Product Description:

The MDD093A-N-020-N2M-110PB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is supplied for use with digital drive controllers, where it delivers closed-loop rotary motion to machine tools, printing lines, and handling modules. Integrated multi-turn absolute encoder electronics report shaft position to the controller over multiple revolutions, so the axis can resume controlled movement without a homing cycle after startup. This makes it suitable for positioning tasks that require repeatable startup behavior after power cycling or controlled stops. Standard housing geometry and rotor balancing support consistent installation on machines that use the same mechanical interface.

The motor’s nominal speed is 2000 rpm, which is its continuous operating speed under rated conditions. At standstill, it can produce a continuous holding torque of 9.2 Nm, helping the axis resist static loads while maintaining commanded position. A centering diameter of 110 mm provides a precise reference surface for concentric flange mounting. Power and feedback conductors exit on side B, which helps route cables away from moving parts on the drive end. Command and position data are transferred through digital servo feedback, allowing the drive to regulate current, speed, and position with high accuracy.

A 22 Nm blocking brake holds the shaft when power is removed, which helps prevent back-driving on vertical axes and during stopped conditions. The shaft uses a keyway for torque transmission through keyed couplings, and a fitted shaft seal helps protect the front bearing from lubricant loss and airborne contaminants. Standard balancing keeps vibration within the normal range for this motor design during routine operation. The A-length stator core keeps the motor compact, reduces overall mass, and helps it fit into space-limited axis layouts.
