Product Description:

The MDD090C-N-040-N2L-130GA0 is a synchronous AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for digital drive controllers, where commanded current is converted into controlled rotary motion for positioning and speed-regulated machine axes. Its synchronous design supports closed-loop motion tasks that require repeatable torque response and stable operation under changing loads. This makes the motor suitable for feed axes, handling systems, and other automated equipment that depends on controlled acceleration, deceleration, and steady running speed.

The motor has a nominal speed of 4000 rpm, allowing fast cycle times when paired with compatible inverters. At standstill, it can deliver 10.4 Nm continuously, so holding load torque does not overheat the windings during rated operation. Accurate mechanical alignment is aided by a centering diameter of 130 mm, and the rotor is balanced to a standard grade to help limit vibration at higher speeds. Power and feedback conductors exit on side A through a pre-wired connector, which can simplify cable routing where rear cabinet space is limited. The housing uses a standard sealed design, and a shaft seal is installed to help keep lubricant in and contaminants out. Because the cable exit is grouped at one end, the motor can fit neatly into compact machine layouts.

Position data is returned through Digital servo feedback (DSF), so the controller receives high-resolution encoder information for speed and position loops. This feedback arrangement allows the drive to monitor rotor position during acceleration, deceleration, and low-speed control. The motor uses the 090 frame size, and its length follows the C code for the motor depth. A single-ended configuration is used, so there is no shaft end on side B and the motor can fit installations with limited rear clearance. The output uses a plain shaft, making it suitable for friction or clamping hubs. The motor is supplied without a blocking brake, so any holding function must be provided by drive torque or by an external mechanical device.
