Product Description:

The MSK070E-0150-NN-S2-UG0-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It provides precise rotary motion for positioning, feed, and spindle axes in industrial automation systems, where stable torque and accurate speed control are required. The motor is supplied without a holding brake, so any load that must remain fixed after power is removed needs external retention. Heat is removed by natural convection, which lets the housing dissipate waste heat without auxiliary fans. In automated equipment, this supports compact machine layouts and quieter operation.

Position feedback is handled by an optical encoder that produces 2048 signal periods per mechanical revolution, giving the drive fine position and speed data. The encoder signal supports precise commutation and smooth low-speed control when the axis must move steadily. Encoder communication uses the EnDat2.1 interface, which transfers feedback information over a serial link to the connected drive. The motor uses winding code 0150, which corresponds to the electrical characteristics expected by a matching controller. A rotatable 240° encoder connector helps align the cable exit with the available routing path and reduces strain where space is limited.

The design uses increased concentricity, which helps reduce runout when the motor is coupled to precision gearboxes or ball screws. A plain shaft supports direct connection through clamping elements or other suitable hubs, and the feedback system is a single-turn version for applications that reference position after startup. The shaft arrangement is suited to systems that use external couplings rather than integrated keyways. The motor is built in size 070 with frame length E, which supports a compact installation footprint while preserving the torque capacity expected from this housing. This layout suits multi-axis machines where installation space is limited and cable routing must remain orderly.
