The R911278591 (MDD093C-L-030-N2L-110GA2), part of the MDD product group, is a high-performance servo motor by Bosch Rexroth that offers seamless integration with drive controllers for efficient automation systems. This motor is known for its high dynamics and overload capabilities, favorable power to weight ratio, high cyclic load capacity, compact size, and high synchronous operations. Unique to the MDD series, this motor includes a feedback system that monitors the rotor’s position and speed. Features include a 22-Nm blocking brake with precise clamping and release delays, and a nominal speed of 3000 revolutions per minute. It has a continuous torque of 28 Nm and a continuous current of 46.2 Amperes at standstill, with a theoretical maximum torque of 60.6 Nm and a peak current of 145 Amperes. This 22 kg motor also includes a plain output shaft and is easy to install due to the defined load assimilation at its shaft and the convenient flange design.
