Product Description:

The MDD090A-N-020-N2M-110PB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into regulated mechanical torque for axes that demand precise positioning. The unit is built in the 090 frame size and uses a standard housing to simplify integration with existing machine brackets and thermal enclosures. Its role in industrial automation is to drive conveyors, tooling heads, or indexing tables where deterministic speed control is required.

This motor supplies a continuous torque of 3.7 Nm at standstill, so it can support a steady holding load without exceeding normal thermal limits. The rated operating speed is 2000 rpm, which suits many positioning and speed-control tasks in automated machinery. A blocking brake is integrated and produces 11.0 Nm of static torque so the shaft can remain locked when power is removed. Electrical power, feedback, and brake lines enter on Side B, which helps keep cable routing consistent at the rear of the motor. Accurate mechanical alignment is aided by a centering shoulder of 110 mm. Closed-loop operation is supported through digital servo feedback (DSF), which returns position data to the drive for stable speed and position control.

An integrated multiturn absolute encoder stores position across power cycles, so the control system can retain shaft position information after shutdown. The motor has length code A, which keeps the housing compact and helps reduce inertia for responsive motion. The output shaft uses a keyway for positive torque transfer to a connected coupling or transmission element. Standard balancing helps reduce residual vibration during operation, and a shaft seal helps protect the bearing area from dust or coolant. Power leads terminate in a connector, and the rear side is kept clear for cabling, which supports orderly installation in machines with limited mounting space.
