Product Description:

The MDD071B-N-040-N2L-095PB0 synchronous motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers and delivers controlled rotary motion to axes in automated machinery such as positioning tables and packaging spindles. In operation, the motor converts commanded current from a matching drive into proportional torque and speed for accurate, repeatable motion. This arrangement supports stable acceleration, controlled stopping, and precise speed changes during normal machine cycles.

Its nominal speed is rated at 4000 rpm, which gives the motor a high operating speed for dynamic servo applications. A continuous standstill torque of 4.4 Nm indicates the static load the motor can hold without overheating during dwell periods. Accurate mechanical alignment is supported by a 95 mm centering diameter, which helps the flange seat concentrically against the mounting surface. Cabling exits on side B, helping keep power and feedback leads away from the machine working face. Closed-loop control data is returned through digital servo feedback (DSF), which provides rotor position information for precise velocity and position control.

Power and encoder lines use a removable connector, which allows quick connection and disconnection without re-terminating wires. The output shaft has a keyway, providing positive torque transmission to pulleys or couplings that rely on a form-fit connection. The motor is supplied with a shaft seal, which helps reduce the entry of contaminants along the shaft opening when used with an appropriate coupling cover. The motor uses frame size 071, giving it a compact housing that fits mid-range servo axes where installation space is limited. This frame size supports a balance of torque capacity and installation footprint in general automation equipment.
