Product Description:

The MDD071A-N-040-N2S-095PL0 is a permanent-magnet synchronous motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into regulated rotary motion for positioning, indexing, and velocity loops in automated machinery. Its electromagnetic design uses permanent magnets on the rotor and a three-phase stator winding, enabling high torque density in a compact package. That combination makes the motor suitable for machine axes that need repeatable motion without a large installation footprint.

This model is balanced to a standard grade to help minimize residual vibration at high speed. A centering diameter of 95 mm locates the housing in a pilot seat, keeping the shaft concentric with gearboxes or couplings. When powered, it can deliver 2.2 Nm of continuous standstill torque, providing holding force for static loads while thermal limits are observed. During dynamic operation, the rotor can reach 4000 rpm, which suits fast cycle duties. Power and feedback conductors exit on the left side through a keyed connector, which can simplify cable routing in multi-axis racks. The internal encoder provides digital servo feedback, allowing the controller to close position and speed loops with high resolution. A machined shaft with a keyway transfers torque directly to pulleys or pinions without slippage.

The front bearing area includes a shaft seal, which helps retain lubricant and reduce contaminant entry. The motor uses a standard housing and length code A, giving a compact package under the size code 071 for tight mounting spaces. Its shaft end is supplied in the standard configuration without an auxiliary extension on side B, which helps in confined coupling layouts and keeps rear clearance requirements low. The unit is delivered without a blocking brake, so any load-holding requirement must be handled by an external mechanism or by drive torque.
