MDD071B-N-060-N2M-095GA0
Bosch Rexroth Indramat manufactures the MDD071B-N-060-N2M-095GA0 synchronous motor within its MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts current from Indramat drives into precise rotary motion for axes that demand repeatable speed and position control in automated lines, machine tools, and material-handling cells. Its compact frame and electronic feedback allow the drive to close velocity and position loops directly, reducing mechanical compliance and improving throughput across multi-axis installations.
The motor develops a continuous standstill torque of 4.4 Nm, giving the drive enough holding force to resist static loads until motion begins. The motor has a nominal speed of 6000 min⁻¹, which supports high throughput when the control system commands rapid indexing. Mechanical alignment during installation is aided by a centering diameter of 95 mm, which matches flange patterns for the 071 frame size. Position information is supplied by an integrated multiturn absolute encoder, and that signal is routed to the controller through digital servo feedback (DSF) so the axis can recover its position after power cycling. The B-length stator section balances thermal area with a short overall package, and the Side A connector layout simplifies cable routing.
The motor uses a plain shaft on the drive side, while the opposite end is not extended. Contamination ingress is limited by a shaft seal that works with the motor’s IP-protected housing. Vibration is controlled through standard balancing, which permits direct coupling to gearboxes without additional trim. For stop-and-hold requirements, the motor is delivered without a blocking brake, so applications that need power-off holding must rely on external clamps or drive torque. The standard housing retains the thermal path used across the series, and the Side A connector orientation remains accessible after panel mounting.
