Product Description:

The MHD115B-058-NP1-AA is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is intended for industrial automation tasks that require closed-loop position and velocity control, translating drive commands into repeatable mechanical output for machine tools, material-handling axes, and packaging lines. The motor supports precise motion in applications that need controlled acceleration, steady running speed, and accurate stopping. This makes it suitable for coordinated axes where repeatability matters during rapid start-stop cycles as well as continuous production movement.

The motor produces a continuous stall torque of 50.0 Nm, and its integrated brake provides 70.0 Nm of holding torque to secure the load when power is removed. This holding capacity helps keep a stopped axis in place between machine cycles. The motor is sealed to IP65, and heat is removed by natural convection, so no external airflow is required for standard operation. Position feedback is supplied by digital servo feedback (HSF) using an optical measuring method with relative position detection, allowing the connected drive to monitor rotor movement accurately. Operation is supported at ambient temperatures from 0 °C to 40 °C and at installation heights up to 1000 m above mean sea level, while the keyed shaft and side-A output connector support straightforward machine integration.

The motor has a centering diameter of 180 mm and a flange size of 192 mm, which allow accurate alignment with standard gearbox faces or mounting plates. These mounting dimensions also support stable attachment when the motor is coupled to rigid mechanical assemblies. Thermal endurance is supported by Class F insulation, which allows winding temperatures up to 155 °C. Under encoder feedback, the system can maintain positional deviation within ± 0.5 angular minutes for precise axis control. The motor uses winding code 058 in a size 115, B-length frame, and its storage temperature range of -20 °C to +80 °C helps protect materials during shipment or downtime. The shaft seal helps limit lubricant leakage when the keyed output shaft is connected to surrounding equipment.
