Product Description:

The MDD090A-N-020-N2M-130GL0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts electrical power from the drive into regulated mechanical motion for positioning tasks in industrial automation. Its 090 stator diameter and A length code help it fit compact multi-axis assemblies, while the standard housing and factory balancing support stable operation in space-limited machine layouts. The synchronous design also supports accurate response during repeated starts, stops, and speed changes.

At standstill, the motor can deliver 3.7 Nm of continuous torque, providing predictable holding force for static loads without exceeding thermal limits. Under rated excitation, it reaches a nominal speed of 2000 rpm, pairing moderate torque with steady rotational velocity for conveyor or indexing duties. The flange carries a centering pilot of 130 mm, which helps maintain concentric alignment with gearheads or machine frames. Electrical power and feedback conductors exit on the left through a sealed connector that simplifies cable removal during maintenance. Rotor position data come from an integrated multi-turn absolute encoder and are transmitted as digital servo feedback (DSF), giving the drive high-resolution information for closed-loop control. Standard dynamic balancing helps limit vibration during acceleration and steady operation.

The motor uses a simple mechanical layout suited to direct coupling in automated equipment. It is supplied without a blocking brake, so vertical or suspended loads require external holding force when the system is shut down. The output uses a plain shaft in a standard single-ended configuration, with no secondary extension on side B, which supports direct connection to pinions or flexible couplings. The unit is delivered with a shaft seal, helping keep dust and incidental fluid contact away from the internal bearings in enclosed installations.
