Product Description:

The MSK071E-0450-FN-M1-UG2-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Designed as a compact rotary actuator, it interfaces directly with Rexroth drive controllers to position tooling, conveyors, or pick-and-place heads with high repeatability. The motor incorporates an electrically released holding brake so axes can be secured when power is removed, and it uses the FN cooling variant to support continuous industrial duty.

Thermal management is handled through liquid cooling, allowing higher continuous currents than air-cooled units that share the same 071 frame size. A rotatable 240° encoder connector simplifies cable routing, while the encoder uses the Hiperface digital interface and delivers 128 signal periods per revolution through optical scanning. Because the feedback device is multi-turn absolute, the controller can retain shaft position through power cycles without a homing routine. An electrically released brake supplies 30 Nm of static torque to hold the load without drive torque. The motor housing is sealed to IP65, which protects internal components from dust and low-pressure water jets, and the plain shaft supports coupling to gearboxes or direct-drive loads.

The electromagnetic package uses winding code 0450, which matches the stator resistance and inductance to compatible IndraDrive amplifiers. Continuous operation is permitted within an ambient range of 0 to 40 °C, and staying within that range helps prevent condensation and preserve lubrication on the plain shaft. The insulation class is 155, indicating materials rated for winding temperatures up to 155 °C before accelerated aging occurs. A standard mechanical design, motor length E, and the 071 frame support a balance of power density and installation depth for mid-range automation axes.
