Product Description:

Bosch Rexroth Indramat's MDD025A-N-100-N2K-040PL0 is part of the MDD Synchronous Motors series and is matched to digital drive controllers. This synchronous servomotor converts commanded current into angular displacement for small pick-and-place heads, miniature indexing tables, and tooling spindles that require very high speed with limited torque. The compact actuator combines the 025 frame code with the A-length stator, allowing direct integration where axial space is limited and low rotor inertia is beneficial for rapid reversals. Its small envelope suits compact assemblies where fast servo response is more important than high continuous torque.

Mechanical interfaces include a centering pilot of 40 mm, and the rotor uses standard dynamic balancing so supplementary trim weights are unnecessary. Both power and feedback conductors exit on the left side through a keyed circular connector, which helps with cable routing in crowded cabinets and keeps the connection point consolidated at one end of the motor. Under rated thermal conditions, the motor maintains 0.33 Nm of continuous standstill torque, enough to resist light static loads in compact mechanisms without additional clamping in every application. Position is captured by an integrated absolute encoder, while servo loops use resolver feedback carried in the same hybrid lead.

The drive package is delivered without a blocking brake, so stationary holding torque after power loss must be supplied by the attached mechanics. During operation, the rotor can reach 10000 rpm, supporting fast-cycle machines that still benefit from the motor's compact housing. Shaft power is transmitted through a single-ended steel journal machined with a keyway, while the opposite end remains closed for the single-sided layout. A contact surface fitted with a shaft seal helps prevent lubricant or coolant intrusion at the shaft exit, which is useful where nearby machine elements are exposed to fluid or fine debris.
