Product Description:

The MDD025A-N-100-N2G-040PR1 is a small-frame synchronous motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it converts commands from the servo amplifier into controlled rotary motion on positioning axes, pick-and-place heads, or spindle drives. By combining permanent-magnet excitation with low rotor inertia, it supports rapid speed changes while maintaining precise torque regulation for automation.

It uses standard rotor balancing so vibration remains within ISO limits, and its housing also uses a standard configuration. The centering pilot measures 40 mm, setting the reference for flange alignment against gearboxes or mounting plates. Continuous stall torque is 0.33 Nm, allowing the motor to hold low-mass loads during static phases without overheating. At a nominal speed of 10000 rpm, the rotor delivers rated power when supplied by the matching drive, giving high surface speed for compact tooling. Position and velocity are closed-loop through resolver feedback, which produces sine-cosine signals with good immunity to electrical noise. A shaft machined with a keyway accepts standard keyed couplings so transmitted torque cannot slip under start-stop duty.

The integrated blocking brake develops 1.0 Nm of static torque to secure vertical or indexing axes when power is removed. Connections exit on the right side through a coded connector, matching the wiring layout of drive cabinets mounted beside the axis. An internal shaft seal prevents lubricant migration along the 025-size shaft, and the shaft end is supplied in the standard single-ended configuration so no hardware projects from side B. With motor length code A, the unit keeps its overall package short and fits installations where axial space is limited.
