MDD025B-N-100-N2G-040PL1
The MDD025B-N-100-N2G-040PL1 is a synchronous servo motor from the MDD Synchronous Motors series built by Bosch Rexroth Indramat. It is intended for use with digital drive controllers and converts regulated current into fast rotary motion for positioning tables, compact gantries, and other automated axes. This makes the unit suitable for packaging, light handling, and indexing tasks that require quick response in a small motor envelope. Its compact format also fits machines where installation space is limited and stable closed-loop motion is required through repeated cycles.
At standstill, the rotor sustains a continuous torque of 0.60 Nm, and when energized the speed setpoint can be driven to 10000 rpm for fast cycle execution. A blocking brake rated at 1.0 Nm locks the shaft during power-off states, which helps prevent drift on vertical or indexing axes. Position information is returned through resolver feedback, allowing the controller to track rotor angle for commutation and speed regulation. Radial alignment on the mounting face is maintained by a 40 mm centering diameter, and standard dynamic balancing helps keep vibration low at high speed. Resolver-based feedback is also useful in installations that prefer a rugged analog feedback device.
Cabling is routed through a detachable connector that faces the left side of the end bell, which suits layouts where bundled motor leads follow a single cable path. The shaft uses a keyway for positive torque transmission, and the motor size code 025 identifies the external frame used in this series. The motor has with a shaft seal protection at the shaft exit, which helps protect the bearings from coolant splash or light dust. Motor length code B and the standard housing keep the overall form consistent for mounting in compact servo assemblies. The sealed shaft arrangement is useful where occasional splash or airborne contaminants are present near the drive end.
