Product Description:

The MSK071E-0300-FN-M1-UP0-NNNN is a motor engineered by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It serves as the rotary drive element in automated cells, translating electric power from compatible drives into tightly controlled position and velocity profiles for packaging lines, pick-and-place gantries, and CNC auxiliary axes. Its integrated feedback system supports accurate motion control during continuous production duty.

The stator jacket carries coolant, providing liquid cooling, so copper temperature stays within limits at sustained peak torque. Electromagnetic design is matched to winding code 0300, which corresponds to a coil arrangement for moderate current draw and responsive torque buildup. For feedback, the drive communicates through the Hiperface protocol; this bidirectional link conveys position, temperature, and electronic data to the controller. Inside the encoder, a disk divided into 128 signal periods generates sinusoidal traces that the drive can interpolate for very fine positioning. Field wiring is simplified by a connector that is rotatable through 240°, allowing the plug to turn to a more accessible angle inside crowded cabinets.

The measurement chain relies on an optical scanning method that reads transparent and opaque tracks without mechanical contact, which helps avoid wear in the position reference. Because the sensor is multiturn absolute, the motor reports the exact shaft angle and revolution count after power cycling, so homing moves are not required at startup. Mechanical coupling is handled by a shaft with keyway, giving positive torque transmission to pulleys or gearboxes and helping prevent slip under high acceleration. The unit is supplied without a holding brake, so applications that must maintain load position when power is off need an external clamping device or another holding method.
