Product Description:

The MDD112D-N-020-N2M-130PA2 is a three-phase synchronous servo motor from the MDD Synchronous Motors series by Bosch Rexroth Indramat. Designed for use with digital drive controllers, it converts commanded current into controlled rotary motion for automated machinery that requires precise torque, speed, and position regulation. The motor is intended for closed-loop motion tasks where repeatable positioning and controlled acceleration are required over frequent operating cycles. Integrated feedback and an internal blocking brake allow the motor to hold axis position when the drive is disabled, which helps reduce the need for separate holding components in compact motion systems.

The centering diameter is 130 mm, which allows accurate alignment with flanged gearboxes and machine interfaces. Power and feedback leads exit on Side A through a single connector, keeping cable routing on one face of the machine frame. Standard balancing helps keep residual vibration within normal limits during rotation. At stall, the motor can deliver 38.0 Nm of continuous torque without overheating. Position data is supplied by an integrated multi-turn absolute encoder, so the controller can recover shaft position after power cycles.

Electrical feedback is transmitted as digital servo feedback (DSF), supporting high-resolution commutation and velocity control at a nominal speed of 2000 rpm. When mains power is removed, the blocking brake provides 40.0 Nm of holding torque, and the shaft seal helps limit the entry of dust and oil. The output shaft uses a keyway for positive coupling to pulleys or couplings, and the shaft is present only on the drive side rather than as a through-shaft design. This arrangement supports direct integration with common machine elements while keeping the rear of the motor clear of rotating extensions.
