Product Description:

The MSK100B-0300-NN-M1-AP0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for positioning and speed-controlled axes, where it transforms drive commands into rotary motion for packaging equipment, machine tools, and automated handling stations. The integrated encoder gives the connected drive continuous feedback, allowing correction of position and speed during changing load conditions. The motor has size 100 with length code B and uses winding code 0300 for this frame. That combination suits applications that need repeatable indexing and stable servo response through frequent start-stop cycles.

This motor disperses heat through natural convection, so the installation should allow free air circulation around the housing instead of relying on forced-air ducts. Its enclosure is rated IP65, which keeps out dust and resists low-pressure water jets during washdown cycles. Operation is permitted from 0 to 40 °C, and current must be reduced outside that ambient range. Class 155 insulation supports elevated winding temperature before thermal aging accelerates. Power enters through an A-side connector, which places the cable outlet toward the shaft end and can simplify routing on compact axes. The motor uses a keyed shaft for positive torque transfer to couplings, pulleys, or gearbox inputs. It has a standard design without optional sealing or blower hardware, and a holding brake is not included, so any power-off load holding must be provided externally.

The feedback system uses a Hiperface interface to send absolute position data to the controller. Inside the encoder, an optical scanning system provides 128 signal periods per mechanical revolution, and the gear train supports multiturn absolute position tracking. Absolute position is therefore available immediately after power-up, so a homing move is not required after every restart. The encoder data also supports precise commutation and smooth low-speed control during indexing or steady-speed operation. Because cooling relies only on ambient air, the stated cooling method and temperature range should be observed during operation.
