MDD025C-N-100-N2K-040GR0
The MDD025C-N-100-N2K-040GR0 is a compact synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for pairing with digital drive controllers, converting commanded current into rapid, precise rotation that positions small axes in automated assembly, electronics handling, or light machining. Its compact frame and short housing length allow the motor to fit tightly spaced multi-axis gantries while still supporting the high speeds used in short-cycle industrial processes.
At stall, the rotor can deliver a continuous torque of 0.90 Nm, which is the sustained mechanical load the motor can carry without exceeding thermal limits. The nominal operating speed reaches 10000 rpm, so rapid indexing can be achieved without external gearing. A centering shoulder of 40 mm seats the housing accurately in the mounting bore and helps keep radial runout low. Position information is returned through resolver feedback, which offers strong immunity to electrical noise in closed-loop control. To block coolant or dust migration along the shaft line, the output end is supplied with a shaft seal. Standard dynamic balancing helps reduce vibration during high-speed operation.
For wiring, power and feedback plugs are oriented to the right, placing them away from moving couplings and simplifying strain-relief hardware. A circular connector interface enables quick connection without soldering or crimping. The lightweight stator helps keep inertia low for swift acceleration and deceleration. Because the assembly is shipped without a blocking brake, any vertical or overhung load must be secured by the drive or by a mechanical latch when supply power is removed. The motor has a plain shaft, a standard one-ended shaft configuration, and a standard aluminum housing.
