Product Description:

The MSK101E-0450-NN-S2-BP0-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is installed in positioning axes and packaging stations where repeatable torque and speed must be delivered from a compact frame. By combining permanent-magnet technology with closed-loop feedback, the motor translates drive commands from a Rexroth controller into precise mechanical rotation for industrial automation. This arrangement supports smooth speed control, repeatable positioning, and stable torque delivery during cyclic machine operation.

Heat is removed through natural convection, so no external fan or liquid circuit is needed, and the stator design maintains increased concentricity to help minimize runout during high-speed motion. Position data is sent over the EnDat2.1 bidirectional interface, and each revolution is subdivided into 2048 signal periods by an optical measuring system for accurate fine-angle resolution. The feedback path allows the drive to monitor rotor position continuously during speed changes and short positioning moves. The motor has a shaft with a keyway for standard keyed couplings, while motor length code E and winding code 0450 set the active stack depth and voltage-to-torque relationship. This combination suits medium-inertia loads while keeping the housing compact for machine layouts with limited space.

The encoder provides absolute feedback in a single-turn format, so position is available within one mechanical revolution. Because the unit is supplied without a holding brake, the axis must rely on drive torque or an external clamp to secure vertical loads during power-off conditions. The motor uses frame size 101, which matches the corresponding flange and sealing components for this housing. The power connector is located on the B-side, which helps route cables parallel to the machine bed and can reduce cable bending near the housing.
