Product Description:
The MSK060B-0300-NN-S2-UG1-RNNN is a compact rotary servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended for precise position and velocity control in automated machinery, enabling coordinated motion on packaging lines, pick-and-place modules, and CNC auxiliary axes. In these applications, the motor converts commanded current into controlled rotary motion for indexing, transfer, and feed tasks. A plain output shaft supports backlash-free coupling in compact machine layouts.
The motor is cooled by natural convection, so heat is dissipated through the housing without forced airflow. Drive wiring is supported by a rotatable 240° connector that allows the cable outlet to be positioned for strain relief while maintaining clearance. That cable orientation can help when the motor is mounted close to guards, brackets, or neighboring axes. Position feedback is transmitted through the EnDat2.1 serial interface, which carries absolute position data and diagnostic information to the drive. Inside the housing, an optical encoder provides 2048 signal periods per revolution for smooth velocity regulation and accurate positioning. The housing is sealed to IP65, which keeps out dust and protects internal components from low-pressure water jets. The increased concentricity design supports accurate coupling alignment and stable shaft rotation. Additional details include motor size 060, length code B, and winding code 0300.
Load-holding capability is provided by an electrically released brake rated at 10 Nm. When the brake coil is energized, the rotor is released, and loss of power clamps the shaft during standby. This arrangement helps prevent unintended movement when the axis is stopped. The encoder is a single-turn design, making it suitable for axes that home at startup. Reliable operation is specified within an ambient range of 0 to 40 °C. The windings use Class 155 insulation, which permits conductor temperatures up to 155 °C before thermal aging accelerates. This temperature class supports normal industrial duty cycles where winding heat rises during repeated acceleration.
