Product Description:

The MDD025A-N-100-N2G-040PR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it turns commanded current into precise rotary motion for compact, high-speed automation axes. The unit combines a small frame with a standard housing, giving machine builders a compact option when several motors must fit into limited installation space. Its format suits small handling units and other applications where available mounting room is restricted.

At standstill, the rotor delivers a continuous torque of 0.33 Nm, enough to maintain light loads without overheating. When the controller excites the windings at rated frequency, the shaft reaches 10000 rpm for fast traverse or spindle duties. Position data is provided by resolver feedback for closed-loop control. Power and feedback conductors exit on the motor's right side through a connector, which helps simplify cable routing in tight layouts. The shaft is machined with a keyway to transmit torque without slip, and the motor is supplied without a blocking brake, so external holding force is required when the axis must remain fixed. Standard balancing and the connector arrangement support stable operation during normal drive movement.

Mechanical integration is supported by a centering pilot of 40 mm that aligns the flange to gearboxes or adapter plates with minimal runout. Contaminant ingress is limited by the fitted shaft seal, permitting installation near coolant spray or fine dust. The motor's frame code 025 and length code A keep the overall dimensions compact while still accommodating the resolver and stator. A single-ended shaft is supplied, so there is no side B extension behind the motor. This leaves the rear area clear for nearby couplings, brackets, and adjacent machine components. The layout also helps when the motor must be installed in closely spaced assemblies.
