Product Description:

The MDD065B-N-040-N2M-095PA0 synchronous motor is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it forms the electromechanical link between the controller’s output stage and the machine shaft, delivering commanded speed and position values in automated production lines. The unit uses a standard housing and standard rotor balancing, so it fits existing machine layouts without special counterweights or external enclosures.

Under continuous electrical excitation, the motor reaches a nominal speed of 4000 rpm, giving the axis a wide operating range for moderate-inertia loads. At standstill, it can deliver 1.5 Nm of continuous torque, which supports holding or low-speed indexing when control current is applied. Accurate mounting is supported by a centering diameter of 95 mm, which keeps the motor face concentric with couplings or gearboxes. Command and feedback lines are exchanged through a single connector, and the returning signals use digital servo feedback so the controller can maintain a high-resolution position loop. A dedicated shaft seal helps limit lubricant migration and protects the internal bearings from splash or fine dust.

The mechanical interface includes a keyway on the output shaft so torque can be transferred without slip. An integrated multiturn absolute encoder preserves position data across power cycles, allowing the axis to retain position information after power returns. All electrical terminations are oriented toward Side A, which can simplify cable routing in narrow cabinets. The motor is supplied without a blocking brake, so static holding torque must be provided by the drive or by an external clamp when needed. The model carries size code 065 and length code B, and its standard shaft end does not include a side-B extension, which helps reduce overall depth in tight assemblies.
