Product Description:

The MDD025A-N-100-N2G-040PB0 is a permanent-magnet synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers where compact rotary actuation and rapid speed changes are required to position tooling, pick-and-place heads, or lightweight conveyor sections. By combining high nominal speed with resolver feedback, the unit supports closed-loop control of velocity and angle in automated machinery. This layout is well suited for small axes that must start, stop, and reverse quickly during repetitive machine cycles.

The motor reaches a nominal velocity of 10000 rpm, allowing short cycle times when paired with an inverter. At standstill, it can deliver 0.33 Nm of continuous torque, which is suitable for holding light loads while keeping stator heating low. A centering shoulder diameter of 40 mm aligns the frame accurately against the mounting pilot, and standard dynamic balancing helps limit residual vibration during acceleration. Electrical power and feedback enter through a single Connector on Side B, which helps route the cable toward the rear of the motor in narrow machine enclosures. The size code 025 and length code A indicate the compact body proportions used by this motor.

The drivetrain interface is a keyed shaft, identified as keyway, and it uses a standard single-ended configuration so no secondary shaft projects from the opposite side. An integral oil barrier protects the bearing arrangement because the front end is equipped with a shaft seal, which supports installation in lubricated gear stages. Position sensing uses Resolver feedback, providing rotor angle feedback to the drive without a battery. For applications that use external holding devices, the unit is supplied without a blocking brake. The aluminum housing encloses the stator laminations and dissipates heat through the motor surface during normal operation.
