Product Description

Bosch Rexroth’s MDD servo motors are powerful units that ensure high contouring accuracies at high feedrates. They come in a range of sizes, speeds, and torques and form rapid-response automation systems with intelligent digital drive controllers from Indramat.

The MDD093C-N-020-N2M-110GB2 is a model of the MDD synchronous servo motors featuring digital servo feedback with an integrated multiturn absolute encoder. This encoder’s system accuracy is ±0.5 angular minutes, and it evaluates the motor’s absolute indirect position. It uses the optical measurement method, guaranteeing high-level precision in its function. The encoder’s data memory stores the motor type name and control loop parameters so that its startup time is reduced and it can adapt safely to the drive controller. Given its sealed housing, it can function under adverse environmental conditions without the risk of damage. This housing’s Ingress Protection rating is IP 65 according to DIN 40 050, indicating that it is touch-proof, dustproof, and impervious to water jet sprays.

Irreversible damage due to thermal overload is averted in the MDD093C-N-020-N2M-110GB2 with the aid of a thermal sensor built into its stator windings. Heat is also efficiently eliminated from its stator, giving it a high overload capability. It has electronic commutation, a feature that gives it a high cyclic load capacity for continuous start-stop operations with high repetition rates. Its bearings have a nominal service lifetime of 30,000 operating hours and remain lubricated throughout their service life. Pinions and belt pulleys can be directly attached to its shaft because its design allows the application of high radial loads. The shaft in the MDD motor is the plain type with a shaft sealing ring, providing a non-positive zero-backlash shaft-hub connection.
