MDD025C-N-100-N2G-040PB1
The MDD025C-N-100-N2G-040PB1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to operate with digital drive controllers, the unit serves as a rotary actuator in pick-and-place heads, small gantries, and indexing tables where precise motion and compact dimensions are required. Within an automation cell, it delivers closed-loop velocity and position control while withstanding repetitive cycles.
At standstill, the motor sustains a continuous torque of 0.90 Nm, allowing stable holding force without overheating when the axis pauses under load. Once released, the rotor can accelerate toward its nominal speed of 10,000 rpm, a figure that supports high cycle rates in lightweight assemblies. To secure the axis when power is cut, the integrated brake develops 1.0 Nm of holding torque, and this mechanical clamp is sized to restrain the shaft against reflected inertia from small payloads. Power and feedback conductors exit on side B, so cable routing can match other MDD 025 variants. Position data is returned through resolver feedback, giving the drive rotor angle information over the full speed range while remaining tolerant of electrical noise. A standard housing and factory balancing help limit vibration transmitted to the machine frame.
The front flange offers a centering diameter of 40 mm for precise seating in servo mounts. Electrical connections are made through a sealed connector that mates directly to the matching cable set. Torque is delivered by a shaft with a keyway, and axial sealing is maintained by a fitted gasket so sprayed coolants cannot migrate toward the bearings. The motor uses a blocking brake, which locks the shaft when command voltage is removed. Length code C and size 025 keep overall mass low, while the absence of a rear shaft end simplifies coupler alignment.
