Product Description:

Bosch Rexroth Indramat’s MDD025B-N-100-N2K-040PD0 belongs to the MDD Synchronous Motors series and is supplied as a motor for digital drive controllers. Its compact frame is intended for high-speed positioning and light mechanical duties in automated assembly cells. The unit is built in a standard housing that protects the stator laminations without adding excess mass, allowing it to be mounted close to the motion axis where space is limited in multi-axis machines.

The mechanical geometry is fixed by a centering diameter of 40 mm, so the motor fits pilot recesses commonly used on miniature gearboxes. With a continuous standstill torque of 0.60 Nm, the rotor can hold loads without overheating during static clamping sequences. A nominal speed rating of 10,000 rpm pairs this modest torque with very high shaft velocity, giving adequate power when coupled to belt transmissions or direct-drive spindles. Dynamic balance is maintained to a standard grade, and the rotor length code B helps keep inertia low for rapid acceleration. All power and feedback connections exit on Side B, simplifying cable routing along compact linear axes. The motor uses a size 025 frame.

Feedback is provided through resolver feedback and an integrated absolute encoder for position and speed control. Power is supplied through a connecting cable with coupling unit, allowing quick disconnection without disturbing conduit runs. The drive end uses a keyway shaft to help prevent pulley slip, and a shaft seal blocks cutting fluid or dust from entering the front bearing. Because the motor is delivered without a blocking brake, holding force at power-off must come from drive torque or an external clamp. The standard shaft end configuration omits a rear shaft, which reduces overall length and prevents drive-through from the opposite side.
