Product Description:

The MDD090C-N-020-N2L-110PL1 is a synchronous AC motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Supplied as a motor for digital drive controllers, it converts drive current into repeatable rotary motion for packaging stations and transfer axes. Digital servo feedback is integrated so the controller receives absolute rotor position without external encoders. A keyway shaft forms the primary power takeoff, while side B remains unmachined by design. The standard housing and an internal blocking brake permit secure load retention whenever power is removed.

The centering pilot on the flange measures 110 mm, aligning the motor to gearboxes and mounting plates without offset. This motor has size code 090 and length code C, which indicate the stack length and inertia. At standstill, the stator supplies 10.4 Nm of continuous torque while staying within allowable winding temperature. During operation, it reaches a nominal mechanical speed of 2000 rpm, which matches drive controllers that output 200 Hz. A sealed circular connector carries power and digital feedback signals, and the shaft end follows the standard keyway configuration to transmit torque to couplings without slip.

Dynamic and parking safety are managed by the integrated blocking brake, which applies 6.5 Nm of static torque to the rotor when the brake coil is de-energized. For in-process motion, the rotor is balanced to the Standard grade, so vibration levels remain compatible with bearings. All terminations exit on the left side of the housing, permitting cable runs alongside the machine frame and keeping bend radii consistent. An internal shaft seal prevents coolant spray or lubricants from migrating along the keyed shaft into the bearing cavity, supporting the sealing of the enclosure.
