Product Description:

The MDD071A-N-040-N2T-095GA2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is used with digital drive controllers to convert electrical commands into precise rotary motion for conveying, indexing, and tool-positioning tasks in industrial automation. This motor is suited to axes that require repeatable response during starts, stops, and speed changes. Its electromagnetic design supports closed-loop operation, so speed and torque remain stable under changing loads in production lines and handling equipment.

A centering diameter of 95 mm helps align the flange with adjoining machinery for accurate installation. Power and feedback conductors exit on side A, and the factory-fitted connector reduces the need for separate terminal-strip wiring. At standstill, the motor delivers 2.2 Nm of continuous torque, which is suitable for small clamp or feed axes, while the integrated blocking brake provides 6.5 Nm of holding torque to keep the shaft in place when power is removed. Position data come from an integrated multiturn absolute encoder, which supplies multi-revolution position information so the drive can retain axis reference after controlled stops.

The motor has a nominal speed of 4000 rpm, making it suitable for fast positioning and speed-controlled motion in the 071 frame size. Command and diagnostic signals are transmitted through digital servo feedback (DSF), which gives the drive direct rotor data for precise commutation and stable control behavior. Mechanical output is delivered through a plain shaft, and the front bearing area uses a shaft seal to help limit contamination ingress. The motor has length code A, and the omitted shaft end on side B shortens the housing to save installation space where a compact overall length is preferred.
