Product Description

Bosch Rexroth designed the MDD servo motors to suit different kinds of factory automation applications. They are permanent magnet-excited motors that form economic rapid-response automation systems with Indramat drive controllers. Drives with the motors are used in machine tools, robotics, and handling equipment.

The MDD112B-N-030-N2M-130GA2 is a model of the MDD synchronous motors designed and manufactured by Bosch Rexroth. With its brushless design and lifetime-lubricated bearings, it is built for maintenance-free operation. The bearings have a nominal service lifetime of 30,000 hours and are designed to support high radial loads. As a result, they allow belt pulleys and pinions to be directly attached to the motor shaft. There is a thermal sensor in the windings of this MDD model, and it serves as a temperature monitoring system to prevent thermal overload. The motor cools using surface cooling and natural convection. Its centering diameter is 130mm, and its theoretical maximum torque is 64.5Nm.

Another feature of the MDD112B-N-030-N2M-130GA2 is electronic commutation. It gives the motor a high cyclic load capacity so that it can be used for continuous start-stop operations with high repetition rates. As a product of Balance Class N according to DIN VDE 0530, the motor is ideal for normal applications. Its housing is completely sealed and will not admit any solid extrinsic objects or sprays from water jets. Hence, it has an IP 65 protection rating according to EN 60529 and can be used in harsh environmental conditions with minimal risks of damage. The encoder here is digital servo feedback with an integrated multiturn encoder. It has a system accuracy of ±0.5 angular minutes and detects the motor’s absolute indirect position using the optical method.
