R911249146
The R911249146 (MDD112C-N-030-N2L-130PB2) is a MDD series servo motor produced by Bosch Rexroth Indramat. This brushless motor features a laminated core with magnets, encoder, rotor shaft, windings, and an optional blocking brake. Its distinctive character is maintained by electronic commutation and permanent magnets. Its self-lubricated bearings imply no maintenance is required. An integrated sensor keeps a check on the motor winding temperature to prevent overload damage. The R911249146 (MDD112C-N-030-N2L-130PB2) motor, providing highly synchronous operation, also supports digital servo feedback when used alongside a suitable drive controller. It has a centering diameter of 130 millimeters, and the blocking brake is rated for 40 Nm.
The brake design allows shaft release when a 24 Volts DC signal is applied. A DIN 6885-1 standard keyway on the shaft ensures efficient torque transfer by preventing relative rotation. The motor is capable of achieving a nominal speed of 3000 RPM. The standard housing is suited for natural convection, and the optimal ambient temperature for operation is between 0 to 45 degrees Celsius. The motor has an IP65 protection class, with a black painted surface and a power socket on side B of the housing. Its power is sourced from the connector drive controller. It should be handled by trained personnel, used with approved accessories, and for specified applications only.
