Product Description:

The MDD071B-N-040-N2S-095PB1 is a synchronous servo motor built by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts electrical power into controlled rotary motion for positioning and speed control in automated machinery. Its electromagnetic design allows commanded current from the drive to be translated into responsive torque, which helps axes follow programmed motion profiles during indexing, feeding, and general servo tasks. This arrangement makes the motor suitable for machines that need repeatable acceleration and stable speed regulation under changing loads.

The motor has a centering diameter of 95 mm and a frame size of 071, giving it a compact installation footprint. Power and feedback conductors exit through a connector on side B, which keeps cable routing concentrated at one end of the housing. A factory-installed shaft seal helps protect the internal bearings from coolant splash and airborne contamination, while standard rotor balancing supports smooth rotation during operation. Under continuous stall conditions, the motor develops 4.4 Nm of torque, and during motion it reaches a nominal speed of 4000 rpm. This operating range fits compact servo axes that need quick response without requiring a larger motor body.

For feedback, the motor uses digital servo feedback (DSF), which returns rotor position data to the controller for closed-loop commutation and speed regulation. A built-in blocking brake provides 3.0 Nm of holding torque to help keep an axis in place when drive power is removed. The output shaft uses a keyway for secure coupling, and the motor has a length code of B, which keeps the assembly compact while accommodating the integrated brake and feedback system. This layout reduces the need for separate external components at the motor and supports clean installation in space-limited machine assemblies.
