Product Description:

The MDD025C-N-100-N2K-040MA1 is a synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It functions as a motor for digital drive controllers, supplying velocity and torque to light-duty automation axes such as pick-and-place spindles and compact gantry drives. Within an integrated automation cell, the unit mates directly with a drive amplifier and converts commanded current into rapid, repeatable rotary motion.

The mechanical interface is defined by a centering diameter of 40 mm, allowing precise seating in flanged machine frames. Electrical terminations exit on Side A; the motor uses a Connector plug so power and feedback lines can be removed without opening the housing. At standstill the continuous torque capability is 0.90 Nm, while dynamic operation can reach a nominal rotor speed of 10000 min⁻¹; this combination supports fast indexing with limited thermal loading. Motion accuracy is sustained by an integrated absolute encoder that forwards single-turn position data directly to the drive. The standard shaft end is supplied without a side B extension, so thrust loads are transmitted solely through the front bearing set.

Additional construction details govern stoppage, alignment, and integration. A blocking brake delivers 1.0 Nm of static holding torque so the axis remains fixed when power is off, and the drive verifies position through resolver feedback rather than the digital channel used during motion. Rotating parts are balanced to the standard grade, while the standard housing encloses the 025 frame in the motor length code C configuration. The shaft machining follows a keyway pattern and the nose runs without a shaft seal, conditions suited to dry, cabinet-mounted installations where external contamination is limited.
