Product Description:

The MDD025B-N-100-N2K-040PR1 is a compact AC servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for connection to digital drive controllers, it delivers precise position and speed regulation to small axes, pick-and-place heads, and spindle attachments in automated machinery. Its integrated absolute encoder returns real-time rotor position, allowing the drive to close tight current and velocity loops without additional feedback hardware.

The motor seats against mounting fixtures through a centering pilot of 40 mm, ensuring coaxial alignment with gearboxes or couplings. At standstill it can produce a continuous shaft torque of 0.60 Nm, enough to hold lightweight loads without thermally overloading the stator. For rapid cycle applications, the electromagnetic design supports a nominal speed of 10000 min⁻¹, providing high linear velocities when paired with low-ratio transmissions. Electrical safety during power-off is enhanced by the integrated blocking brake, and its braking system is rated for repetitive engagement.

The brake delivers up to 1.0 Nm of holding torque, allowing vertical axes to remain locked when the drive is disabled. Mechanical proportions follow size code 025 and length code B, giving a short body that fits densely populated cabinets. Power is transferred through a keyed shaft, identified by the keyway designation, and a shaft seal is installed to limit lubricant migration into the motor interior. Position feedback utilizes Resolver feedback, which tolerates higher temperatures and vibration than optical devices while still providing absolute angle information for commutation.
