Product Description:

The MDD090C-N-040-N2M-110PL0 synchronous motor is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It works with digital drive controllers and converts regulated current into precise rotary motion for positioning axes, pick-and-place heads, and other automated stations. Its standard housing and balanced rotor suit both machine-integrated layouts and enclosed installations where repeatable motion, stable feedback, and predictable mechanical behavior are required over long duty cycles.

Mechanical interface dimensions start with a centering diameter of 110 mm, giving repeatable concentric alignment to gearboxes or pulley hubs. The power and signal plugs are oriented to the machine’s left side, which can simplify cable routing in multi-axis frames. At standstill, the rotor delivers 10.4 Nm of continuous torque, allowing the axis to resist static process loads without overheating. Under rated excitation, it can reach a speed of 4000 rpm, matching the operating range of compatible high-response inverters. Rotor position is measured by an integrated multiturn absolute encoder, so the controller can retain angle and revolution data after power cycling and resume motion with immediate position awareness.

The signal chain between motor and controller is completed through digital servo feedback, which supports accurate speed control and stable closed-loop operation. A shaft seal protects the front bearing area from lubricant splash and airborne dust in production environments. Torque is transmitted through a keyway shaft end, allowing secure coupling to pulleys or similar driven elements under acceleration. The motor is supplied without a blocking brake, so holding force must be provided by external mechanics or drive-generated torque when the axis is stopped. Its compact length code C helps the motor fit installations where axial space is limited.
