Product Description:

The MHD115B-058-PG0-BA is a servo motor produced by Bosch Rexroth Indramat in the MHD Synchronous Motors series. It interfaces with a drive controller to convert electrical commands into controlled rotary motion for indexing tables, gantry axes, and other precision automation tasks. Its synchronous design supports dynamic response during continuous duty, where accurate speed control and repeatable positioning are required throughout the operating cycle.

At standstill, the motor delivers 50.0 Nm of continuous torque, allowing heavy loads to be held without external gearing. Its housing is sealed to IP65, which helps keep dust and water jets away from internal components in industrial settings. A centering pilot of 180 mm aligns the flange concentrically with the driven machine and supports accurate mechanical mounting. Heat is removed through natural convection, so no fan is required. Rated performance is maintained between 0 to 40 °C, which matches common shop-floor conditions. Position feedback comes from a digital servo encoder that uses an optical measurement method to achieve ± 0.5 angular minutes of system accuracy, and the absolute feedback covers more than 4096 revolutions. Power reaches the stator through an output connector on side B, and a plain shaft with a shaft seal transmits torque to the load.

The rectangular mounting flange measures 192 mm, and the motor corresponds to size 115 with length code B for a compact overall envelope. For storage, it tolerates temperatures from -20 to +80 °C, allowing the unit to remain protected during transport and inactive periods before installation. Windings built to insulation class F withstand the thermal stress associated with cyclic servo duty. Winding code 058 identifies the electrical characteristics used by compatible MHD drives. The motor is supplied without a holding brake, so static locking must be provided externally when the application requires it.
