Product Description:

The MDD090C-N-020-N2M-130PA1 is a synchronous servo motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. Designed to work with digital drive controllers, the unit converts electrical energy into precisely regulated rotary motion for positioning axes, conveyor sections, or tool spindles in automated machinery. Its mechanical interface, electrical connections, and feedback devices are suited to industrial motion loops where consistent torque and speed control are required. This arrangement allows the motor to respond quickly to changing command values during indexing, speed regulation, and hold-position tasks.

At the mechanical core, the motor sustains 10.4 Nm of continuous torque at standstill, so closed-loop drives can hold static loads without excessive heating. During motion tasks, a nominal speed of 2000 rpm is its rated operating speed under standard winding temperature. The centering shoulder measures 130 mm, which helps align the housing concentrically with the machine frame. A shaft seal helps keep lubricants inside and contaminants out, while the machined keyway simplifies power transmission to pulleys or couplings. Electrical terminations exit on Side A through a connector, which can help keep cable routing orderly near the machine frame. Standard rotor balancing supports smoother running during acceleration and deceleration.

Dynamic holding is handled by an internal blocking brake that applies 6.5 Nm of torque when the controller is disabled or power is lost. Position information is supplied by an integrated multiturn absolute encoder through digital servo feedback channels, so the drive can track shaft position across multiple revolutions. Frame size 090 corresponds to the C-length stack within the series, which helps match the motor to compatible mounts and axis layouts. The feedback system supports accurate restart behavior after brief interruptions, and the brake helps prevent unintended movement while the axis is at rest.
