Product Description:

The MDD025B-N-100-N2G-040FB0 is a compact synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves digital drive controllers by converting commanded current into proportional torque so that small positioning tables or handling modules reach target speed and angle with tight feedback control. The design pairs rapid acceleration with precise response while fitting into installations that demand low inertia and high spindle speed. Its compact format also suits axes where available mounting space is limited but accurate motion is still required.

At a continuous standstill load, the motor can deliver 0.60 Nm of torque. When driven by the inverter, it reaches a nominal speed of 10,000 rpm, allowing direct coupling to high-speed tooling stages without intermediate gearing. Mounting to a machine frame uses a centering flange diameter of 40 mm, which helps align the stator with the machine reference surface. Power and feedback conductors exit on side B of the housing, and closed-loop position data is supplied by resolver feedback. That feedback method supports stable commutation and speed control during repeated starts, stops, and direction changes. The motor has length code B and size code 025, which indicate its basic physical size.

The rotor uses standard balancing, which helps limit residual vibration during dynamic motion. A connector interface carries both power and sensor wiring, keeping the connection point compact at the motor housing. The shaft is a plain shaft and is supplied without a shaft seal, so sealing at the machine interface must be provided by the driven equipment when required. The motor is delivered without a blocking brake, so position holding at standstill depends on drive torque or external mechanical restraint. It also omits a shaft end on side B, which helps keep the rear profile short in compact machine layouts.
