Product Description

Bosch Rexroth is a global engineering brand with numerous excellently designed drive and motion control units in its portfolio. The MDD synchronous servo motors are one of its products used to build cost-effective rapid-response automation systems when combined with Indramat digital drive controllers.

The MDD093B-N-040-N2L-110PB0 is one of the synchronous servo motors in Bosch Rexroth’s MDD series. Its motor feedback is digital servo feedback, and it evaluates the motor’s relative indirect position. Since it uses the optical measurement method, this encoder functions with high-level precision and has a system accuracy of ±0.5 angular minutes. With its data memory that stores relevant motor information, the motor’s startup time is reduced, and it can adjust to its drive controller without the risk of damage. Like other MDD servo motors, this model has a brushless design and bearings that stay lubricated throughout their service life. The nominal lifetime of the bearings is 30,000 operating hours.

Heat dissipation during the operation of the MDD093B-N-040-N2L-110PB0 is achieved via natural convection and surface cooling. It also has a thermal sensor in its stator windings to monitor its temperature and prevent damage due to thermal overload. The servo motor’s nominal speed is 4,000 revolutions per minute, and it has a rotor with a moment of inertia of 29 x 10^-4 kgm². This rotor has permanent magnets composed of high-quality materials, giving the motor low inertia and a favorable torque-inertia ratio for high dynamics. Electronic commutation in the motor gives it a high cyclic load capacity so that it supports continuous start-stop operations with high repetition rates. During its operation, the ambient temperature should be maintained between 0^oC and 45^oC.
