Product Description:

The MDD025C-N-100-N2K-040ME0 is a compact synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is intended to supply controlled rotary motion to small axes in automated assembly equipment and electronics machinery. A housing built to the series’ standard mechanical profile allows easy exchange with other 025-frame units, while the C-length stator gives the winding stack enough active iron for its speed rating. Standard dynamic balancing keeps vibration low when the shaft accelerates toward nominal velocity.

The motor’s nominal speed is 10000 min⁻¹, enabling high-cycle positioning when it is driven by a matched controller. At standstill it can deliver 0.90 Nm of continuous torque; this value defines how much static load the axis can hold without overheating. A centering diameter of 40 mm fits the flange pilot commonly used on miniature gearboxes, and the mechanical interface is completed by a key-slotted shaft and a standard single-ended configuration that omits a side B extension. Power and feedback conductors exit on the Left side, simplifying cabinet routing in machines where the motor is mounted with its cable gland facing the drive enclosure. The unit is supplied without a blocking brake, so any holding function must be provided by the drive or external mechanics. There is no shaft seal, which limits use to clean, dry environments.

A molded connector on a connecting cable with coupling unit links the stator windings to the inverter and establishes the signal path for the integrated absolute encoder. Position data from this device is converted by the drive using resolver feedback, giving multiturn reference without battery backup. The key-slotted output spindle is cut to a keyway profile for positive torque transmission to couplings or miniature pulleys. Together with the standard housing and balancing features, these electrical and mechanical attributes allow the 025-frame motor to fit densely packed servo manifolds where rapid motion, cable flexibility, and precise feedback are required.
