Product Description:

The MDD093C-N-030-N2L-110PA2 synchronous motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled three-phase inverter power into precise rotary motion for indexing tables, packaging spindles, and gantry axes. The model uses the C length code with a standard housing, giving an intermediate torque range while keeping the frame compact. In automated lines, it provides repeatable speed and position so sensor timing and PLC sequences remain aligned with mechanical movement.

This motor carries a centering flange diameter of 110 mm, enabling direct seating in machine frames without additional sleeves. Power and feedback conductors exit on Side A, which can simplify cable routing when the drive end faces the machine interior. A compact multi-pole connector handles both stator and feedback wiring, keeping the electrical interface compact and easy to route. The rotor reaches a synchronous speed of 3000 rpm, and gearing or belt ratios can be selected around that value to suit the machine duty. Frame code 093 identifies the motor size used for this design. For vertical axes or emergency stops, an integrated blocking brake supplies 22 Nm of holding torque, keeping the load fixed when the inverter is disabled.

Closed-loop operation depends on the built-in digital servo feedback (DSF), which returns real-time rotor position to the controller for tight velocity and torque loops. An internal shaft seal keeps lubricant in and contaminants out, allowing use near coolants or fine dust without external covers. The output shaft uses a keyway so pulleys or couplings can transmit torque through positive engagement. This arrangement helps reduce the chance of slip when the axis changes speed or direction under load.
