MDD025B-N-100-N2K-040FF0
The MDD025B-N-100-N2K-040FF0 is a synchronous motor in the MDD Synchronous Motors series from Bosch Rexroth Indramat. It is intended for use with digital drive controllers and provides rapid rotary motion for compact automation axes. The size 025 frame with B length suits installations where available space is limited but high shaft speed is still required. In automated equipment, the motor converts regulated current from the drive into controlled shaft rotation, while onboard feedback supports accurate motion response during repeated cycles.
At stall, the rotor can maintain a continuous torque of 0.60 Nm, allowing the axis to hold moderate loads without overheating. The winding and magnet system support a nominal speed of 10000 rpm, which makes the motor suitable for rapid indexing and other high-speed motion tasks. Accurate mechanical alignment is assisted by a 40 mm centering diameter that fits common motor flanges. A plain shaft end transmits motion without keyways, which suits clamp or collet couplings and helps keep rotating inertia low. Position data is supplied through resolver feedback, giving analog signals that the drive uses for angle and velocity calculation across the speed range.
Cabling is routed through a connecting cable with coupling unit, so no separate terminal box is required. All power and signal lines exit on the right side of the housing, which can simplify routing when several motors are mounted in a row. The motor is supplied without a blocking brake, so any holding function must come from the application or an external device. An integrated absolute encoder retains shaft position through power cycles, which can reduce startup motion before normal operation begins. Standard dynamic balancing, a standard housing, and the absence of a shaft seal help keep the motor suitable for high-speed duty.
