Product Description:

The MHD093C-058-PP0-BA is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is intended to supply closed-loop rotary motion for positioning axes, gantries, and material-handling modules where rapid acceleration and high repeatability are required in industrial automation cells. Its synchronous design allows the paired drive to regulate torque and speed precisely during repeated indexing and positioning moves.

At standstill, the motor can deliver 23.0 Nm of continuous torque, which suits medium-inertia loads that need steady holding force without excessive heating. Mechanical alignment is supported by a centering diameter of 130 mm, while the flange follows a dual pattern of 140 / 150 mm so the frame fits standard mounting plates. The motor has an IP65 enclosure, and heat leaves the stator through natural convection instead of forced airflow. The unit can operate in ambient temperatures from 0 to 40 °C, matching most machine-room climates, and its insulation system is Class F to tolerate winding temperatures up to 155 °C. The lack of an internal holding brake and power leads routed to side B through an output connector complete the mechanical interface. Up to 1000 m above mean sea level, the torque rating remains unchanged.

Feedback is handled by a digital servo encoder that uses optical scanning to capture rotor position with a system precision of ± 0.5 angular minutes. Position data is stored as an absolute value for more than 4096 revolutions, so the controller retains exact shaft angle after power cycling. A keyed shaft transmits torque without slip, and a shaft seal is fitted to keep coolant and lubricants out of the bearing chamber. The motor body uses size 093, length code C, and winding code 058 to match drive parameters such as rated current and inductance. When the machine is idle, the device may be stored between −20 °C and +80 °C without degrading the magnets or insulation.
