MDD025A-N-100-N2K-040MR1
The MDD025A-N-100-N2K-040MR1 is a rotary drive component manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts electrical power into precise mechanical rotation for small-frame axes in industrial automation. Its integrated feedback device communicates rotor position to the drive, allowing tightly regulated velocity and torque profiles for packaging systems, handling equipment, and electronics assembly machines.
At standstill, the motor can deliver 0.33 Nm of continuous torque, which is suitable for holding and indexing light loads without reaching thermal limits. Once energized, it can accelerate to a nominal speed of 10,000 rpm, which suits high-cycle pick-and-place or spindle duties where short positioning times are important. A blocking brake rated for 1.0 Nm is fitted, and this electromagnetic device locks the shaft during power-off conditions so suspended mechanisms do not drift. Mechanical alignment is supported by a 40 mm centering diameter that helps locate the housing accurately in the machine frame. Power is transferred through a keyway shaft, providing positive torque transmission to pulleys or couplings.
The motor body uses standard balancing to reduce residual vibration at rated speed, and the housing is supplied in the standard form used for this series. The 025 size code indicates the stator diameter, while length code A identifies the short axial format used in compact multi-axis gantries. Feedback to the controller is provided through resolver feedback, which supplies an analog position signal to the drive. Electrical and feedback conductors exit on the right side through a multi-pin connector, which helps with cable routing in tight cabinets. The shaft is supplied without a side B extension and without a shaft seal, so external protection is needed in environments with fluid spray.
