MDD025C-N-100-N2G-040FB0
The MDD025C-N-100-N2G-040FB0 synchronous servo motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into accurate rotary motion for positioning and velocity control in automated machinery. The 025 frame size and C length code give the motor a compact overall package that fits small pick-and-place axes, labeling heads, and lightweight gantries. This short form factor also helps preserve clearance around nearby machine components when installation space is limited.
The motor uses a centering diameter of 40 mm, which helps the flange seat concentrically against the machine frame. Power and feedback conductors exit on Side B, and a molded Connector allows straightforward connection and removal. At stall, the motor sustains 0.90 Nm of continuous torque, so the driven load must remain within the thermal capability of the motor. With a nominal operating speed of 10000 rpm, it supports short acceleration ramps and high cycle rates in light-duty motion tasks. That speed range is useful on compact axes that use small pulleys, low-inertia couplings, or direct-drive arrangements.
Standard dynamic balancing reduces vibration during operation and helps maintain smooth rotation across the speed range. The motor is supplied without a blocking brake, so any holding function must be provided by the drive or by external machine hardware. Rotor position is returned through Resolver feedback, which provides analog sine-cosine signals for stable speed and position control. The output uses a Plain shaft in a standard single-ended arrangement, and it is supplied without a shaft seal, so the installation area should be kept free of coolant or oil splash. This shaft style works well with clamp-style couplings where simple alignment and low backlash are important.
