Product Description:

The MS2N03-B0BYN-BSDK0-NNANN-F1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MS2N Synchronous Servo Motors series. As a compact drive element, it converts electrical energy into controlled rotary motion for positioning axes and cyclic handling tasks in industrial automation lines that require fast, repeatable movement. The unit uses a standard bearing set and has a black RAL 9005 varnish that protects the frame during continuous plant operation.

At the mechanical output, the motor supplies a maximum torque of 3.75 Nm while drawing up to 7.25 A from the drive, allowing peak load cycles to be executed without stall. Rated speed reaches 9000 rpm, and the low rotor inertia helps shorten acceleration times in pick-and-place sequences. For static holding, the standstill torque is 0.9 Nm when the windings are held at a 100 K temperature rise. A torque constant of 0.61 Nm/A relates commanded current to produced torque, which supports predictable drive response. Heat is removed by self-cooling through the housing, so no forced ventilation is required. The frame length B keeps the mass low without reducing magnetic active length, and the keyed shaft uses a shaft sealing ring to help maintain IP protection at the output side.

The motor has a voltage constant of 36.9 V/1000 rpm, which influences the back EMF seen by the inverter during high-speed moves. The three-phase stator has an inductance of 20.22 mH and a resistance of 14.3 ohms at 20 °C, and these values affect current ripple and thermal loading. Overall mass is 1.4 kg, which supports low moving loads in gantry and robot applications. Feedback is provided by a single-turn Hiperface encoder with 128 signal periods, and the rotatable double-cable M17 connectors simplify routing in tight cabinets. The motor is supplied without a holding brake, uses standard flange accuracy, and includes standard design features throughout.
