Product Description:

The MDD025A-N-100-N2K-040PD0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied as part of the MDD Synchronous Motors series. Designed to pair with digital drive controllers, it converts three-phase power into regulated mechanical rotation, enabling precise axis movement in automated pick-and-place modules, small conveyors, and compact fixtures. With its compact frame and low inertial load, the motor fits machines where limited mounting space and high dynamic response are critical. It is suited to small servo axes that need quick reversing moves and steady closed-loop motion.

The motor has a nominal speed of 10000 min⁻¹, allowing short positioning times during rapid acceleration profiles. At standstill the motor delivers 0.33 Nm of continuous torque, which is suitable for light clamping duties and stable servo hold behavior. A centering diameter of 40 mm simplifies alignment on standard mounting flanges and helps keep runout within tolerance. Electrical and feedback conductors exit on Side B, so cables can be routed away from the mechanism to reduce loop area and electromagnetic interference. Power is supplied through a connecting cable with coupling unit, which provides a compact electrical connection and keeps the motor interface easy to access in tightly spaced assemblies.

Position information is derived from resolver feedback, giving sine-cosine signals that remain accurate at high rotational speeds and resist electrical noise from nearby inverters. The motor is supplied without a blocking brake, so holding force during power-off conditions must be provided by the drive or an external clutch if the load cannot coast safely. A fitted shaft seal guards the bearing set against coolant spray and fine dust, which helps protect internal rotating parts in industrial service. The keyed shaft end uses a keyway to transmit torque reliably into couplings or pulleys without relying only on frictional clamping. Standard balancing, housing geometry, the A-length code, and the 025 frame size keep vibration low and support installation in compact machine layouts.
