Product Description

Automation businesses seeking to enhance their productivity can rely on Bosch Rexroth for the most efficient drive and motion control products. The company’s MDD motors are compact synchronous servo motors with varying torques, speeds, and sizes.

The MDD071A-N-040-N2S-095GB1 is an MDD motor with a high power density. Hence, it can accommodate highly dynamic applications such as roller feeds for punching, pressing, and nibbling machines, and tool-changing devices. Like others in this series, it displays impressive operational reliability since it supports maintenance-free operation. Its brushless design and lifetime-lubricated bearings ensure this, as well as its temperature monitoring system. A thermal sensor is integrated into its windings to monitor its temperature and prevent damage due to overheating. The heat in the stator windings is also well-regulated by dissipation to the outside walls of the motor housing. Overall, the motor is cooled by natural convection and surface cooling; hence, it supports extreme loads.

Another protective feature of the MDD071A-N-040-N2S-095GB1 is the design of its power and feedback cables to meet the standard of the IP 65 protection category. Its housing also corresponds with this protection category as it is touch-proof, dustproof, and safe from multidirectional water jets. Digital servo feedback is the feedback type of the MDD model, and it can operate independently of separate incremental encoders. It evaluates the motor’s relative indirect position using the optical measuring method, transferring the data obtained to the intelligent digital drive. This encoder type also has a data storage feature, where relevant motor parameters are stored to reduce the start-up time. The nominal speed of the MDD motor is 4,000 revolutions per minute, and it generates a theoretical maximum torque of 6.9A.
