Product Description:

The MHD112D-027-PG3-AN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Designed to convert commanded current into controlled rotary motion, it is used as a drive element in automated material handling, packaging, and machining stations where repeatable speed and positioning are required. The motor interfaces with Indramat drive controllers to form a closed-loop axis that supports precise, high-cycle industrial processes.

At standstill, the motor can deliver a continuous torque of 48.0 Nm, which provides steady output for static cutting or tensioning operations without overheating. Heat is removed through liquid cooling, so full torque can be maintained in densely packed cabinets. The housing carries an IP65 protection rating, keeping dust and water jets away from the internal windings, and the insulation class is F. Mechanical alignment is simplified by a centering diameter of 130 mm, and the motor uses a plain shaft with a shaft seal. Position feedback is generated optically by a digital servo encoder that provides absolute data over more than 4096 revolutions. Storage is permitted between -20 °C and +80 °C, and installation up to 1000 m above mean sea level is allowed.

The integrated holding brake supplies up to 70.0 Nm of static torque, allowing vertical axes to stay locked when power is removed. During motion, the optical feedback chain maintains a system accuracy of ± 0.5 angular minutes, so the drive can execute fine positioning within the approved operating ambient range of 0 to 40 °C. The square mounting flange measures 192 mm, providing a rigid interface for gearheads or direct couplings while leaving clearance for the coolant jacket. The motor uses winding code 027 in size 112 with length D, and its power leads exit on side A through an output connector.
