MDD025A-N-100-N2G-040MF0
The MDD025A-N-100-N2G-040MF0 is a compact synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is engineered to drive small axes on digital motion controllers, where rapid speed changes and precise positioning are required in automated assembly stations, electronic component handlers, or light pick-and-place modules. By combining low rotor inertia with high permissible shaft speed, the unit provides fast response for short-cycle tasks while remaining compatible with the manufacturer’s drive systems and diagnostic tools.
The motor uses a centering pilot of 40 mm to align the flange during installation. It has length code A within size class 025, and standard balancing allows direct coupling to lightweight loads without additional counterweights. Housing surfaces are standard for cabinet-mounted operation, electrical conductors exit on the right side to match right-hand cable trays, and the shaft end is single-sided to save space at the rear. Continuous stall output reaches 0.33 Nm, and the rotor can reach a nominal speed of 10000 rpm so high linear velocities remain possible after transmission reduction.
Position is reported through Resolver feedback, which tolerates electrical noise created by high-frequency inverters and supports stable motor control. Power and sensor leads are bundled in a connecting cable with coupling unit, which is useful where machine-frame clearance is limited and separate connection points would take more space. Because the rotor is manufactured without a holding brake, static locking must be handled by the drive or by external clamps when the axis is stopped. Torque is transferred through a keyway shaft, allowing slip-free attachment of miniature pulleys or spur gears for compact drive arrangements.
