Product Description:

The MSK100B-0300-NN-S1-LG0-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. In automated cells, it drives indexing tables, gantry axes, and precision tooling by supplying tightly regulated torque and speed through closed-loop control. This arrangement helps the connected drive hold position accurately during repeated acceleration, deceleration, and load changes while preserving a compact machine footprint.

Heat produced by the stator is removed through natural convection, so the housing fins maintain thermal balance without auxiliary blowers. This cooling method avoids external fans and keeps the motor housing simple for clean machine layouts. Position feedback is generated by an optical encoder that provides 128 signal periods per mechanical revolution and communicates over the Hiperface interface. Because the scanning system is single-turn, the drive can identify shaft position within one full rotation after power-up. A plain shaft allows backlash-free clamping couplings, and the motor uses length B with a standard design. The electromagnetic circuit identified by winding code 0300 sets the voltage constant and torque gradient expected by compatible drive amplifiers. Electrical power is routed through a left-side connector, which helps when cable chains approach from that direction. The unit is supplied without a holding brake, so external locking devices must secure vertical axes when power is removed.

The sealed housing has an IP65 rating that prevents dust ingress and resists low-pressure water jets, allowing installation on exposed machinery where splash protection is needed. The envelope designated as motor size 100 provides the inertia and torque density commonly used for medium-load servo axes and offers a mechanical format suited to larger couplings and mounting structures. The windings use insulation class 155, allowing elevated internal temperatures during operation without exceeding the thermal capability of the insulation system. Continuous duty is permitted within an ambient range of 0 to 40 °C, which suits standard factory conditions and supports steady operation without additional cooling hardware.
