Product Description:

The MSK100B-0400-NN-S1-AP1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended to supply closed-loop rotary motion to conveyors, pick-and-place axes, and similar assemblies where precise speed and position control are required. With a compatible drive, it converts commanded current into controlled shaft rotation for coordinated motion tasks. Its synchronous design allows the drive to regulate rotor position and speed with tight response during changing load conditions. This makes it suitable for packaging, handling, and other production systems that depend on repeatable axis behavior.

This motor dissipates heat through natural convection, eliminating the need for external cooling hardware. An enclosure rated at IP65 blocks dust and water jets so the stator windings stay dry in washdown environments. Position feedback reaches the drive via a Hiperface interface that carries data from an optical encoder generating 128 signal periods per revolution, enabling fine commutation and smooth torque production. For safety during power loss, an electrically released holding brake delivers 32 Nm of static torque. Because cooling is passive, the motor can be used where added airflow devices are undesirable or where space around the machine is limited. Winding code 0400 identifies the motor’s electrical characteristics, and the unit is supplied in the standard design configuration for this series.

The feedback device is a single-turn encoder, so the control system must track multi-turn motion externally. Insulation class 155 supports continuous service at elevated winding temperatures during high-duty cycles. Power leads exit on the motor’s A-side, which can simplify cable routing when the housing is mounted against machine frames. The motor uses frame size 100 with length code B and a shaft with keyway, allowing positive torque transmission to connected mechanical elements. The keyed shaft can be paired with couplings, pulleys, or gearbox inputs that require a secure mechanical connection. Allowed ambient conditions range from 0–40 °C, supporting use in standard factory environments.
