MDD025B-N-100-N2G-040FA1
The MDD025B-N-100-N2G-040FA1 is a brushless servo motor manufactured by Bosch Rexroth Indramat and supplied in the MDD Synchronous Motors series. Intended for use with digital drive controllers, the motor converts controlled current into rapid and repeatable shaft rotation for automated axes such as pick-and-place gantries and packaging spindles. Its form factor follows motor size 025 with length code B, allowing it to fit into tight mechanical spaces without giving up the response expected from a servo axis. Used with a matching controller, it supports closed-loop motion in applications that require fast speed changes and consistent positioning. The brushless design also removes commutator wear, which helps maintain smooth operation over repeated duty cycles in automated equipment.
Mechanically, the motor reaches a nominal speed of 10,000 rpm, so the drive can command fast indexing without gear reduction. Continuous torque at standstill is rated at 0.60 Nm, which supports static holding and low-speed operation on light-duty axes. The centering shoulder measures 40 mm in diameter, keeping the motor aligned with the machine interface during installation. Power and feedback conductors exit on Side A through a keyed connector, which keeps all cable connections at one end of the housing and helps prevent incorrect mating. Standard balancing helps limit vibration during high-speed operation, and the motor uses the standard enclosure style of the series. This cabling arrangement is useful where the motor is mounted close to guards, slides, or tooling plates.
A blocking brake is integrated and develops 1.0 Nm of static torque to hold vertical or suspended loads when power is removed. Rotor position is tracked by resolver feedback, giving the controller continuous angle information across the speed range for commutation and control. The output uses a plain shaft in a single-ended arrangement, so there is no shaft extension on side B. Because the motor is supplied without a shaft seal, it is best installed where oil, coolant, and washdown spray cannot reach the bearing interface. This layout suits clean machine areas where direct coupling and compact packaging are more important than liquid protection at the shaft end.
