Product Description:
The MSK071E-0300-FN-M1-UP2-NNNN is a synchronous servo motor from the MSK IndraDyn S Synchronous Motors series manufactured by Bosch Rexroth Indramat. Classified as an IndraDyn S servo motor, it combines a permanent-magnet rotor with integrated feedback to drive positioning or speed-controlled axes in machining centers, packaging stations, and material-handling systems. The motor uses size 071 with construction length E, which gives it a compact profile while still accommodating the winding, brake, and cooling hardware. This compact housing is useful where couplings, guards, and adjacent machine parts limit installation space. The motor is intended for systems with continuous liquid circulation, indicated by the FN cooling requirement.
Heat is removed through liquid cooling, and code FN indicates that an external coolant circuit must remain active because full torque cannot be sustained without it. An electrically released holding brake delivers 30 Nm of static torque, allowing vertical axes to remain secure when power is removed. The motor uses winding code 0300, which matches the electrical values expected by compatible IndraDrive amplifiers. Environmental sealing meets IP65, so dust ingress and water jets will not reach internal parts. For fine commutation, the optical encoder generates 128 signal periods per revolution, and the thermal system uses insulation class 155 for extended winding durability.
The feedback assembly stores absolute rotor position over multiple revolutions through a multi-turn absolute track and communicates this data through the Hiperface interface. This feedback arrangement supports accurate startup behavior because the controller can retain position information after power cycles. The connector can be rotated 240° to simplify cable routing inside tight cabinets and crowded machine spaces. Mechanical power is transferred through a shaft with a keyway, which supports positive coupling to gears or pulleys. Reliable operation is permitted at ambient temperatures from 0 to 40 °C, and the standard housing does not require extra protective options for that range.
