R911276749 (MHD041A-144-PG0-UN)

Description

The Rexroth Indramat's R911276749 (MHD041A-144-PG0-UN) servo motor, part of the MHD motor series, weighs 2.9kg and has a frame size of 82mm-flange with a 50mm centering diameter. The motor, categorized as size "041" and length category "A", has a continuous standstill torque of 1.35Nm. It possesses a characteristic speed of 7,000rpm, a rated speed of 4,000rpm under a DC link voltage of 540VDC, and employs conventional cooling. Its over-temperature ratings are set at 60k and 100k, with a permissible storage and transport temperature range of -20 to 80 degrees Celsius and a maximum permitted ambient temperature of 40 degrees Celsius. Without the holding brakes or fan unit, this high-efficiency, low-maintenance, high-precision control motor weighs 2.9Kg. The R911276749 (MHD041A-144-PG0-UN) motor utilizes digital servo feedback with an integrated multi-turn absolute encoder and a plain shaft with no holding brake. The output power and feedback connections can rotate 270 degrees, making it ideal for applications requiring high-precision positioning over a long range. Its moment of inertia is 0.88 x 10-4 kgm2, and it has a maximum speed of 7,500rpm. The motor possesses a theoretical maximum torque of 5.6Nm, a winding inductance of 13.5mH, and a peak current of 15.8A.
