MDD025B-N-100-N2G-040PA1
The Bosch Rexroth Indramat MDD025B-N-100-N2G-040PA1 is an AC synchronous motor in the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where controlled current is converted into repeatable rotary motion for coordinated axes in automated assembly lines, small pick-and-place robots, and inspection spindles. Its compact frame allows the motor to be mounted close to the load, which helps reduce reflected inertia and improve response on short-cycle motion tasks. This layout is useful in machines that need precise positioning without giving up valuable installation space.
At standstill, the rotor can develop 0.60 Nm of continuous torque, which indicates the static load the motor can support without overheating. A permanent-magnet design and an integrated blocking brake rated at 1.0 Nm help hold vertical or indexing shafts when power is removed. During operation, the motor sustains a nominal speed of 10000 rpm, allowing high-cycle equipment to complete frequent positioning moves. The motor has a centering diameter of 40 mm, a size code of 025, and a B length that suit compact flange-mounted assemblies. Standard housing and standard dynamic balancing help limit vibration and support smooth running at high speed.
Service connections are located on side A, and the keyed power and feedback connector helps keep wiring straightforward. Rotor angle is reported through resolver feedback, which supports sinusoidal commutation and stable closed-loop control in electrically noisy environments. This feedback method also supports accurate speed regulation during frequent starts and stops. The hardened steel shaft uses a keyway and is provided on the drive side as a standard shaft end. A durable shaft seal protects the front bearing area against lubricant loss and coolant entry, which helps the motor remain suitable for compact CNC, packaging, and pick-and-place equipment.
