MDD025A-N-100-N2K-040GC0
The MDD025A-N-100-N2K-040GC0 is a compact synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts commanded current into precise rotary motion for positioning tasks and high-speed following axes in automated assembly or inspection cells. In this role, the motor responds to current commands from a digital controller and supports accurate speed and position changes during short, repeatable machine cycles. The compact housing, plain shaft, and standard balancing help it run smoothly when it is connected to miniature geartrains or direct-drive spindles in space-limited equipment.
At standstill, the motor can deliver a continuous torque of 0.33 Nm, which indicates the load it can support during continuous stationary operation. It reaches a nominal mechanical speed of 10000 rpm, making it suitable for applications that require rapid indexing with minimal overshoot. Mechanical alignment is supported by a 40 mm pilot diameter, while power and feedback conductors exit on Side A to simplify cable routing when the flange faces the machine interior. The unit is supplied with a connecting cable with coupling unit, so installation only requires mating the preassembled connector set. This layout is useful in compact machine frames where cable space is limited around the motor body.
Position feedback is provided by resolver feedback, which supplies angular information at high update rates, while the integrated absolute encoder reports position without a homing cycle after power-up. Using both feedback devices allows the paired controller to track rotor angle during motion and retain position information after shutdown. The motor is supplied without a blocking brake, so any holding function during power loss must be provided by drive torque or an external clamp. A factory-installed shaft seal helps keep coolant splash and fine dust from reaching the bearing cavity, supporting reliable operation in compact machine spaces.
