Product Description:
The MDD093A-N-020-N5L-110PB1 is a servo motor made by Bosch Rexroth Indramat. It is part of the MDD series, which is made to help automation systems do jobs that need to be precisely controlled. The motor has digital servo feedback built in, which lets you control the exact position and speed.
The MDD093A-N-020-N5L-110PB1 AC servo motor has a blocking brake built in that can hold 11.0 Nm of power. At rest, the constant force is 9.2 Nm, and it rises to 12.0 Nm as the surface cools. At rest, the continuous current is measured at 10.2 A, and it goes up to 13.3 A when surface cooling is used. The highest torque that can be used is 28.6 Nm. With no load on it, the motor can draw up to 45.8 A at its peak. The moment of inertia of the rotor is 22 × 10⁻4 kg·m², which allows good acceleration response. At 20°C, the torque constant is given as 0.90 Nm/A. The standard speed for the MDD093A-N-020-N5L-110PB1 is 2000 min⁻1. The temperature time constant is 50 minutes when the surface is not cooled and 45 minutes when it is. The power plug is on side B so that the organized cables can be lined up correctly. For reliable encoder-based control that meets the needs of industrial automation, the feedback system uses digital servo feedback.
The MDD093A-N-020-N5L-110PB1 AC servo motor weighs 13.0 kg altogether, not counting the brake that helps keep the structure balanced while it is being mounted. The output shaft has a keyway that meets the requirements of DIN 6885. The centering diameter is given as ø110 mm, which allows for safe alignment with the mounting interface. The motor has a thermal design that lets it handle longer duty cycles when certain conditions are met.
