Product Description

When combined with Bosch Rexroth's digital AC servo motors, the Indramat drive controllers enable the development of fast-response automation systems. They also combine to form drives for machinery, robots, material-handling tools, and industrial transport networks. The MDD line of servo motors is maintenance-free motors that have a brushless design as well as bearings that are lubricated for life.

One of the MDD servo motors produced by Bosch Rexroth is known as the MDD112B-N-020-N2L-130PB1. The frame size of this motor is 112, and the frame length is B. It is equipped with electronic commutation which provides it with a large cyclic load capacity, making it suitable for high-repetition applications involving many starts and stops. The installation of this motor is made easier due to the direct attachment of pinions and belt pulleys to its shaft. The design of this motor allows for the application of high radial loads, which makes this attachment method possible. Additionally, it can be installed in any position the user desires, and it makes use of pre-made cables, which significantly cut down on the amount of work required for installation.

The nominal speed rating of the MDD112B-N-020-N2L-130PB1 is 2,000 per minute. It has a theoretical maximum torque of 65.1 Nm and a peak current of 82.6 A. Its motor feedback system is digital servo feedback with a system accuracy of ±0.5 angular minutes. This encoder calculates the motor's indirect relative position and records it in the digital control unit. This MDD motor model includes a temperature monitoring system that prevents burnout due to overheating. Also, it can be used in harsh environments thanks to its Ingress Protection rating of IP 65 and its fully sealed design.
