Product Description:

The MHD112B-035-PG2-BN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It delivers controlled rotary motion to automated axes in machining centers, packaging machines, and material-handling stations where repeatable speed and position control are required. Its 112-frame housing with length code B contains a digital servo feedback encoder that is scanned optically to report absolute rotor position to the drive. The motor also uses a plain shaft with an internal shaft seal, which supports direct coupling to gears, pulleys, or belt drives while helping keep lubricant inside the bearing area.

Continuous standstill torque reaches 28.0 Nm, allowing the motor to hold load at zero speed when the drive supplies current. Excess heat is removed by liquid cooling rather than ambient air, which supports thermal control in compact machine spaces. Mounting aligns on a centering diameter of 130 mm, while a 192 mm square flange provides four through-holes for rigid attachment. The housing carries an IP65 rating to resist dust and low-pressure water spray. The power connection is located on side B, and winding code 035 matches the electrical characteristics expected by compatible Indramat inverters. Performance data apply at installation heights up to 1000 m above mean sea level.

For static holding tasks, the built-in brake supplies 32.0 Nm of holding torque when power is removed, which helps prevent unintended shaft movement on stopped axes. The windings use class F insulation and are intended for ambient conditions from 0 to 40 °C. Closed-loop positioning accuracy is ± 0.5 angular minutes, and the encoder provides absolute multi-turn feedback for more than 4096 revolutions. Storage from -20 to +80 °C is permitted when the motor is not operating. The plain shaft and seated shaft seal keep the output end simple for coupling components that do not require a keyed interface.
