Product Description:
The MSK071E-0300-NN-M3-UP0-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and included in the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S unit, it delivers controllable torque and speed for industrial automation axes such as packaging stations, machine tool spindles, and gantry drives. The motor connects to the load with a keyed shaft and works with Rexroth drive controllers to provide precise closed-loop positioning.
The housing carries a protection rating of IP65, so dust ingress and low-pressure water jets do not affect internal components during cabinet-mount or open-machine installation. Heat is removed solely by natural convection, eliminating the need for external blowers or liquid circuits and simplifying panel layout. Position feedback travels over the Hiperface digital interface, which allows simultaneous transmission of encoder and diagnostic data between the motor and the drive. Inside the encoder, a pole wheel produces 16 signal periods per mechanical revolution, giving sufficient resolution for smooth velocity regulation. Sensor operation relies on capacitive measuring technology, providing immunity to magnetic fields and permitting higher shock tolerance than optical designs.
Multi-turn position tracking is retained through the power-off range of the drive because the encoder is a Multiturn Absolute device that counts shaft revolutions without battery backup. The mechanical platform is based on frame size 071 with motor length code E, offering a balance between continuous torque and installation depth for mid-range machinery. Ambient operation is specified between 0–40 °C, allowing direct use on factory floors without additional cooling loops, while insulation class 155 ensures winding integrity at elevated internal temperatures. The rotatable 240° feedback connector eases cable routing in confined cabinets. Winding designation 0300 matches the drive parameters for this motor and supports accurate current control.
