Product Description:

The MDD090C-N-040-N2L-110PA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts command currents from an inverter into controlled rotary motion for industrial automation axes. A blocking brake is integrated so stationary loads remain secured when the drive is de-energized, and a shaft seal helps prevent lubricant migration into the motor enclosure. Standard housing dimensions and balancing support installation on existing mechanical frames.

At standstill, the motor can deliver a continuous torque of 10.4 Nm, providing steady torque for vertical or friction-loaded stages. When energized at rated voltage and frequency, its rotor reaches a nominal speed of 4000 rpm, allowing high-throughput positioning without gear reduction. Mechanical placement against a machine plate is guided by a centering diameter of 110 mm, which aligns the stator concentrically to coupled loads. During emergency stops, the blocking brake supplies 6.5 Nm of holding torque, keeping the shaft immobile until power is restored. Position and velocity are returned to the controller through digital servo feedback, enabling tight closed-loop regulation.

Coded as size 090 and length class C, the motor fits the dimensional envelope used in its series. Power and feedback conductors are routed on side A, and they terminate on a single connector, reducing cabinet wiring time. Standard balancing limits vibration when the keyway shaft is coupled directly to pulleys or couplings, while the absence of a side B shaft end simplifies installation in tight racks. The standard housing tolerates typical shop-floor ambient conditions, and the built-in shaft seal protects the internal bearings from coolant splash or dust.
