Product Description:

The MDD093A-N-040-N2M-130PB1 is a three-phase synchronous servomotor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Supplied as a motor for digital drive controllers, it converts commanded current into rotary motion for positioning tables, pick-and-place heads, and other industrial automation axes where closed-loop accuracy is essential. Its frame falls in the 093 size class and uses standard housing and balancing, making it suitable for general machinery layouts. This motor is intended for servo systems that require accurate torque production across a wide operating range. Its synchronous design allows the drive to regulate motion precisely during positioning and repeatable cycling.

It develops a continuous stall torque of 9.2 Nm, allowing the axis to support static process loads without external gearing. The rated mechanical speed reaches 4000 rpm, which supports fast indexing moves on dynamic machine axes. For load safety during shutdown, the integrated blocking brake supplies 11 Nm of holding torque. Service power and feedback plugs are located on side B, keeping cables clear of the driven machine face, while a 130 mm centering diameter helps align the motor accurately on the mounting surface. Rotor position data return to the drive through Digital servo feedback (DSF), supporting closed-loop control and electronic nameplate detection. The sealed connector interface keeps power and signal terminations compact and protected at the motor housing.

The sensing hardware includes an integrated multi-turn absolute encoder that retains position over power cycles, so the axis can restart without a homing routine. Absolute feedback also improves reference retention after controlled stops or short power interruptions. Output torque is transferred through a hardened shaft with a keyway, and the motor uses a single shaft end on the drive side to conserve space. The shaft is supplied with a shaft seal, which helps limit contaminant ingress during operation. Motor length code A keeps the package depth short, and the standard balancing arrangement helps reduce vibration at higher speeds.
