Product Description:
The MSK101E-0300-FN-S2-BP0-RNNN synchronous servomotor is produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It delivers regulated torque and speed for positioning axes, pick-and-place gantries, and packaging machinery across industrial automation lines. The motor is intended to run directly from Rexroth drive controllers, providing precise motion in coordinated multi-axis cells. Its operating role suits applications that need repeatable acceleration, stable speed control, and accurate response to changing load conditions during continuous machine cycles.
It employs liquid cooling, so heat is removed through a closed coolant circuit instead of surface airflow, allowing the motor to maintain rated output in enclosed installations. This cooling method also reduces the dependence on surrounding air movement, which is useful where cabinet ventilation is limited or airborne contamination must be controlled. The motor has a size 101 frame with length code E, giving it a larger stator package for higher continuous torque. Electrical behavior uses winding code 0300, which matches the phase resistance and inductance expected by the drive. The rotor and housing are machined for increased concentricity, reducing radial runout and improving coupling accuracy in precision gear or belt transmissions. A power connector on the B-side keeps the cable exit opposite the drive shaft, which can help simplify machine cable routing.
Position feedback is handled by an EnDat 2.1 interface that sends digital absolute data to the drive controller. The encoder provides 2048 signal periods, and it uses an optical measuring method for high immunity to magnetic fields. Because the encoder is single-turn, the controller receives the shaft angle within one revolution without requiring battery-backed revolution counting. This arrangement supports accurate startup behavior and stable closed-loop positioning during frequent indexing moves. Mechanical power is transmitted through a shaft with a keyway, which provides positive engagement with standard couplings and pulleys. The motor is supplied without a holding brake, so external load-holding measures are required when vertical axes must remain fixed after power is removed.
