Product Description:
The MHD115B-035-NP1-BA is a servo motor manufactured by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. It is built for industrial automation axes where closed-loop speed and position control are required, translating electrical drive commands into controlled rotary motion for packaging lines, machine tools, and material-handling equipment. Its synchronous design allows the paired drive to regulate torque, speed, and position with stable response during repeated motion cycles. This makes it suitable for coordinated axes that require accurate starts, stops, and steady speed regulation under changing loads.
At standstill the motor can supply a continuous torque of 50.0 Nm, and its integrated brake can hold up to 70.0 Nm when power is removed. Position feedback is generated by a digital servo feedback (HSF) encoder that uses a relative measurement method and optical scanning for repeatable axis control. Normal operation is permitted between 0 to 40 °C ambient, and the housing uses natural convection cooling to remove heat from the stator. Class F insulation withstands the internal temperatures associated with continuous duty, and the enclosure is sealed to IP65 with a shaft seal at the output end to block dust and water. The motor can operate up to 1000 m above sea level, and the power leads exit on side B through an output connector to keep cable routing orderly in multi-axis cabinets.
The centering register has a diameter of 180 mm, and the mounting flange spans 192 mm, so the motor aligns accurately with gearboxes or direct-drive loads. A keyed shaft transmits torque without slip, and winding code 035 matches the electrical characteristics used by compatible MHD drive controllers. Motor size 115 with length code B indicates the overall frame, while the connection layout keeps terminals clear of adjacent equipment. Static accuracy is limited to ±0.5 angular minutes, supporting fine contouring tasks. The larger flange interface also helps maintain concentric mounting where coupling alignment is important to smooth running. When the machine is idle, the unit may be stored between -20 and +80 °C.
