Product Description:

The MSK071E-0300-FN-M2-UG2-RNNN is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is an IndraDyn S synchronous servomotor for precise motion control in industrial equipment. The motor converts drive commands into controlled torque and speed for automated tool changers, feeders, and coordinated multi-axis systems, where repeatable positioning and stable dynamic response are required. This layout suits machinery that depends on synchronized axis movement during repeated production cycles.

The motor uses liquid cooling, a closed-loop method that removes heat directly from the stator so continuous torque can be maintained without raising enclosure temperature. Its rotor and housing have increased concentricity, which reduces radial runout and supports accurate coupling to gearboxes or belt pulleys. Position data are transmitted through the EnDat2.1 digital interface, which provides absolute feedback together with bidirectional diagnostics. Inside the encoder, an optical disk generates 2048 signal periods per revolution, and a multiturn absolute scanning unit lets the controller retain shaft position across 4096 full revolutions after a power loss.

An electrically released holding brake provides 30 Nm of static torque to secure vertical axes when power is removed. The housing is rated IP65, which helps keep out dust and resists water jets on exposed machine frames. Power is transmitted through a plain shaft that accepts standard clamp couplings, and the encoder connector can be rotated 240° to simplify cable routing. Continuous operation is permitted in ambient temperatures of 0–40 °C. Additional identifiers such as motor size 071, length E, winding code 0300, and thermal class 155 help match the motor to compatible electrical and insulation requirements.
