R911252978
The R911252978 (MDD112D-N-020-N2L-130PA1) is a synchronous servo motor produced by industry-leading Bosch Rexroth. As a part of the brand's MDD range, this motor features permanent magnet excitement and electronic commutation. Its diverse application and outstanding performance in high speed cutting makes it an ideal choice for various industries including printing, packaging, textiles, robotics and more. Its in-built digital servo feedback provides high precision by indirectly recording the motor's position and storing it in the digital drive.
Specifically designed for applications requiring high precision and extreme synchronism, like grinding machines, the R911252978 (MDD112D-N-020-N2L-130PA1) is equipped with a 14.0Nm block brake for backlash-free hold when de-energized. Additionally, it possesses a shaft with a keyway, per DIN 6885-1 standards, for a close-fitting shaft-hub connection. The motor's housing design adheres to DIN 40050 standard, allowing for natural convection cooling and surface cooling. The presence of a temperature sensor within the windings aids in overload prevention by monitoring the motor's temperature. Furthermore, the motor's long-lasting brushless design and its high cyclic load capacity make it suitable for start-stop operations with high repetition rates.
