MDD065B-N-060-N2L-095GR1
The MDD065B-N-060-N2L-095GR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies closed-loop rotary motion in assembly lines, packaging machines, and material-handling axes where compact size and high speed are required. This arrangement supports repeatable speed control and accurate positioning during frequent starts, stops, and short travel moves. Its B-length housing and size 065 frame support installation in machine layouts that use the MDD mechanical interface. Standard balancing helps maintain smooth operation at high speed. It is suited to compact axes where fast response and a small mounting envelope are both important.
The mechanical interface uses a centering diameter of 95 mm, which aligns the motor housing to a gearbox or mounting flange without additional adapter rings. At standstill, the rotor can deliver 1.5 Nm of continuous torque, allowing light loads to hold position without excessive heat buildup. During operation, the shaft reaches a nominal speed of 6000 rpm, making the motor suitable for rapid indexing and other high-speed axis duties when paired with a compatible inverter. Power and feedback conductors exit on the right side, which can simplify cable routing in layouts where the motor is mounted near a machine sidewall. A keyed circular connector provides the electrical interface and allows the cable set to be attached securely.
The control loop relies on digital servo feedback so the drive can read position data with high resolution for stable motion control. For vertical axes, a blocking brake is included, and it supplies 3.0 Nm of static holding torque to help prevent drift when power is removed. The motor uses a plain shaft, and a shaft seal helps protect the internal bearings from coolant splash and airborne debris. The housing surface is left unpainted to support heat transfer to the mounting surface. This finish also avoids adding an insulating paint layer between the housing and the machine structure. These features support reliable operation in areas exposed to dust, splash, and repeated stopping.
