Product Description:

The MDD065A-N-040-N2M-095PB0 is a synchronous servo motor in the MDD Synchronous Motors series from Bosch Rexroth Indramat. It is intended for use with digital drive controllers and supplies rotary motion to axes in automated assembly, material handling, and packaging lines. The compact frame size 065 and A-length housing help it fit tight machine layouts where mounting space is limited. This layout is well suited to applications that need responsive motion without using a large motor envelope. It can be used on conveyor axes, pick-and-place units, and similar mechanisms that rely on repeatable servo response.

This motor provides a continuous standstill torque of 0.8 Nm, so it can hold a steady load at zero speed within normal thermal limits. Its nominal speed is 4000 rpm, which supports fast indexing cycles and quick repositioning in servo-controlled stations. A centering diameter of 95 mm provides an accurate reference for flange alignment with couplings or gearboxes. Position and velocity data are returned through digital servo feedback from an integrated multi-turn absolute encoder, allowing closed-loop control and position retention after power cycling. The feedback system also lets the connected drive monitor rotor position continuously during changes in speed and load.

Power and feedback leads exit on side B, and the motor uses a connector for straightforward cable attachment. Rear cable exit can help keep wiring clear of couplings and other driven elements at the mounting face. Torque is transmitted through a keyway shaft with a shaft seal, which helps limit lubricant ingress at the bearing area. The motor is supplied without a blocking brake, so any load that must remain fixed during power-off needs an external holding method. Standard dynamic balancing helps reduce vibration during high-speed operation, and the motor has a single shaft end on the drive side to keep the overall length short in installations with limited axial space.
