Product Description:

The MDD090C-N-030-N2L-110PL1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers and provides rotary motion for positioning axes and other controlled machine movements. The motor uses the 090 frame with length code C, which gives a useful balance between compact installation space and available surface area for heat dissipation. Standard housing construction and standard dynamic balancing support installation on rigid machine plates, and the unit has a single shaft end without a side-B extension for common coupling layouts. This format is commonly used where repeatable acceleration, deceleration, and short settling times are needed in packaging, handling, and transfer equipment.

The mechanical interface uses a 110 mm pilot to align the motor face with a gearbox or machine frame. When the shaft is locked electromagnetically, the rotor can supply 10.4 Nm of continuous torque at standstill, and commanded motion reaches a nominal speed of 3000 rpm. Closed-loop position and speed control are supported by the integrated Digital servo feedback encoder. Power, signal, and brake conductors enter through a single connector mounted on the left side, and a shaft seal helps keep splash and dust away from the bearing set. This cable entry layout can simplify routing where cabinet clearance or nearby tooling limits the available bend radius around the motor.

The motor includes an internal blocking brake that engages automatically when power is removed and holds up to 6.5 Nm. Output torque is transferred through a keyway shaft, which supports direct connection to pulleys, gears, or belt wheels without relying only on a plain clamping surface. This arrangement helps the axis remain in position during stops, and it supports repeatable restarts in applications that need controlled holding between motion cycles. Because the brake is built into the motor, no separate external holding device is required at the motor housing for normal stationary retention. The brake and shaft arrangement are suited to machines that pause frequently between indexed movements.
