Product Description:

The MDD093B-N-040-N2M-130PR0 is a synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded electrical power is converted into controlled rotary motion for positioning, conveying, and coordinated axis movement in automated machinery. The motor fits servo axes that require direct coupling, helping reduce backlash that can appear in transmission-based layouts. Closed-loop operation allows the associated drive to correct load-related deviations during acceleration, steady running, and stopping. This makes the unit suitable for fast industrial processes such as packaging, printing, and assembly equipment.

At standstill, the motor can continuously deliver 14.5 Nm of torque, with heat removed through the standard housing by natural convection. During operation, it reaches a nominal speed of 4000 rpm, supporting short cycle times on properly matched axes. Position and velocity are reported through Digital servo feedback (DSF), which works with an integrated multiturn absolute encoder so the drive can monitor motion without a homing sequence after startup. That feedback arrangement supports stable speed regulation and precise position tracking during repeated motion cycles. Mechanical alignment is aided by a centering diameter of 130 mm. Power and feedback conductors exit to the right and terminate in a connector, which helps keep cable attachment straightforward and organized.

The rotor uses standard balancing to help reduce vibration across the operating range. Torque is transmitted through a keyway, and the shaft includes a shaft seal to help limit the ingress of dust or coolant near the bearing area. This shaft arrangement is suited to keyed couplings and similar drive elements that require positive torque transfer. The motor is supplied without a blocking brake, so any power-off holding function must come from external hardware or controlled drive torque. Its B-length housing and single shaft end on side A support compact installation where multiple axes are mounted close together and quick indexing is required.
