Product Description:
The MHD115C-058-PG1-AN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. As a motor for digitally controlled axes, it converts drive current into rotational motion for positioning tasks on presses, packaging lines, and gantry modules. The 115 frame size and C-length stator give the motor a compact profile for applications that need substantial torque without requiring a much larger housing. Integrated feedback and braking functions support closed-loop motion control and stable axis behavior during start, stop, and hold periods.
Its continuous torque at standstill reaches 70.0 Nm, allowing the axis to hold heavy loads without overheating while the rotor remains stationary. Thermal energy is removed through liquid cooling, which helps keep winding temperatures stable during sustained duty and repeated load changes. Position information is supplied by digital servo feedback, and the encoder provides absolute (>4096 revolutions) measurement so the controller can recover rotor position after power is restored. Winding code 058 identifies the electrical setup used for this model, including the selected resistance and inductance values matched to drive operation. This combination supports repeatable motion and smooth response in applications that cycle frequently between holding and movement.
The motor includes a holding brake that can lock the rotor during idle periods or controlled stops. Power conductors leave the stator through an output connector on side A, which keeps cable routing consistent relative to the cooling connections. The motor uses a plain shaft for direct coupling to gearboxes or pulleys, and the shaft seal helps limit liquid ingress along the journal. This layout helps when the motor is installed in compact machinery where cable direction and shaft sealing affect the surrounding hardware.
