MDD025A-N-100-N2K-040PF0
The MDD025A-N-100-N2K-040PF0 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is supplied for use with digital drive controllers and is intended to deliver high-speed rotary motion in compact automation axes. The motor converts electrical energy from a matched inverter into precise mechanical torque for positioning and velocity control in production lines, electronic assembly tables, and test fixtures where small frame dimensions and low inertia are important. Its compact format also suits indexing units, light transfer devices, and other space-limited machinery that depends on fast response and repeatable motion.
The motor develops a continuous standstill torque of 0.33 Nm, allowing light loads to hold steady without overheating. Dynamic operation reaches 10000 rpm, a speed that suits high-throughput pick-and-place tasks or spindle-style duty. Accurate mechanical centering is achieved with a 40 mm pilot diameter, and the shaft uses a keyway for positive drive coupling. Feedback for real-time control is provided through resolver feedback, which supplies rotor position signals to the drive during operation. The pilot diameter and keyed shaft help maintain alignment between the motor and the driven load during rapid speed changes. The motor also uses standard rotor balancing, a standard housing, frame size 025 geometry, and the short A length code to keep the overall envelope compact while supporting stable installation.
A right-hand power and feedback exit keeps the cable path on one side of the housing and supports orderly routing in compact machine spaces. Because the unit is supplied without a blocking brake, power-off holding must be provided by drive torque or an external clamp when the axis must remain fixed at standstill. The output shaft uses a shaft seal to limit ingress, and stator conductors are routed through a connecting cable with a coupling unit for straightforward cabinet wiring. The motor uses a single-ended shaft arrangement, so there is no shaft extension on side B.
