Overview
The Rexroth MDD093B-N-030-N2M-110PB0 is a precision permanent magnet, digital AC servo motor manufactured by Bosch Rexroth Indramat. Part of the proven MDD synchronous motor series, this unit delivers consistent 14.5 Nm continuous torque at standstill with a 3000 min nominal speed. Its integrated multiturn absolute encoder and digital servo feedback system enable repeatable, high-accuracy motion control without requiring a separate incremental encoder.
Key Features
- 14.5 Nm continuous torque at standstill with high power density
- Digital servo feedback with integrated multiturn absolute encoder
- Electronic commutation design eliminates brushes, reducing mechanical wear and maintenance
- Keyway output shaft with 110 mm centering diameter for standard coupling interfaces
- Side B connector for straightforward integration with Rexroth Indramat digital drive controllers
