MDD025C-N-100-N2K-040FE0
The MDD025C-N-100-N2K-040FE0 is a compact synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to operate with digital drive controllers, the unit converts commanded current into precise rotary motion for light-duty positioning axes and small tool spindles in automated assembly cells and material-handling stations. Its compact format makes it suitable for installations where responsive motion and limited mounting space are both important. The motor is intended for controlled applications that benefit from accurate speed regulation and repeatable shaft positioning.
The motor reaches a nominal speed of 10000 rpm, allowing fast cycle times when paired with a suitable drive. Under stall conditions, it can supply 0.90 Nm of continuous torque, so the axis can hold a static load without overheating during normal operation. Size code 025 keeps the motor in a small frame that helps reduce inertia and supports quick acceleration. All electrical terminations exit on the left side, which can simplify cable routing in machine layouts that use side-mounted wiring. Rotor position is measured through resolver feedback, allowing the controller to monitor shaft angle continuously for closed-loop motion control.
A centering shoulder of 40 mm provides repeatable alignment to the machine frame during installation. Motor length code C gives the unit a longer active stack, which helps increase torque density without enlarging the overall frame diameter. Power is delivered through a connecting cable with a coupling unit, which avoids exposed terminals and provides a secure interface for the motor connection. The motor is supplied without a blocking brake, so any holding function must be provided by the drive or by external mechanical means. This arrangement is often preferred in high-speed applications where added brake drag is not desirable.
