Product Description:

The MDD090A-N-020-N2L-110GA1 is an AC servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts the PWM output of a drive into regulated rotary motion for closed-loop industrial axes. This supports direct coupling to actuators and conveyor axes that require repeatable speed and position control. Its compact size and moderate inertia make it suitable for applications with frequent starts, stops, and direction changes.

Its nominal speed of 2000 rpm indicates the continuous rotor speed available under rated electrical conditions. The motor develops a continuous stall torque of 3.7 Nm, which supports static load holding without exceeding normal winding temperature limits. Precise mechanical alignment is assisted by a centering diameter of 110 mm, which matches common flange interfaces on machine plates and gearboxes. Electrical power and encoder connections exit on Side A, and a single circular connector groups the motor and feedback leads at one connection point. Motor size 090 with length code A gives the unit a compact frame for closed-loop motion tasks that need moderate torque and responsive acceleration.

The holding system provides 6.5 Nm of brake torque through a spring-applied, power-released blocking brake, so the axis can remain fixed when control power is removed. Rotor position is transmitted through digital servo feedback, giving the drive high-resolution commutation data and diagnostic information during operation. Output torque is delivered through a plain shaft, and a factory-installed shaft seal helps keep coolant or oil out of the stator chamber. Because the motor has one shaft end, couplings mount on the drive side only. The housing uses the standard finish and standard balancing for general indoor industrial service.
