Product Description:

The MDD065B-N-040-N2M-095PA1 is a synchronous servo motor developed by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended to work with digital drive controllers, translating commanded current into precise speed and torque so automated equipment such as pick-and-place heads or indexing tables can follow programmed motion profiles. Permanent magnets on the rotor and an electronic control loop make the unit suitable for repetitive industrial positioning where accuracy and repeatability are required. In servo applications, the drive continuously adjusts current to match changing load conditions during motion. That behavior supports stable tracking in equipment that performs frequent starts, stops, and short positioning moves.

Mounting is simplified by a centering diameter of 95 mm, while standard dynamic balancing minimizes vibration when the shaft approaches its nominal speed of 4000 rpm. At standstill the motor can deliver 1.5 Nm of continuous torque, providing holding force for static cuts or clamps. Position data comes from an integrated multi-turn absolute encoder that works in tandem with digital servo feedback to close the control loop with the drive. Electrical power and feedback lines terminate through a sealed connector, and the motor uses a shaft seal to limit dust or coolant ingress around the output journal. The motor follows size code 065 with length code B, uses a standard housing, and omits a shaft extension on the rear side so less installation depth is required.

A blocking brake is fitted and applies 3.0 Nm of torque to prevent unintended motion during power loss. Torque from the servo is transferred through a keyway shaft, allowing rigid coupling to pulleys or gearwheels without slip. Cables exit on side A, keeping service loops short when the motor is installed close to machine frames. This cable position can help simplify routing where space around the drive end is limited.
