterns. Insulation class F permits winding temperatures up to 155 °C during intermittent overloads.
In dynamic duty profiles, the integrated holding brake supplies 11.0 Nm of static torque, maintaining axis position when power is removed during tool changes or safety stops. The motor operates reliably from 0 to 40 °C, and it can be stored from −20 °C to 80 °C without affecting magnet strength. Positional precision is supported by a feedback system with an accuracy of ±0.5 angular minutes. Cable management is simplified because the power connector can be rotated through 270°, so the same unit fits cabinets with different entry directions. Additional features include an oil-resistant shaft seal, a plain output shaft for backlash-free couplings, and permissible installation heights up to 1000 m above mean sea level.
