MDD025B-N-100-N2G-040MA1
The MDD025B-N-100-N2G-040MA1 is a compact synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for direct coupling to digital drive controllers, where it converts controlled current into precise rotary motion for small indexing tables, light pick-and-place axes, or auxiliary spindles in automated production lines. As a synchronous motor, it supports accurate rotor control during rapid starts, stops, and speed changes in compact machine sections.
During static load conditions, the rotor can deliver a continuous torque of 0.60 Nm, so the motor can hold position against frictional or gravitational forces without thermal overload. Under rated excitation, the shaft can reach a nominal speed of 10000 rpm, supporting rapid cycle times in machinery that demands high throughput. A blocking brake is integrated, and its holding capability is 1.0 Nm of brake torque to keep the axis locked when power is removed. Position and velocity loops in the drive are closed with resolver feedback, giving absolute rotor angle information at any speed. Mechanical alignment to the machine frame is guided by a centering diameter of 40 mm, which establishes concentricity between the motor flange and the driven element.
Cabling exits on side A, simplifying layouts where the motor is mounted in tight enclosures or routed alongside neighboring axes. The shaft is machined with a keyway to provide a positive drive interface for pulleys or couplings, and the motor is supplied without a shaft seal, making it suitable for clean, dry installations. The rotor and fan components use standard balancing, which helps keep vibration within acceptable limits during high-speed operation. A connector-based feed-through and the B-length stator package help the motor fit compact multi-axis assemblies that need repeatable motion and efficient use of space.
