Product Description:
The MHD095B-058-NP0-AN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. Intended for CNC axes, material-handling stations, and other automated equipment, the motor supplies controlled torque and position feedback so the drive controller can regulate motion with high repeatability. Its integrated optical position sensor and electronic commutation let the unit operate as a direct-coupled actuator, eliminating belts or gearboxes in many installations and improving response times under dynamic load changes.
The mechanical envelope follows the 095 frame and B length codes, and it bolts to a 140/150 mm square flange that is centered by a 130 mm pilot. Protection reaches IP65, so dust ingress and low-pressure water jets do not affect the windings or the integral shaft seal. A keyed shaft transfers torque to couplings, while the liquid-filled jacket provides liquid cooling around the stator to remove heat during continuous duty. Speed and position are monitored by digital servo feedback (HSF), which is created optically and referenced as relative position. Power conductors exit on side A through an output connector, and winding code 058 aligns the electrical parameters with compatible Indramat drive families. The motor is supplied without a holding brake, which reduces overall mass.
At standstill, the motor can generate 17.5 Nm of continuous torque, making it suitable for medium-inertia loads that demand steady holding force. Class F insulation allows the stator temperature to rise without premature aging, and operation is specified for ambient air temperatures of 0 to 40 °C. Accuracy of the feedback chain is maintained within ± 0.5 angular minutes, supporting fine positioning on milling spindles and gantry drives. The unit can be installed up to 1000 m above mean sea level without derating, and it may be stored from −20 to +80 °C when the machine is idle. A relative measurement scheme is used, so an external homing routine is needed after power-up.
