Product Description:

The MDD090A-N-040-N2M-110GR0 is a synchronous motor from Bosch Rexroth Indramat's MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts current into controlled rotary motion for conveyors, tooling, and pick-and-place equipment. Permanent-magnet excitation and electronic commutation help maintain stable torque and speed in precise industrial motion tasks.

It delivers 3.7 Nm of continuous standstill torque, allowing an axis to hold loads without excessive heating at rest. A nominal speed of 4000 min⁻¹ supports quick acceleration and steady running across typical positioning ranges. The plain shaft works well with clamp couplings, and the shaft seal helps limit fluid ingress. Feedback is handled through digital servo feedback (DSF), which supplies high-resolution position and velocity signals for accurate control.

A centering diameter of 110 mm helps the housing register accurately to a machine plate or gear unit. Power and encoder connections exit on the right side, which can simplify cable routing where nearby components limit access. An integrated multiturn absolute encoder retains position data over multiple revolutions, so the axis can recover reference information after power loss without a homing cycle. The motor is built without a blocking brake, so holding at standstill must come from drive torque or an external mechanical device.

Wake Industrial stocks this motor and offers same-day shipping options when rapid replacement is required. Quotes remain valid for 30 days, which helps buyers plan maintenance purchases during approval cycles. Customers can use the chat tool available on the website for questions about type codes, general specifications, or fault indicators.
