Product Description:
The MSK071E-0300-NN-S1-UP0-NNNN is a servomotor manufactured by Bosch Rexroth Indramat and part of the MSK IndraDyn S Synchronous Motors series. Classified as an IndraDyn S synchronous servomotor, it supplies closed-loop rotary motion for positioning and velocity duties within industrial automation lines. The motor uses the standard design category with frame size 071 and length code E, allowing it to fit machine spaces intended for this housing size. It is suited for servo-controlled axes where the drive must regulate speed and position during repeated starts, stops, and directional changes.
Heat is removed by natural convection, so ambient air circulation is the only cooling path and no fan or liquid loop is required. This cooling method keeps the motor free of auxiliary cooling hardware and helps simplify the surrounding machine layout. Connection to the drive is simplified by a 240° rotatable connector, which allows the cable outlet direction to be adjusted without extra hardware. Signal transmission uses the Hiperface interface, and an optical sensor disc inside the encoder provides 128 signal periods for high-resolution sine-cosine feedback, smooth interpolation, and accurate commutation.
For absolute position reporting, the encoder is configured as Singleturn, so it reports one mechanical revolution of absolute position data and leaves extended tracking to the control system. The motor is supplied without a holding brake, which means static load retention must be handled by the drive or by an external clamping device when the axis is stopped. Torque is transmitted through a shaft with keyway, which matches common coupling styles and helps prevent slip under cyclic loads. Winding code 0300 sets the electrical characteristics used by compatible drive systems, including resistance, inductance, and back-EMF values.
