Product Description

Drive and motion control has been revolutionized worldwide by the release of products by Bosch Rexroth. The company is the creator of the MDD series of servo motors which can be used to build economic and rapid-response systems. Drives with these motors are used in robotics, machine tools, and handling equipment.

The MDD112D-N-020-N2M-130GB0 is a model of the MDD synchronous servo motors designed and manufactured by Bosch Rexroth. It is a permanent magnet excited motor whose permanent magnets are made from rare earth or iron oxide magnetic materials. As a result, the motor has low inertia and a favorable torque-inertia ratio that makes it suitable for highly dynamic operations. Electronic commutation is one feature of this servo motor that gives it a high cyclic load capacity, ideal for continuous start-stop operations with high repetition rates. The motor can also be used for applications that demand an increased level of precision and synchronism, as seen in grinding machines.

Position detection and speed control in the MDD112D-N-020-N2M-130GB0 is achieved via digital servo feedback with an integrated multiturn encoder. This encoder uses the optical measuring principle to evaluate the absolute indirect position of the motor and has a system accuracy of  ±0.5 angular minutes. The motor’s nominal speed is 2,000 revolutions per minute, and it is a product of Balance Class N according to DIN VDE 0530. Its brushless design and lifetime-lubricated bearings allow it to be operated maintenance-free. A plain output shaft with a shaft sealing ring is also present in the motor to ensure a backlash-free and non-positive transmission of torque. The shaft sealing ring prevents liquids from entering the motor housing through the shaft.
