Product Description:

Bosch Rexroth Indramat builds the MDD090A-N-020-N2L-130GR1 within its MDD Synchronous Motors series. This AC servo unit is intended to pair with the manufacturer’s digital drive controllers so that position, velocity, and torque commands can be executed with closed-loop accuracy. By converting electrical input into controlled rotary motion, the motor drives tooling axes, pick-and-place arms, or conveyor sections that require repeatable speed regulation and rapid dynamic response in automated machinery.

At a nominal speed of 2000 min⁻¹, the rotor reaches its rated angular velocity when the drive supplies the corresponding stator frequency, forming the baseline for velocity loops in machining cycles. During standstill, the motor can deliver a continuous torque of 3.7 Nm, enabling it to hold static loads without overheating. Feedback of shaft position is provided through digital servo feedback, which transmits absolute position data to the controller for tight servo alignment. The power and feedback leads exit on the right side through a sealed connector, simplifying cabinet wiring. Mechanical registration to the machine frame is achieved with a centering shoulder of 130 mm diameter that aligns the housing concentrically to the mounting surface.

To secure vertical axes or prevent drift at power-off, an integrated brake supplies 6.5 Nm of holding torque and is released electrically during operation. The output spindle is a plain shaft, avoiding keyways that might introduce backlash in clamp-style couplings. A fitted shaft seal blocks lubrication mist and dust from entering the bearing cavity and helps keep contaminants out when the flange is correctly mated. The motor belongs to size code 090, and its rotor is dynamically balanced to the standard grade to limit vibration at rated speed.
