Product Description:

The MSK101E-0300-FN-S1-AP0-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. With motor size 101 and length code E, it is a large-frame variant that can supply high torque while keeping the line's standard housing and mounting arrangement. This standard design suits Rexroth drive packages used on CNC axes, packaging lines, and material-handling stations where precise closed-loop rotary motion is required. When paired with a suitable controller, the motor supports accurate acceleration, deceleration, and position holding during repeated machine cycles.

The motor uses liquid cooling; coolant channels in the stator remove heat from the windings and let it hold rated torque without derating. Its housing is certified to IP65, blocking dust and resisting water jets typically present inside sealed machine enclosures. Position feedback comes from an optical encoder that delivers 128 signal periods per turn, which the drive interpolates for fine speed and position control. Because the encoder is single-turn, absolute angle is retained within one revolution without mechanical gearing. Permitted ambient temperature spans 0 to 40 °C, and the motor is supplied without a holding brake to reduce mass where passive locking is not required.

Feedback signals exit through the Hiperface interface, allowing compatible IndraDrive controllers to read absolute position data and motor parameters automatically. The 0300 winding sets the rated impedance pair so the drive can deliver the correct current vector. Mechanical power is transmitted via a shaft with keyway, providing positive engagement with hubs or pulleys. The motor uses insulation class 155, allowing high winding-temperature tolerance during continuous duty. The power connector is positioned on the A-side of the housing to keep motor and cabinet cable routing on the same plane. This layout can simplify cable routing when the motor is installed beside adjacent machine components.
