Product Description:

The MSK071E-0450-FN-S2-UP2-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. This motor serves as a closed-loop actuator that delivers precise rotary motion to tooling spindles, pick-and-place gantries, and other automated axes where accurate speed, position, and torque control are required. Its single-turn optical feedback suits applications that complete a homing routine at startup, while the 071 frame and E motor length keep the package compact for tightly arranged machine axes.

The FN cooling arrangement requires continuous coolant flow, so this model uses liquid cooling to remove heat during high continuous torque operation. A mechanically rotatable through 240° encoder connector eases cable routing in tight cabinets. Position feedback is transmitted over the EnDat2.1 interface, and the integrated optical sensor provides 2048 signal periods for fine interpolation inside the drive controller. The housing is sealed to IP65, so dust and sprayed water do not enter the motor. Mechanical output is transferred through a shaft with a keyway, allowing torque transfer into standard keyed couplings without additional clamping elements. The increased concentricity design minimizes radial runout under load.

An electrically released holding brake provides 30 Nm of static torque, permitting vertical or suspended loads to remain stationary when power is removed. Thermal endurance corresponds to insulation class 155, allowing the windings to handle sustained current density within the motor’s operating range. Operation is permitted at ambient temperatures from 0 to 40 °C, and the coolant circuit must remain active during use to maintain that range. The 0450 winding code supports smooth acceleration and stable motion in applications that require accurate servo response.
