Product Description:

The MHD115B-058-PG1-BN is a servo motor produced by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. Designed for high-precision axis control, it integrates into CNC machines, robotics, and printing lines where exact velocity and position regulation are required. The motor uses winding code 058 and a digital feedback system so the connected drive can command rapid, repeatable motion while maintaining the accuracy needed in industrial automation. It is suited to axes that must accelerate, dwell, and reverse direction while keeping commanded position error low.

At standstill, the rotor can deliver a continuous torque of 50.0 Nm, allowing heavy loads to be held without overheating. The enclosure carries an IP65 rating, so dust ingress is prevented and water jets will not compromise operation. Heat is extracted through liquid cooling, which supports full-load running in confined cabinets, and the unit is specified for ambient operation from 0 to 40 °C, matching common factory floor climates. Position data are gathered by an integrated digital servo encoder that measures optically and reports absolute values for more than 4096 revolutions, achieving a system accuracy of ±0.5 angular minutes. A plain shaft transmits torque directly, and power is fed through an output connector mounted on side B of the housing.

A holding brake rated at 70.0 Nm secures vertical axes during shutdown, and a shaft seal helps keep coolant or lubricants away from the bearing zone. The centering pilot measures 180 mm, while the square flange spans 192 mm, enabling rigid attachment to machine frames or gearboxes and helping maintain alignment at the mounting face. Storage is permissible from -20 to +80 °C, and the insulation system uses class F materials for the expected winding temperature range. Motor size 115, length code B, and a maximum installation height of 1000 m above mean sea level apply to this configuration.
