Product Description:

Bosch Rexroth Indramat builds the MS2N07-D0BRN-BMVK2-NNANN-F1 as part of the MS2N Synchronous Servo Motors series. This motor serves as a drive element for position-controlled axes in industrial automation, where fast speed changes and accurate torque delivery are required. In servo systems, it converts electrical input into controlled rotary motion for axes that must start, stop, and reverse with precision. It is suitable for automated machinery that depends on repeatable motion and stable closed-loop response.

During continuous operation, the motor develops a 4.64 kW mechanical output while drawing a nominal phase current of 12.15 A. At that operating point, it produces 14.7 Nm of shaft torque at a synchronous speed of 4500 rpm. The electromagnetic force constant is 1.38 Nm/A, which ties torque production directly to current in the control loop. A winding inductance of 5.06 mH and a resistance of 0.327 Ω affect the electrical time constant and drive tuning. Self-cooling eliminates the need for external airflow devices, and the standard bearing set supports low-inertia rotor dynamics for rapid acceleration. The stator has a standard RAL 9005 black varnish finish, and the 140 mm flange with frame length D supports accurate mounting. Power and feedback are routed through a rotatable double-cable outlet fitted with M40 and M17 connectors.

For transient demands, the motor can reach 79.7 Nm of peak torque when cold, and the electrically released brake supplies 36 Nm to lock the shaft at standstill through a 24 V release circuit. Mechanical overspeed protection is set at 6000 rpm. A back-EMF gradient of 83.9 V/1000 rpm guides drive-side voltage selection. Motion feedback comes from a multiturn Hiperface encoder with 128 signal periods per revolution and 4,096 stored absolute revolutions. This feedback arrangement allows the drive to retain position information within the encoder’s multi-turn range. The 32 mm keyed shaft includes a sealing ring for IP-compatible oil retention.
