MDD025B-N-100-N2G-040GL0
The MDD025B-N-100-N2G-040GL0 is a brushless AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into precise mechanical output for positioning, speed control, and torque-control tasks in automated equipment. The motor uses a standard housing and balancing arrangement, which supports installation in axis modules that share the same mechanical footprint. This layout suits compact automation systems that require accurate response during repeated starts, stops, and speed changes.
Its continuous stall capacity is 0.60 Nm, which is the constant shaft torque the stator can supply without overheating while the rotor remains at standstill. The nominal mechanical speed reaches 10000 rpm, allowing the motor to serve high-speed pick-and-place systems or other duties that require rapid acceleration. Mounting alignment uses a centering pilot of 40 mm, which helps keep the motor concentric with the machine interface during installation. The motor is part of the 025 frame class, giving it a compact outer size. An internal resolver provides resolver feedback for closed-loop position control, and this signal lets the paired drive monitor rotor position continuously during operation.
Cabling exits on the left side because the power and feedback plugs share a connector oriented in that direction. The output uses a plain shaft with a shaft seal, which helps keep lubricants inside the housing while reducing the entry of splash at the bearing cavity. The motor is supplied without a blocking brake, so holding force must be provided by the servo drive or by external machine hardware when the axis is stopped. There is no secondary shaft extension on side B, and that single-ended layout suits machines that need only one driven shaft end. The standard housing protects the internal windings without additional coatings.
