Product Description:

Bosch Rexroth Indramat manufactured the MDD093C-N-030-N5L-110PB0 Synchronous servo motor. Automated systems requiring continuous regulation of speed and torque make use of this part, which is part of the MDD093C series. Motors with digital servo feedback allow for very accurate placement. A shaft with a 110 mm centering diameter and a keyway per DIN 6885 is part of the package.

The nominal speed rating for the MDD093C-N-030-N5L-110PB0 Synchronous servo motor is 3000 revolutions per minute. At rest, it generates a constant torque of 19.5 Nm while drawing a constant current of 32.2 A. The inductance of the windings is 2.7 mH, which supports stable current transition. The rotor moment of inertia of 42 × 10⁻⁴ kgm² contributes to consistent speed control in industrial automation systems. The house is designed to improve heat dissipation through natural convection and surface cooling. Its digital motor feedback technique enables closed-loop control with high precision. The motor lacks a blocking brake. The servo motor's power supply is on side B. This arrangement is ideal for systems that require dynamic motion control and predictable torque response in a variety of situations.

The MDD093C-N-030-N5L-110PB0 servo motor's thermal stability is characterized by a 50-minute thermal time constant when operating continuously. Mechanical stability is improved during high-torque operations due to the motor's mass of 22.0 kg. The theoretical maximum torque of 60.6 Nm is provided by a peak current of 145.0 A. At 20 degrees Celsius, the torque constant is 0.61 Nm/A, ensuring efficient torque output per amp. The motor's winding resistance defines a voltage-to-current ratio of 0.23 Ohms. Applications requiring precise torque control and repeatable motion can easily incorporate the design and electrical requirements. The motor is well-suited for use in industrial automation systems that require thermal uniformity and performance stability due to its specifications.
