Product Description:

The MSK100A-0300-NN-S1-AP1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts electrical energy into controlled torque and speed for positioning and feed axes in packaging stations, metal-cutting centers, and material-handling gantries. Its compact frame mounts directly to machine plates and works with compatible drive amplifiers in closed-loop motion systems. This type of motor is suited to applications that need repeatable acceleration, steady running, and accurate response to changing load conditions.

Heat is removed by natural convection, so the housing dissipates losses without auxiliary fans. Because cooling is passive, the motor does not require a separate blower or liquid circuit at the housing. An electrically released brake provides 32 Nm of holding torque to keep vertical or suspended loads in place when power is removed. The housing is sealed to IP65, which helps keep dust and water jets away from internal components. Position data is transmitted through Hiperface, and the optical feedback system provides 128 signal periods per revolution for stable low-speed control and accurate position tracking.

The electrical interface is located on the A-side of the stator, which can help shorten cable routing in compact machine layouts. Mechanical output is provided through a shaft with a keyway, allowing positive torque transmission to pulleys or couplings during repeated reversals. This shaft arrangement supports driven components that cannot rely on friction alone to prevent slip. Insulation class 155 supports elevated winding temperatures when the surrounding air stays within 0 to 40 °C. The motor uses a standard design variant with a single-turn encoder, winding code 0300, and size 100 with A length.
