Description

The Bosch Rexroth R911256171 (MDD090C-N-020-N2L-110PB2) from the MDD series of servo motors is particularly suitable for applications requiring high precision and synchronicity, such as in grinding machines. Engineered for a maximum current of 72.9A and a nominal speed of 2,000 RPM, the motor is designed with weather-resistant black prime varnish, promising robustness against environmental factors. The motor boasts of cooling mechanisms and is certified for protection against external objects and multi-directional water jets with a IP 65 rating. It incorporates digital servo feedback and an encoder with system accuracy of ±0.5 angular minutes. A built-in data memory hastens the boot up process. The motor's rotor employs permanent magnet materials, ensuring high dynamics through its inertia and optimal torque-inertia ratio. It features a keyway shaft for form-fitting shaft-hub connection and a shaft sealing ring, with the blocking brake delivering a torque of 11.0Nm.
