Product Description:

The MDD093B-N-040-N2M-130GR0 is a synchronous motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, it supplies controlled rotary motion for indexing tables, handling modules, and packaging stations throughout industrial automation cells. Its 093 frame size suits medium-power axes where space efficiency and dynamic response must coexist. The motor is intended for applications that need repeatable positioning, stable speed control, and fast response during frequent start-stop cycles. This makes it suitable for servo axes that alternate between rapid indexing moves and precise dwell positions.

The motor has a centering pilot diameter of 130 mm, allowing precise seating against gearboxes or mounting flanges. During continuous stall, the stator can maintain 14.5 Nm of torque, which helps the axis resist load movement at low speed or standstill. Under rated excitation, the rotor can reach 4000 rpm, supporting fast positioning and short cycle times. Power and feedback conductors exit on the right side through a keyed connector, which keeps cable orientation fixed and helps prevent misalignment during installation. Position data is provided by an integrated multi-turn absolute encoder, so the controller retains shaft position information after power is removed. The B length code gives the motor an intermediate stack that keeps inertia moderate for responsive acceleration.

Feedback to the drive is transferred through digital servo feedback (DSF), enabling accurate current, speed, and position control. Mechanical holding must be handled externally because the motor is supplied without a blocking brake, which suits machines that use a separate clamp or brake at the load. A plain shaft protected with a shaft seal helps keep lubricant inside attached mechanics and limits contaminant entry at the shaft opening. The standard housing removes heat through its mounting surfaces, so the machine structure becomes part of the cooling path during operation. The shaft end arrangement omits a side-B extension, which reduces overall length and leaves more room around the rear of the motor for connected cables.
