MDD025C-N-100-N2K-040GL1
The MDD025C-N-100-N2K-040GL1 is a compact synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it delivers rapid rotary motion to pick-and-place heads, small indexing tables, and semiconductor handling stations where quick acceleration and repeatable positioning are required. Its 025 frame size pairs a modest rotor diameter with a C-length stack, and the standard housing fits narrow enclosures without requiring extra cooling hardware or unusual mounting space.
At standstill, the motor delivers a continuous torque of 0.90 Nm, sustaining the load while copper and lamination losses remain within thermal limits. Once driven by the inverter, the rotor reaches a nominal speed of 10,000 rpm, providing the surface speed needed for fine incremental positioning at high cycle rates. A blocking brake rated at 1.0 Nm prevents back-driving of vertical axes when mains power is disabled. Power and feedback leads exit on the left side through a sealed connector, which helps simplify cable routing in slender control cabinets. Precise concentricity is achieved with a 40 mm centering diameter in the flange, and the motor uses a standard balance grade to keep vibration low across the speed range. A radial shaft seal protects the front bearing from coolant splash.
Closed-loop control is supported by an integrated absolute encoder that provides multi-turn position data without requiring a homing sequence after startup. For drives that prefer analog interpolation, simultaneous resolver feedback is available, allowing dual feedback channels in the same motor package. Torque is transmitted through a plain shaft made to h6 tolerance, and the motor is supplied without a side B shaft end so the rear face remains clear for the brake and cable hardware.
