R911257812
The R911257812 (MDD093A-N-020-N2L-110GA0) is an industrially oriented servo motor engineered by Bosch Rexroth Indramat, one of the well-known designers in industrial drive control systems. This servo motor is purpose-designed for diverse drive control functions and is deemed compatible with a broad spectrum of factory machinery such as nibbling and woodworking machines, punching machines, and roller feeds for presses. It has been manufactured to support precise and accurate operations in assembly lines and streamline mass production. Built within this motor is an optical measurement system for absolute measurements and a digital servo feedback system, eliminating the need for separate incremental encoders and substantially enhancing position control capabilities. The motor is versatile and functions well in various environmental conditions.
R911257812 (MDD093A-N-020-N2L-110GA0) thrives in a temperature range of 0 °C to 45 °C. It features class 155 insulation qualities safeguarding its sensitive components from short circuits. Weighing only 13 kg, it can generate maximum torque of 28.6 Nm and continuous torque of 9.2 Nm. With a peak current of 45.8 A, it has an exceptionally low rotor inertia providing easy accelerations and decelerations, thus enabling high-speed start-stop applications. With an added benefit of a thermal time constant of 50 minutes, electronic commutation augments the peak torque potential at all speeds.
