Product Description:
The MHD093C-035-PG0-BN is a synchronous servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Designed for closed-loop operation with Rexroth drive controllers, it delivers dynamic torque and velocity control to automated machining centers, pick-and-place gantries, and packaging lines. The motor’s integrated feedback device allows the control system to verify position in real time, so mechanical motion stays aligned with electronic command profiles. This supports accurate speed regulation and repeatable positioning during changing load conditions.
At standstill, the rotor delivers 23.0 Nm of continuous torque for stable holding during milling and indexing. Heat is removed through a liquid-cooling jacket that circulates coolant along the stator, so output is unaffected by enclosure air. The housing carries an IP65 rating that blocks dust and water jets. Centering is handled by a 130 mm pilot on the 140/150 mm square flange, keeping the shaft concentric with the load. Ambient operation is permitted at 0 to 40 °C. Position data comes from an optically read digital servo encoder. Its absolute track resolves more than 4096 revolutions for fine interpolation on multi-axis machines.
Installation is permitted up to 1000 m above mean sea level, so performance is unaffected on mezzanine or elevated conveyor platforms. The windings use F class insulation, and the electromagnetic design follows winding code 035 to match the drive’s rated voltage and current. The plain shaft transmits torque without a keyway, and a shaft seal protects the bearing cavity from coolant splash. This arrangement helps protect internal bearing areas in wet machine environments. Because the motor is supplied without a holding brake, external locking devices must secure vertical loads when power is removed. Power and feedback connectors are routed to side B, and the C-length, size 093 frame can be stored from -20 to +80 °C without damage. System accuracy of ± 0.5 angular minutes supports repeatable contouring in servo-controlled axes.
