Product Description:

The MSK101C-0450-FN-S1-LP2-NNNN is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. This servo motor is intended for closed-loop industrial positioning and speed control where compact torque density and integrated feedback are required. It uses a keyed shaft to transmit torque directly to couplings or pulleys, and its single-turn optical encoder allows the drive system to obtain absolute rotor position immediately at power-up. Because the encoder reports absolute position within one mechanical turn, the axis can begin controlled motion without a separate homing cycle after every restart. This is useful in packaging equipment, transfer systems, and gantry axes that depend on repeatable startup behavior.

The unit follows the FN cooling requirement, so it must be connected to a liquid cooling circuit to keep winding temperature within limits during continuous load. Rotor angle data are carried over the Hiperface serial interface, while an optical scanning system generates 128 signal periods per mechanical revolution for precise position feedback. Position retention during power-off is handled by an electrically released holding brake rated at 70 Nm, which helps keep vertical axes stationary when drive current is removed. The serial feedback channel combines position data and encoder communication in one interface, and the left-side power connector can simplify cable routing in machine layouts that place the motor with the connection area facing downward.

The housing carries an IP65 protection rating that helps keep dust and water jets away from the windings, and the motor is suitable for ambient temperatures of 0 to 40 °C. Thermal endurance uses insulation class 155, so the stator insulation system can withstand elevated winding temperature before aging accelerates. This operating range fits enclosed industrial equipment that is kept within normal room-temperature conditions rather than exposed outdoor service. The size 101 housing with length C and winding code 0450 gives the motor its assigned electrical and mechanical arrangement for matched drive operation.
