Product Description:

The MDD090A-N-020-N2L-130GL2 is a brushless AC servo motor in the MDD Synchronous Motors series. It is built for use with digital drive controllers, where commanded current is converted into controlled torque and speed for positioning, indexing, and feed applications. This allows the motor to provide repeatable rotary motion in automated cells, transfer systems, and machine axes. In servo applications, this type of motor is commonly used where start-stop cycles, speed changes, and accurate path control are required. Its brushless design also reduces wear at the motor itself because no commutator brushes are used during operation.

The motor delivers a continuous standstill torque of 3.7 Nm, which allows it to hold load at zero speed within its thermal range. During motion, it reaches a nominal speed of 2000 rpm, giving a balance between axis response and controlled heating in the rotor and stator. A centering diameter of 130 mm supports accurate alignment during mounting, and all wiring exits on the left side through a sealed connector. Position information is provided by digital servo feedback (DSF), and the motor uses one industrial connector for both power and feedback connections. This connection layout helps keep cable routing compact in enclosed machine spaces.

An integrated blocking brake can apply 11.0 Nm when the drive is de-energized, which helps hold suspended or vertical loads during stops. The motor uses size code 090, and length code A indicates the shortest active stack in this frame format, which helps keep the motor compact. Motion is transmitted through a plain shaft with a fitted shaft seal to reduce the entry of coolant or other contaminants. The shaft is present only on the drive side, which avoids extra overhung mass on the opposite end and supports close-coupled machine layouts. This arrangement is useful where the motor mounts close to a gearbox, pulley, or ball screw support and no rear shaft extension is needed.
