Product Description:

Bosch Rexroth Indramat builds the MHD093A-035-NG0-AA in the MHD Synchronous Motors series for axis drives that call for continuous torque delivery and precise position feedback. The unit is a servo motor intended to convert electrical energy into controlled rotary motion in automated machinery, packaging stations, and material-handling systems. This operating role suits positioning axes that must accelerate, decelerate, and hold commanded positions with repeatable response during normal machine cycles. Its size code 093 and length code A place it near the lower end of the 093 frame family, giving the motor a compact footprint when cabinet space or mounting depth is constrained.

At standstill, the rotor can apply 12.0 Nm of continuous torque, which allows the axis to resist static load without additional gearing. A shaft centering diameter of 130 mm matches the standard machine flange and keeps the motor concentric with the driven element. The flange has a 140 / 150 mm interface, so the mounting holes fit common IEC layouts. The motor is sealed to IP65, which helps keep out dust and low-pressure water jets. Position feedback is provided by digital servo feedback (HSF), which transmits high-speed incremental data to the drive controller for closed-loop regulation. The encoder works with the drive so speed and position corrections can be applied continuously during motion.

Thermal losses are removed through natural convection, so no external blower or liquid circuit is required when the ambient temperature stays within 0 to 40 °C. This cooling method keeps the housing simple and avoids the need for separate airflow hardware around the motor. Class F insulation supports elevated winding temperature during cyclic loading. The motor preserves positional precision within ± 0.5 angular minutes, and the optical measurement system reports rotor displacement as a relative value each time the drive powers up. A plain shaft with an installed seal limits lubricant migration, and the power leads exit toward side A through an output connector that simplifies cable routing at installation heights up to 1000 m above sea level.
