Product Description:

The MDD090C-N-040-N2L-110PL0 synchronous servo motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for integration with digital drive controllers, it converts electrical commands into controlled rotary motion for coordinated positioning and speed regulation in automated production equipment. The unit serves as an electromechanical actuator for pick-and-place heads, conveyors, and auxiliary spindles where fast response and repeatability are important. Its synchronous design allows the drive system to regulate torque and speed accurately during repeated start-stop cycles. It also pairs with compatible inverters for closed-loop motion control.

At standstill, the motor delivers a continuous torque of 10.4 Nm, allowing moderate loads to be held without overheating. During operation, it can reach a nominal speed of 4000 rpm, which requires the inverter to supply the corresponding electrical frequency. Mechanical alignment is aided by a centering diameter of 110 mm, and vibratory forces are limited through standard balancing. Cabling enters through a left-side cable entry, and the unit uses a connector interface for the power and encoder connections. The motor has a frame size of 090, while the C length extends the magnetic stack to increase torque density. A standard housing encloses the active parts and shields them from dust and light moisture.

Position data is returned to the controller through digital servo feedback (DSF), enabling high-resolution commutation and correction of positional errors. The output shaft uses a keyway shaft so pulleys or couplings can be locked against rotation, and a shaft seal helps prevent lubricant from escaping along the journal. The motor is supplied without a blocking brake, so static holding torque must be provided electrically or by an external mechanism when power is removed. To reduce axial length, the design uses only a shaft on side A and does not include a second shaft end.
