Product Description:

The MSK075C-0450-NN-M1-UP0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. Within automated handling cells, packaging machinery, and printing lines, the motor supplies closed-loop torque and position control to axes that must accelerate quickly and settle precisely. Its frame size places it in the mid-range of the series, giving a balance between continuous torque capability and a compact envelope for cabinet or base plate mounting.

This unit relies on natural convection, so heat leaves the housing without fans or external coolant. Feedback cabling attaches to a rotatable 240° connector, and the plug can be turned during wiring to ease strain relief in tight spaces. Position data is exchanged through the Hiperface serial interface, allowing absolute position data and motor parameters to be transmitted to the drive controller. Inside the encoder, an incremental track provides 128 signal periods per mechanical revolution, and an optical scanning method helps keep interpolation error low across the speed range. Winding code 0450 identifies the electrical resistance and inductance set used for pairing with IndraDrive power sections, and the standard housing design maintains IP65 sealing around the stator laminations.

The sensing system records turns with a multiturn absolute mechanism, so the controller can retain absolute shaft position after a power cycle. Because the motor is supplied without a holding brake, static load retention must be handled by the drive or by external mechanics when power is off. Output is transferred through a shaft with keyway, giving a positive mechanical lock to pulleys or couplings and helping prevent slippage under peak torque. The motor length C keeps overall depth short, which helps the motor fit into compact multi-axis machine layouts.
