Product Description:

Bosch Rexroth Indramat manufactures the MDD025A-N-100-N2G-040MC1, a compact synchronous motor in the MDD Synchronous Motors series. The unit is intended for digital drive controllers where high spindle speed and limited mounting space are common. It converts servo drive current into rotational motion for positioning tables, pick-and-place heads, or small conveyor shafts in automated cells. In multi-axis systems, the motor can be used as a direct-coupled drive that sustains its rated velocity without intermediate gear stages, which helps improve repeatability in compact machine layouts.

The motor delivers a continuous standstill torque of 0.33 Nm, which is suitable for holding light loads at rest and for supporting smooth acceleration. Its rated speed reaches 10000 rpm, which suits high-cycle applications that require quick shaft reversals. Position and velocity signals are provided through resolver feedback mounted on the rotor, supplying analog sine-cosine signals to the controller. Mechanical alignment to the machine frame is aided by a centering diameter of 40 mm, and power plus feedback leads exit on side A through a connecting cable with coupling unit. The compact housing supports installation where available machine space is limited.

A blocking brake is fitted, and it supplies 1.0 Nm of static torque so the axis can remain fixed when power is removed. The shaft uses a keyway profile and terminates only on the drive side because the design does not include a side B shaft extension. The motor has size 025 and motor length code A, which keeps the overall length short for compact enclosure layouts. The motor is supplied without a shaft seal, so installations exposed to fluids require an external seal or protective coupling. Its resolver signals and brake control lines connect directly to the paired control electronics without additional converters.
