Product Description:
The MHD115B-058-PG0-BN is a three-phase servo motor manufactured by Bosch Rexroth Indramat and supplied within the MHD Synchronous Motors series. Designed for closed-loop industrial automation, the unit converts drive commands into precise rotary motion for positioning tasks on machine tools, material-handling axes, and packaging stations. It is a synchronous servo motor intended for applications that require accurate speed regulation and repeatable axis positioning. Digital servo feedback with an integrated encoder provides continuous speed and position information to the drive controller during operation.
At standstill, it can supply 50.0 Nm of continuous torque, delivered by the 115 frame with winding code 058. The centering pilot measures 180 mm in diameter and mates with a 192 mm square flange, so the motor can be aligned accurately at the mounting face. Heat is removed through liquid cooling, which allows sustained output while helping the housing stay within insulation class F limits. The motor is sealed to IP65, and the shaft uses a seal at the output end. Power is routed through a connector on side B, and the unit is supplied without a holding brake.
The feedback system uses an optical measuring method with Absolute (>4096 revolutions) feedback and delivers a system accuracy of ±0.5 angular minutes. Storage temperatures range from -20 to +80 °C, and the permitted operating ambient temperature is 0 to 40 °C. Operation is allowed up to 1,000 m above sea level. The integrated encoder sends speed and position data to the drive controller in real time, supporting closed-loop correction during acceleration, deceleration, and holding intervals. This arrangement lets the drive monitor rotor position continuously without separate external feedback hardware. The optical feedback system also supports stable motion control during low-speed operation and repeated positioning cycles.
