Product Description:

The MSK060B-0300-NN-M1-UP1-NNNN is a brushless AC unit manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a closed-loop servomotor, it converts drive-controller output into torque and speed. It also provides high-resolution position feedback, making it suitable for coordinated motion in robotics, material-handling stations, and forming equipment used throughout industrial automation.

This model is built in motor size 060 with the length class B, a combination that sets the frame dimensions and the active stack height of the stator. Winding code 0300 indicates the nominal voltage constant and current level matched to MSK drives. Heat is removed solely by natural convection, so the motor can be mounted without external fans or liquid circuits as long as ambient airflow is available. The mechanical output is delivered through a shaft with keyway, providing a straightforward coupling surface for pulleys or couplings while preventing slip under cyclic loads. A standard design housing and endbell allow direct attachment to compatible machine frames.

The integrated feedback subsystem uses a rotatable 240° connector that simplifies cable routing and carries signals from a multi-turn absolute encoder. Signal exchange with the drive takes place through the Hiperface interface, and rotor position is tracked via an optical scanning principle that generates 128 signal periods per mechanical revolution for fine velocity control. The multi-turn feature counts revolutions internally, eliminating battery-powered external counters. For power-off holding functions, the motor includes an electrically released brake rated at 10 Nm; this brake clamps the shaft when the control voltage is removed and releases automatically once power is restored. The rotatable connector helps with cable routing in compact spaces, and the brake supports holding functions on vertical axes.
