Product Introduction
The Bosch Rexroth MSK101E-0200-NN-M1-AG3-NNNN is a permanent magnet synchronous servo motor in the IndraDyn S series. It delivers maximum continuous torque in the MSK101 family for extreme loads in large CNC machines, heavy robotics, printing presses, packaging systems, and material handling when connected to IndraDrive drives.
It includes a multi-turn hiperface encoder for absolute positioning over multiple revolutions, natural convection cooling, plain shaft with sealing ring, and high-torque holding brake. This length E variant supports 400–480 V supplies, provides IP65 protection, and excels in sustained heavy-load scenarios requiring strong brake holding for vertical or safety-critical axes.
