Product Description:

The MHD112C-035-NG0-LN is manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. The motor serves as a compact rotational actuator for CNC axes, presses, and automated handling systems that require closed-loop speed and position control. Designed to work with digital drives, it converts electrical energy into mechanical rotation through three-phase windings while transmitting actual position back to the controller. This arrangement lets the control system compare commanded and actual motion continuously, which helps maintain stable axis response during indexing and contouring.

At standstill, the motor can deliver a continuous torque of 38.0 Nm, which allows the axis to resist load without an auxiliary brake in many applications. Heat generated by copper losses is removed through liquid cooling, so full torque is available with low temperature rise during prolonged duty cycles. The housing has an IP65 rating, which helps keep dust and low-pressure water jets away from internal parts when the motor is mounted on the machine frame. The mechanical interface uses a 192 mm square flange, and alignment to the coupling face is maintained by a 130 mm centering diameter. These dimensions match the 112 frame size and support direct installation on compatible machine mounting surfaces.

The windings use insulation class F, which supports continuous operation at elevated internal temperatures without dielectric breakdown. Rotor position is sensed by an optical encoder that provides digital servo feedback (HSF), and this feedback arrangement supports a positioning accuracy of ± 0.5 angular minutes for repeatable machining results. For installation, the motor uses a plain shaft with a shaft seal, and the power connector is routed to the left. It comes without a holding brake, which reduces mass for high-response axes. Rated conditions allow operation from 0 to 40 °C and storage from -20 to +80 °C. Altitudes up to 1000 m above sea level are acceptable, and the motor uses winding code 035, motor length C, and relative position detection.
