Product Description:

The MHD093C-035-NG1-BN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Within an automation cell, this motor couples to a drive controller to position machine axes with high repeatability, supplying regulated torque for material processing, palletizing, or assembly functions where rapid directional changes are required. Its synchronous design supports smooth motion control during repeated start-stop cycles.

Mechanical capability begins with a continuous standstill torque of 23.0 Nm, which lets the shaft hold static loads without excessive heating. A housing rated at IP65 blocks dust ingress and low-pressure water jets, so the unit can be mounted near coolant spray zones. Thermal energy is removed through an internal jacket that supports liquid cooling, keeping winding temperature below the Class F limit during sustained duty cycles. Rotor position is monitored by a digital servo feedback (HSF) encoder that uses an optical measurement method to transmit high-resolution angle data to the drive. In conjunction with the drive's interpolation, the overall system maintains a positioning accuracy of ± 0.5 angular minutes, which is suitable for fine contouring tasks.

The motor operates at ambient temperatures between 0 to 40 °C; outside this range, derating or external conditioning is required. A built-in holding brake supplies 22.0 Nm of static torque to secure vertical or suspended loads when power is removed. Installation is simplified by a centering pilot of 130 mm and a flange circle of 140/150 mm that align the plain shaft to gearboxes or belt pulleys. Power cabling exits on side B through an output connector, and a shaft seal is installed to limit oil migration into the stator cavity. For long-term storage, the assembly tolerates temperatures from -20 to +80 °C, provided the liquid circuit is drained and the encoder electronics remain dry.
