MDD025A-N-100-N2G-040MC1
The MDD025A-N-100-N2G-040MC1 is a brushless synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, it delivers controlled rotary motion to compact machine axes in packaging lines, electronics assembly stations, and small handling robots. The motor’s compact housing supports installation where moving mass and available space must be kept low. Its integrated blocking brake allows safe holding of vertically mounted loads when the controller is disabled.
At standstill, the motor can produce a continuous torque of 0.33 Nm, providing the baseline force for accurate positioning without overheating during static duty. Its rated mechanical speed reaches 10,000 rpm, so paired drives can command rapid cycles while staying within the rotor’s magnetic and bearing limits. The integrated blocking brake exerts 1.0 Nm of holding torque, enabling the shaft to remain fixed when power is removed. Precise centering during mounting is supported by a 40 mm centering diameter, while all power and feedback conductors exit on side A to simplify cable routing in compact machine layouts. Motion feedback is supplied through resolver feedback, providing rotor angle signals that remain reliable in electrically noisy environments.
The shaft is machined with a keyway to secure couplings and help prevent slip during dynamic load changes. The housing is delivered without a shaft seal, so the motor is best installed in clean, dry areas or used with external sealing where fluid exposure may occur. With the compact frame classification of 025, length code A, and standard balancing, the unit suits lightweight gantry heads and other small axes that benefit from low inertia. A connecting cable with a coupling unit completes the interface, and the shaft end is present only on the drive side to keep the overall length compact.
