Product Description:

The MDD071A-N-040-N2S-095GL2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts electrical power into controlled rotary motion for indexing tables, packaging axes, and other automated stations. The unit occupies a medium frame position in the product range and supplies steady torque over a broad speed band to support accurate velocity and position control in industrial machinery. This type of motor is commonly used where smooth low-speed behavior and repeatable positioning are required from the same axis.

At standstill, the motor delivers 2.2 Nm of continuous torque, letting it hold or slowly index loads without extra cooling. During motion it reaches a nominal speed of 4000 rpm, a value suited to high-speed pick-and-place tasks or light spindle duty. To secure vertical or overhung loads when power is removed, the integrated blocking brake develops 6.5 Nm of static holding torque. Position and velocity are returned to the drive through digital servo feedback, enabling precise closed-loop control. The feedback channel helps the drive correct load changes quickly during frequent acceleration and deceleration. Power and signal conductors exit on the left side through a single connector interface, which helps keep cable routing orderly and reduces strain at the motor connection.

A centering diameter of 95 mm aligns the flange against gearboxes or adapter plates, while frame size 071 keeps the motor compact enough for gantry or robot wrist axes. Length code A marks the shortest body in the series, which helps reduce inertia and fits tighter machine envelopes. The output side uses a plain shaft with a fitted shaft seal to limit the entry of coolant mist and dust. The opposite side has no secondary shaft extension, so the rear of the motor can sit close to adjacent machine components, and the standard housing uses sealed bearing seats. This layout also leaves the shaft end easy to connect to couplings, pulleys, or compact gearbox inputs.
