Product Description:

Bosch Rexroth Indramat produces the MDD093B-N-030-N5M-130PB1 Synchronous servo motor. It is a member of the MDD series, which is made for applications requiring precise control of motion. The motor is capable of multiturn absolute position encoding and runs on digital servo feedback. With its precision torque response and speed regulation capabilities, the MDD093B is ideal for use in situations involving continuous loads.

At a standstill, the MDD093B-N-030-N5M-130PB1 servo motor can provide a continuous torque of 14.5 Nm and a nominal speed of 3000 rpm. The constant torque rises to 20.0 Nm as the surface cools. Up to 45.1 Nm of torque is possible in theory. The MDD servo motor is capable of brief acceleration bursts due to its peak current of 108.2 A. The stable rotation and smooth performance are supported by the rotor's moment of inertia, which is 29 × 10⁻⁴ kgm². Shaft holding is maintained during standstill by use of an integrated 11 Nm blocking brake, which is part of the 093 motor. Because of its strong construction, the motor weighs 16.5 kg. When used in servo assemblies, the 130 mm centering diameter guarantees an ideal fit. Industrial automation motion control systems are compatible with the MDD093B servo motor.

An integrated blocking brake with 11 Nm torque is available for static load holding on this servo motor. Applying surface cooling causes the continuous current, which is 24.1 A at rest, to increase to 33.2 A. An inbuilt multiturn absolute encoder ensures position precision in the motor's digital servo feedback system. Proper housing alignment and mechanical interface stability are made possible by the 130 mm centering diameter. The < is an ideal component for servo-controlled systems that require position control and torque stability. An improvement in torque and current limits is achieved through surface cooling, which optimizes the performance.
