Product Description:

The MHD115B-058-PG1-AN servo motor is manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is intended for high-precision rotary axes in industrial automation where accurate torque delivery and repeatable positioning are required. A digital servo feedback encoder with absolute detection over more than 4096 revolutions continually relays rotor position to the controller, allowing the motor to maintain commanded angles even when load conditions fluctuate.

At the mechanical interface, the unit can deliver a continuous standstill torque of 50.0 Nm, giving a stable margin for holding and low-speed motion tasks. Installation uses a flange that measures 192 mm across, while an integrated centering pilot of 180 mm helps ensure concentric mounting to gearboxes or machine frames. The housing carries an IP65 rating, so dust ingress and direct water jets do not affect operation inside enclosures. Heat is extracted through liquid cooling, keeping the F-class windings below their thermal limit during continuous duty. The motor uses winding code 058 in a B-length housing, and power is routed to side A through an output connector while the plain shaft is sealed to prevent coolant or oil entry.

A built-in holding brake supplies 70.0 Nm of static torque, preventing axis drift when power is removed and complementing the motor's system accuracy of ±0.5 angular minutes. The rated ambient temperature range is 0 to 40 °C, while storage is permissible between -20 °C and 80 °C, so the motor can withstand common warehouse and shop-floor environments. Installation is permitted up to 1000 m above mean sea level, allowing use in most production facilities without derating. A shaft seal is present, the measurement system is optical, and insulation class F materials support long-term reliability under cyclical thermal loading.
