Product Description:
The MHD093C-035-PG1-BN is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It fits into multi-axis gantries, transfer lines, and general automation where compact torque delivery and high positioning accuracy are needed. Coupled to a suitable drive controller, the motor transforms regulated three-phase power into rotary motion, forming the actuator side of a closed-loop system used for precise velocity and position tasks in industrial equipment. Its synchronous design supports quick response to command changes during indexing, positioning, and speed-regulated motion. The compact housing also suits machine layouts where motor space is limited but stable output is still required.
At standstill, the rotor can sustain a continuous torque of 23.0 Nm, providing ample margin for static loads without excessive thermal rise. The housing carries an IP65 rating that blocks dust and water jets, while liquid cooling channels in the stator remove heat so full current can be maintained inside sealed cabinets. Class F insulation supports winding temperatures up to 155 °C. Mechanical alignment is assisted by the 130 mm centering register and a flange pattern of 140/150 mm, which helps the motor seat accurately against the machine interface. Power exits toward side B through an output connector, keeping cables clear of couplings. Optical digital servo feedback reports rotor position to the drive. The motor uses frame size 093 with length code C, and the electrical data follow winding code 035.
For secure holding during power-off conditions, the built-in brake supplies 22.0 Nm of static torque. The feedback system uses absolute feedback with more than 4,096 revolutions, enabling system accuracy of ± 0.5 angular minutes and eliminating homing cycles after startup. The motor operates in ambient temperatures from 0 to 40 °C, may be stored from −20 to +80 °C, and can be mounted up to 1,000 m above mean sea level without derating. A plain shaft with an integral seal keeps lubricant in and contaminants out. The feedback system continues to provide position data throughout the stated operating range.
