Product Description:

The MDD025C-N-100-N2K-040PB0 is a compact synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for use with digital drive controllers, this motor supplies high rotational speed and controllable torque to automated axes in industrial equipment. It converts drive current into precise mechanical motion so that small loads can be indexed accurately, rapid positioning profiles can be followed, and steady velocity can be maintained during continuous operation. That operating profile suits compact packaging stations, transfer units, and other machinery that depends on quick response in a limited installation space.

The motor reaches a nominal speed of 10000 rpm, indicating how fast the rotor can turn under rated conditions. It provides 0.90 Nm of continuous standstill torque, allowing the drive to hold a load at zero speed without overheating. Mounting is centered by a 40 mm pilot, and the rotor is balanced to a standard grade to help limit vibration during high-speed operation. Cables exit at Side B through a single connector, which keeps the electrical interface compact. The motor has frame size 025 with length code C, and the housing uses the standard sealed version. Rear cable exit can also simplify routing where the machine layout offers limited side clearance.

Position data is supplied by an integrated feedback package that combines an integrated absolute encoder for multi-turn position capture with resolver feedback for stable speed control. Torque is transmitted through a shaft with a keyway, and a shaft seal helps prevent oil or coolant from reaching the bearings. The shaft end uses the standard single-ended geometry, so there is no second shaft extension on the opposite side. Because the motor is supplied without a blocking brake, an external holding method is needed when a vertical axis must remain fixed at standstill. This layout supports compact servo axes that require fast starts, precise stops, and consistent position tracking during repeated motion cycles.
