Product Description:

The MSK101C-0300-NN-M2-BP2-RNNN is a brushless servomotor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It supplies closed-loop rotary motion for positioning tasks in CNC machines, packaging lines, and other automated cells. Its brushless design supports repeatable acceleration and deceleration during frequent start-stop cycles. This motor is suited for axes that require accurate positioning and stable motion over long production runs.

This motor uses natural convection for heat removal, so the housing dissipates energy without external blowers. Position data is transmitted through the EnDat2.1 serial interface, and the optical encoder provides 2048 signal periods per mechanical revolution for fine interpolation. The feedback system is multi-turn absolute, so it can retain position information across more than one turn after power loss. An electrically released brake provides 70 Nm of holding torque to secure the load at standstill. The housing has an IP65 rating to resist dust and water jets, and the approved ambient operating range is 0 to 40 °C. Passive cooling also helps simplify installation where auxiliary fan hardware is not desired.

Mechanical power is transmitted through a shaft with a keyway, which provides positive engagement with pulleys, couplings, or gearboxes. Insulation class 155 supports elevated winding temperatures, and winding code 0300 corresponds to the electrical values expected by MSK-compatible inverters. The motor uses frame size 101 with length C, which helps balance torque output with installation depth. Increased concentricity reduces radial runout for smoother rotation during precision motion. Power and brake conductors exit on the B-side, which can shorten cable loops when the motor is mounted on right-hand machine frames.
