Product Description:

The MSK101E-0450-FN-M1-BG0-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and positioned within the MSK IndraDyn S Synchronous Motors series. In automated production lines, it converts drive current from an IndraDrive controller into precise rotary motion and high-resolution position feedback for indexing tables, pick-and-place axes, and other closed-loop motion tasks. This type of motor is suited for applications that require repeatable acceleration, steady speed control, and accurate stopping behavior over frequent duty cycles. It is also well suited to axes that must respond quickly to changing load conditions without losing positional consistency.

Thermal loading is managed by liquid cooling, so heat is removed through an internal jacket instead of the motor surface. This supports continuous torque delivery even at low speeds, where self-ventilated motors often shed less heat. Position data is generated by an encoder that combines Hiperface communication, 128 signal periods per revolution, optical scanning, and multi-turn absolute feedback. Together, these encoder features let the controller track both shaft angle and completed revolutions after power loss. The motor is supplied without a holding brake, so external mechanical locking must be used if the load must remain fixed at standstill. Its standard design and plain housing maintain compatibility with common mounting frames, while size 101 and length E set the mechanical envelope. Winding code 0450 identifies the stator conductor layout and matches the electrical characteristics expected by the drive.

A housing rated at IP65 protects the windings and sensor components from dust and low-pressure water jets. The motor is intended for ambient temperatures from 0-40 °C, and the insulation system corresponds to class 155 for heat resistance within the winding assembly. Power and feedback leads exit on the B-side, which can simplify cable routing when the motor is mounted in line with a gearbox. Torque is transferred through a plain shaft, which avoids keyway stress concentrations and suits shrink-fit couplings. The liquid circuit helps keep copper temperature below the insulation limit during sustained operation.
