The Bosch Rexroth R911262509 (MDD090B-N-040-N2M-110PA2) is a digital AC motor featuring an encoder with an optical system for measurement. With a total of 340m length, it operates at a top speed determined by the DC bus voltage at the power supply source. The motor follows DIN 42955 specifications for shaft concentricity and coaxiality, but has a limited bearing lifespan under high radial loads. The device has a phase current of 13.7A with natural convection and uses power and feedback cables, which are each a maximum of 75m long. The connectors for these cables must be purchased separately. The motor also ensures maintenance-free operation and displays reduced performance at temperatures between 45°C and 55°C. Suitable for applications requiring high synchronism, it employs electronic commutation and offers a Indramat USA warranty valid for one year. Transport and shipping should keep the motor dry, and it should not be lifted by the blower.
